Expansion of LANXESS’ Trixene Aqua BI product family. Excellent crosslinkers and adhesion promoters for aqueous coatings systems.

Specialty chemicals company LANXESS expands its unique Trixene Aqua range of water-based blocked isocyanate dispersions. The product family now includes new grades, specifically designed to expand the application areas and meet more demanding customer needs.

As a non-ionic product, Trixene Aqua BI 522 is designed to achieve harder coating, with superior chemical resistance and good drying characteristics. It is applied to metal and glass surfaces. Glasses, for example, are given excellent durability by this coating agent.

Trixene Aqua BI 202 is born by LANXESS’ continuous focus on fibre sizing technologies, whereas the formulator can benefit from its combination with Witcobond polyurethane dispersions. The use of Aqua BI 202 can improve strength of the chopped glass strands and impart composites higher mechanical, flexural properties, as well as improve impact resistance. Glass fibers are used for the formulation of high performance engineering plastics, e.g. polyamide- and PBT-based composites. Such glass-fiber reinforced plastics are indispensable in the automotive and civil engineering industries, among others.

Excellent cross-linking in aqueous systems

The Trixene Aqua products are excellent crosslinkers and adhesion promoters for aqueous coatings systems. They boost the chemical and mechanical resistance of coatings and sizing formulations to allow much better performance and durability in the final application. Due to the blocked isocyanate group they are more stable than the respective free counterparts and can easily be formulated in 1-K and 2-K systems together with a variety of complementary aqueous resins, e.g. hydroxyl-functional acrylics, polyesters and urethanes.
