Applications
General Information
It is a kind of n-butylamino group silane coupling agent. It is the most recommended silane for endcapping Polyurethanes which can fast react with free NCO group and lead to colorless low-viscosity PU prepolymers with improved UV stability and reduced yellowing tendency of sealants. It does not contain toxic aniline and does not release NCO during application.
Suitable Polymers
Epoxy, Urethane, Polyurethane(PU), PA, PBT, EVA, modified PP, Silicone, etc.
Compatible Polymers and Resins
  • Epoxies (EP)
  • Ethylene Vinyl Acetate (EVA)
  • Polybutylene Terephthalate (PBT)
  • Polyurethanes (PU)
  • Silicones
