SiliXan U – isocyanate free silicon cross-linking urethane compounds


Formulation of high abrasion resistant clear coat and paints with good chemical stability

The product class SiliXan U comprehends high quality binders for the formulation of highly abrasion-resistant lacquers and paints with good abrasion and chemical resistance. It is an UV stable urethane to bear the silicon groups which react with humidity at room temperature or which are forced at temperature of 60 ° C to 180 ° C to form a glass network. The SiliXan U products are free of toxic or unsafe isocyanates and contain as raw material no nanoparticles. After the application the contained "silane heads" react to nano-scaled SiO2 domains, which give rise to a high hardness and excellent wear resistance. These novel binders are suited to formulate highly transparent high-solid or solvent-based clear coats that can NOT be scratched with steel wool. The excellent property profile of the SiliXan U products leads to following application fields:

Mode of action of SiliXan U

EN Reaktion SX U Large
  • Formulation of high quality clear coats with high abrasion resistance and excellent chemical resistance
    • - temperature curing stove coatings (baking enamel)
    • - at room temperature moisture cross-linking systems
  • Improvement of the properties of 2K-PU systems
  • Combination with epoxide or melamine resin coatings
  • Increase of the mechanical resistance of silicone resin systems

A colouring of the SiliXan U binder is possible with standard colour pigments or dispersions. The silane heads of the urethane backbone stabilize in particular inorganic colour pigments very well and hence in SiliXan U based formulations to a large extent the requirement of interfering dispersing additives is reduced. Out of SiliXan U binders and corresponding inert inorganic pigments colour formulations can be developed, which are chalking and discoloration stable over thousands of hours in the Xeno weathering test.
