In the electronics industry, optical devices, and specialty coatings, the wear resistance, transparency, and weatherability of material surfaces are often key factors determining product lifespan and performance. IOTA 950 Methyl Silicone Resin achieves a pencil hardness of ≥6H after full curing and a visible light transmittance of over 90%, combined with excellent high/low temperature resistance, water repellency, and wear resistance. It is an ideal choice for anti-flicker coatings on CRT anode caps and surface treatment of PMMA (acrylic) sheets.

Product Overview

IOTA 950 is a methyl silicone resin that forms a hard, transparent, wear-resistant protective coating after ambient surface drying followed by high-temperature curing. It is particularly suitable for surface treatment of thermosetting plastics and anti-flicker coatings for CRT anode caps in the electronics industry.
