IOTA LSR 3352: High-Strength, Solvent-Free Silicone Coating for Superior Fireproof Fabrics
Looking for a reliable, high-performance silicone coating specifically engineered for fireproof fabrics? Meet IOTA LSR 3352, a platinum-catalyzed, addition-cure liquid silicone rubber designed to deliver exceptional strength and adhesion without solvents.
IOTA LSR 3352 stands out with its excellent fluidity, enabling smooth, solvent-free coating applications. Its low initial viscosity ensures easy processing via blade coating or dipping, making it ideal for impregnating or coating fiberglass fabrics and other industrial textiles. The cured material exhibits remarkable mechanical properties, including a Shore A hardness of 40, a tensile strength of 5.5 MPa, an elongation at break of 250%, and a high tear strength of 13 kN/m. These characteristics translate into durable, flexible, and resilient finished fabrics capable of withstanding demanding conditions.
A key advantage is its dedicated two-component system (mixed at a precise 1:10 weight ratio, A:B). The A component contains the platinum catalyst, requiring careful handling to avoid catalyst poisoning from contaminants. For coloring, pigments must be added exclusively to the B component before mixing. Available in convenient packaging options (A: 10kg, B: 20kg or 200kg), it offers a shelf life of 12 months when stored unopened below 23°C.
Choose IOTA LSR 3352 for your fireproof fabric production. It combines ease of application, robust final properties, and strong substrate adhesion for superior, safer products.
