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.

Beckopox EH 2162W is a hardener designed for water-reducible coatings on mineral and metallic substrates. It is particularly suitable for concrete coatings, offering lower viscosity and a longer pot-life compared to standard hardeners like Beckopox EH 623w, especially at lower VOC levels and when used with liquid epoxy resins.

EBECRYL® 246/20HEMA is a difunctional aliphatic urethane acrylate that does not contain intentionally added organic tin compounds, heavy metals or quinones. The resin is diluted in 20 parts HEMA. (Please note that quinones are present in many raw materials, so the overall quinone content is reduced, but not zero). Films of Ebecryl®246/20HEMA cured by electron beam (EB) or ultraviolet light (UV) exhibit excellent abrasion resistance, toughness and flexibility and are resistant to yellowing.

EBECRYL® 1365 is a hexa-functional silicone modified urethane acrylate diluted in 50% of EBECRYL® 160. EBECRYL® 1365 can be used to prepare UV/EB curable coatings with low surface energy providing anti-stain and easy-to-clean properties. Additionally EBECRYL® 1365 can be used as a processing agent in matt and excimer curable formulations, facilitating a uniform film creation which in turn significantly increases the process robustness.
