Introduction
Description
LA-3550 is mono-end, polyhydroxy-modified organosilicone polymer. It combines the characteristic tactile properties and water/graffiti-repellent functions of organosilicones with excellent compatibility with various polyurethane and amino-based resin systems. The terminal hydroxyl groups can participate in crosslinking reactions with the resin matrix, effectively incorporating organosilicone components—particularly at the surface—to significantly enhance resin performance, including weather resistance, low-temperature resistance, water and stain resistance, and surface feel.
Chemical Composition
Multi-modified polysiloxane
Application suggestion
Durable tactile feel: 0.2–1%
Water resistance: 1–5%
Stain resistance: 2–6%
Resin modification: 1–6%
Application method
Can be incorporated as a silicone modifier during the polymerization process; it can also be added directly to two-component polyester, polyurethane, or acrylate systems.
Applicable coating systems
Oil-based system
Solvent-free system
