ETERNACOLL® UH200 is a solvent-free solid aliphatic polycarbonate diol. Provides high chemical resistance, excellent hydrolytic stability, high thermal stability as well as high mechanical properties. Exhibits higher gloss, enhanced hydrolysis resistance, improved scratch as well as abrasion resistance. Offers better adhesion to metal even after weathering and better corrosion resistance by replacing the blend of a classical polyol by this polycarbonate diol. Polyurethanes produced from ETERNACOLL® UH200 are superior to those based on polyether diol as well as polyester diol.

DAOTAN TW 6450/30WA is recommended as the NMP / NEP- free alternative for DAOTAN (V)TW 1236. Like the latter, DAOTAN TW 6450 is a polycarbonate-based, high molecular weight Polyurethane dispersion. Dried at ambient temperature, DAOTAN TW 6450 provides clear, crack-free films without further addition of organic solvents or additives. These films exhibit excellent elasticity and mechanical properties and very good adhesion to different plastic substrates like e.g. ABS, PC, PA, PVC, PC/PBT. Accordingly DAOTAN TW 6450/30WA is particularly recommended for waterborne plastic primer and waterborne auto OEM Basecoats with outstanding requirements regarding stone chip resistance properties. A further use is as modifier resin to improve stone chip resistance properties of e.g. auto OEM primer surfacer formulations. DAOTAN TW 6450/30WA can be used as an adhesive for pharmaceutical and food packaging applications. It provides excellent peel strength and long-term humidity resistance. It is ready to use; no further formulation is needed.

CYMEL® 385 resin is a methylated high imino melamine resin with a low degree of alkylation. Being supplied in water, it is recommended as a crosslinking agent for hydroxyl-containing emulsion polymers and other aqueous systems containing hydroxyl or amide functionality. CYMEL® 385 resin has a high tendency to self-condense and may be used to increase the hardness and resistance properties of thermoplastic waterborne polymers.

EPIKURE Curing Agent 3282 is a highly reactive, modified aliphatic amine adduct designed for rapid curing at room temperature. Ideal for tooling gel coats, laminating compounds, and adhesives, it delivers efficient performance across demanding applications.
