Vinyl MDT Silicone Resin
Silico® Vinyl MDT Silicone Resin is a high-performance polymer made from M, D, and T siloxane units with vinyl groups. Its 3D network offers excellent flexibility, heat resistance, adhesion, and strength. Suitable for thermal, UV, and hydrosilylation curing in industrial and electronic applications.
Product Overview
Silico® Vinyl MDT Silicone Resin is a high-performance organopolysiloxane material synthesized from M (monofunctional), D (difunctional), and T (trifunctional) siloxane units with pendant vinyl groups. This controlled M–D–T network structure forms a highly crosslinked 3D polymer architecture, delivering an optimal balance of flexibility, heat resistance, adhesion, and mechanical strength.
Designed for demanding industrial and electronic applications, Silico® Vinyl MDT Resin supports thermal curing, hydrosilylation, and UV-curable systems, making it ideal for advanced formulations requiring both process versatility and long-term reliability.
