Silane HENGDA-E8166 is versatile amino functional coupling agents used a broad range of applications to provide superior bonds between inorganic substrates and organic polymers. The secondary amine function reacts with a wide array of thermoset, thermoplastic and elastomeric materials.
Silane-endcapped Polyurethanes: Silane-terminated polyurethanes can be prepared by reacting traditional NCO-terminated urethane prepolymers with HENGDA-E8166. It can react very fast with free isocyanate groups and lead to a high converted silane-endcapped product. Side reactions can be significantly reduced. It is the most recommended silane for endcapping Polyurethanes. It leads to colorless low-viscosity PU prepolymers with improved UV stability and reduced yellowing tendency of sealants. Another benefit of HENGDA-E8166 is that it does not contain traces of toxic aniline. Examples of applications where HENGDA-E8166 used include polyurethanes for structural adhesives, parquet adhesives and over-paintable hybrid sealant.
Glass fiber/glass fabric composites: As a finish or size constituent.
Mineral fiber insulating materials and abrasives: As an additive to phenolic resin binders.
Foundry resins: As an additive to phenolic, furan and melamine resins.
Sealants and adhesives: As a primer or additive and for chemical modification.
Mineral-filled polymers (composites) or HFFR cables: For pretreatment of fillers and pigments.
Paints and coatings: As an additive and primer for improving adhesion to the substrate.
