PMHS is a silicone fluid that can be widely used as a release agent in the rubber and plastic industry. The product is an anti-rust agent for metal and an anti-adhesive agent for paper and packing material.

PMHS can increase the performance of tear strength, abrasion resistance, crease-resist, anti-fouling, waterproof, and ironing resistance without influencing the original breathability of the fabric. The optical glass coated with it will have high light transmittance and excellent mildew, and moisture resistance.

With the action of a metal salt catalyst, PMHS can form a durable waterproof membrane with good hydrophobic and high contact angle.
