Ltd. is an Indian manufacturer, founded in 1996, of pigment dispersion colorants for polyurethane, mould release agents, in-mould coatings, PU lacquers, thinners, mould cleaners and MDI pre-polymer binders. Plants are in Bhiwadi, Rajasthan, and the corporate office is in Gurugram, Haryana."},{"q":"Is Chemie a manufacturer or a trader?","a":"Chemie is a manufacturer. Pigments are dispersed in-house at our Bhiwadi plants. Solvent-based products (in-mould coatings and release agents) are made at a dedicated second plant."},{"q":"Which regulations do Chemie colorants meet?","a":"Chemie PU colorants are REACH and RoHS compliant. Fire-retardant colour pastes based on melamine and graphite are available for UL94 requirements. PU mould cleaners are formulated to EU REACH norms. Request written declarations and SDS for the grades you are evaluating."},{"q":"Does Chemie provide samples and trials?","a":"Yes. Shades are developed in the Chemie laboratory against your sample or reference, cast in your PU system, and approved before production. Plant-trial support and a master standard for repeat orders are part of the process."},{"q":"What information does Chemie need to quote accurately?","a":"Product family, industry and part, PU system or mould details, target shade or finish, exposure and compliance needs, annual and first-order volumes, pack size, delivery location and timeline. The RFQ checklist on the supplier profile page lists every field."},{"q":"When is Chemie not the right supplier?","a":"Chemie does not supply polyols or isocyanates, thermoplastic colour masterbatch, or catalogue-only standard colours with no development step. Ask before assuming suitability for regulated food-contact or medical applications. Chemie will also advise against silicone release agents where parts must be painted or bonded."},{"q":"How does Chemie keep shade consistent from batch to batch?","a":"By retaining an approved master standard, controlling fineness of grind, tinting strength and viscosity on every batch, and issuing batch values on the certificate of analysis. Consistency also depends on dosing and storage at the customer, covered in the shade-variation troubleshooting guide."},{"q":"Can one supplier cover colorant, release agent and in-mould coating?","a":"Yes. Chemie makes all three, including release agents designed to be compatible with in-mould coatings and paintable release grades, so the interface between products is solved by one technical team."}],"troubleshooting":[{"title":"PU shade varies from block to block or shot to shot","family":"PU colorants","question":"Why does the colour of my PU foam or moulded part vary from one block, shot or batch to the next?","shortAnswer":"In most plants shade drift is a process problem before it is a pigment problem. The usual causes are colorant dosing that is not held constant (pump calibration, temperature-driven viscosity change, settled colorant in the day tank), changes in polyol or catalyst, and different reaction temperatures. Measure first, then change one variable at a time.","url":"https://www.chemieproducts.com/troubleshooting/pu-foam-shade-varies-between-batches"},{"title":"Colorant has settled or hard-packed in the drum","family":"PU colorants","question":"Why has my PU colorant settled, separated or turned into a hard cake at the bottom of the drum?","shortAnswer":"Settling is physical separation of the pigment dispersion. Heavy inorganic pigments settle fastest. Soft sediment can be re-dispersed by thorough mixing, but a hard cake means the dispersion has changed and the batch should not be used for colour-critical work. Rotate stock first-in first-out, agitate before use and never thin the colorant to loosen it.","url":"https://www.chemieproducts.com/troubleshooting/pu-colorant-settled-or-hardened-in-drum"},{"title":"Dark or brown core in slabstock foam (scorch)","family":"PU colorants","question":"Why is the core of my slabstock foam block darker or browner than the outside, and can the colorant fix it?","shortAnswer":"This is scorch: the reaction heat in the middle of a large block is high enough to degrade the polymer and some pigments. A colorant cannot cure a formulation scorch problem, but the right pigment choice stops it being made worse or more visible. Pastels and whites show it first. Tell your supplier the block size and water level so heat-stable pigments are specified.","url":"https://www.chemieproducts.com/troubleshooting/slabstock-foam-scorch-core-discolouration"},{"title":"Foam collapses, splits or changes density after adding colorant","family":"PU colorants","question":"Why did my PU foam collapse, split or come out at a different density after I introduced a new colorant?","shortAnswer":"A colorant is not inert. It carries moisture, carrier and pigment that can interact with surfactant and catalysts. Moisture above about 0.2 % adds blowing water, an incompatible carrier upsets the silicone surfactant, and some pigments adsorb amine catalyst. Test any new colorant at its working dose against a carrier-only blank before scaling up.","url":"https://www.chemieproducts.com/troubleshooting/foam-collapse-or-cell-defects-after-adding-colorant"},{"title":"Coloured specks, streaks or marbling in the PU part","family":"PU colorants","question":"Why do I see coloured specks, streaks or marbling in my polyurethane parts?","shortAnswer":"Specks are undispersed pigment agglomerates. Streaks and marbling are incomplete mixing of colorant into polyol. Check the colorant fineness of grind first, then the mixing and filtration on your machine, then colour changeover.","url":"https://www.chemieproducts.com/troubleshooting/coloured-specks-streaks-or-marbling-in-pu"},{"title":"PU yellows or fades in sunlight","family":"PU colorants","question":"Why does my coloured polyurethane part yellow or fade when it is exposed to sunlight?","shortAnswer":"Aromatic polyurethanes (TDI and MDI based) yellow under UV whatever the pigment, and some organic pigments fade on their own. Whites and pastels show it most. Fix it with light-fast pigments, a UV-stable lacquer or in-mould coating carrying UV absorbers and HALS, or an aliphatic system for demanding exterior use.","url":"https://www.chemieproducts.com/troubleshooting/pu-colour-yellowing-or-fading-in-sunlight"},{"title":"Colour bleeds or migrates into adjacent materials","family":"PU colorants","question":"Why is colour from my PU part bleeding or migrating into PVC, fabric, paint or adhesive it touches?","shortAnswer":"Migration happens when soluble dyes, or pigments with soluble fractions, move into the contacting material, helped by plasticisers, heat, humidity and pressure. Use insoluble pigments, avoid dyes where contact with PVC, fabric or white laminates is expected, and run a contact test under conditions agreed with your customer.","url":"https://www.chemieproducts.com/troubleshooting/pu-colour-bleeding-or-migrating-into-other-materials"},{"title":"Colour matches the swatch in one light but not another","family":"PU colorants","question":"Why does my PU part match the approved swatch in the lab but not under shop, showroom or outdoor light?","shortAnswer":"This is metamerism: two colours made from different pigment combinations can match under one light source and differ under another. Approve against a physical standard under at least daylight (D65), a store light (TL84) and incandescent (A), and match on the real substrate and gloss, not on a different material.","url":"https://www.chemieproducts.com/troubleshooting/pu-colour-matches-in-lab-but-not-in-store-metamerism"},{"title":"Colorant dosing is inaccurate or pumps wear quickly","family":"PU colorants","question":"Why is my colorant dosing inaccurate, and why are my dosing pumps wearing out?","shortAnswer":"Dosing error comes from viscosity swings, air in the line, abrasive pigments wearing soft parts, and very small volumetric doses. Check dosing by weight at working temperature, bleed air, use hardened wear parts for abrasive colours, and ask for a dosing colour engineered for your machine type.","url":"https://www.chemieproducts.com/troubleshooting/colorant-dosing-inaccurate-or-pump-wear"},{"title":"Parts stick to the mould or tear on demoulding","family":"Mould release agents","question":"Why are my PU parts sticking to the mould or tearing when I demould them?","shortAnswer":"Sticking means the release film is missing, too thin, still wet, or the wrong chemistry for your system and mould. Check mould temperature, flash-off time and the condition of the mould surface before changing product. Spraying more rarely fixes it and usually causes build-up.","url":"https://www.chemieproducts.com/troubleshooting/pu-parts-sticking-or-tearing-at-demould"},{"title":"Residue builds up on moulds","family":"Mould release agents","question":"Why is residue building up on my PU moulds and how often should I clean them?","shortAnswer":"Build-up is the non-volatile fraction of the release agent plus PU dust and flash. Over-application speeds it up. It dulls the surface, blurs texture and later causes sticking and paint defects. Spray thin and even, and clean on a cycle-count schedule with a cleaner suited to the mould material. Epoxy moulds can be attacked by aggressive solvents.","url":"https://www.chemieproducts.com/troubleshooting/residue-build-up-on-pu-moulds"},{"title":"Paint, lacquer or adhesive will not stick to moulded PU","family":"Mould release agents","question":"Why will paint, lacquer or adhesive not stick to my moulded polyurethane parts?","shortAnswer":"Almost always the cause is surface contamination from release agent, above all silicone, transferring to the part. Use paintable, non-silicone release grades, confirm contamination with a water-break or dyne test, and keep silicone sprays out of the production area altogether.","url":"https://www.chemieproducts.com/troubleshooting/paint-lacquer-or-adhesive-will-not-stick-to-moulded-pu"},{"title":"Pinholes, blisters or bubbles on the skin of moulded PU","family":"Mould release agents","question":"Why do I get pinholes, blisters or bubbles on the surface of integral skin or moulded PU?","shortAnswer":"Isocyanate reacts with water to make CO₂. If water sits at the skin surface, from a water-based release agent that has not flashed off, a damp or cold mould, or moist polyol and colorant, it forms gas bubbles right at the skin. Fully dry the mould, hold the correct mould temperature, apply a thin film and control raw-material moisture.","url":"https://www.chemieproducts.com/troubleshooting/pinholes-blisters-and-bubbles-on-integral-skin-pu"},{"title":"In-mould coating peels or delaminates from the PU part","family":"In-mould coatings","question":"Why is my in-mould coating peeling or delaminating from the polyurethane part?","shortAnswer":"Adhesion fails when something stands between the coating and the PU. The usual culprits are release agent that is excessive or not coating-compatible, a coating film poured too early (still wet) or too late (fully dried), wrong mould temperature, silicone contamination, or a coating not matched to the PU. Validate the pairing of release agent, coating and PU first.","url":"https://www.chemieproducts.com/troubleshooting/in-mould-coating-peeling-or-delaminating-from-pu"},{"title":"In-mould coating shows orange peel, craters, wrinkles or white haze","family":"In-mould coatings","question":"Why does my in-mould coating show orange peel, craters, wrinkles, pinholes or a white haze?","shortAnswer":"These are spray and solvent problems. Too thick or wet a film wrinkles, too little flash-off pops solvent into pinholes, oil or water in compressed air makes craters (fisheyes), poor atomisation gives orange peel, and a fast thinner in cool humid conditions causes blushing. Fix the spray set-up and match the thinner to conditions.","url":"https://www.chemieproducts.com/troubleshooting/in-mould-coating-orange-peel-craters-wrinkles-or-blushing"},{"title":"Coating cracks when the part flexes","family":"In-mould coatings","question":"Why does the in-mould coating or lacquer crack when my PU part is flexed?","shortAnswer":"The coating is less flexible than the PU beneath it, or it is too thick, or the part is flexed cold. Match coating elongation and hardness to the flex demand of the part: footwear soles need a flexible film, while a steering wheel or armrest can take a harder one. Chemie coatings are adjustable for tensile strength and abrasion resistance.","url":"https://www.chemieproducts.com/troubleshooting/in-mould-coating-cracks-when-the-part-flexes"}],"humanReadable":{"profile":"https://www.chemieproducts.com/supplier-profile","llms":"https://www.chemieproducts.com/llms.txt","llmsFull":"https://www.chemieproducts.com/llms-full.txt"}}
