DYNASYLAN® SIVO 280 (VPS SIVO 280)

DYNASYLAN® SIVO 280 (VPS SIVO 280) is a novel multifunctional siloxane adhesion promoter with aminofunctionalities that can be used for various applications. It exhibits excellent wetting on substrates and can form weather- and moisture-resistant bonds to substrates which are partially difficult to adhere. The main benefits of DYNASYLAN® SIVO 280 in silylated polyurethane or MS polymer based formulations are improved adhesion to plastics, especially to polymethylmethacrylate (PMMA) and aluminum, well-balanced mechanical properties and significant VOC-reduction compared to conventional amino silanes. DYNASYLAN® SIVO 280 is considered primarily as an additive in moisture curable formulations to eliminate the need for special primers in numerous bonding applications. Loading levels of 0.5 to 2.0 wt. % of DYNASYLAN® SIVO 280 as an additive - calculated on the overall formulation - are typically recommended.
