Silicone Coated Fiberglass cloth is made of a woven fiberglass substrate that has been coated on one or both sides with silicone rubber. Suntex offers dimensional stability, durability, excellent tensile strength and low elongation. The product surface friction is much higher than that provided by fabrics coated with PTFE, yet allows the user to maintain comparable release characteristics. In fact, some of the products that may be present on a PTFE coated fabric may not be present on a silicon coated surface. Choose from one of Suntex's range of colors to use where an excellent surface grip release is desired.
