Silicone Coating
category
Silicone coatings apply polydimethylsiloxane (PDMS) or addition-cure silicone rubber (LSR) at 20–300 g/m² via knife, gravure, or calendar methods, cured at 100–200°C for 1–5 minutes with platinum catalyst or peroxide systems. Surface energy of 20–25 mN/m provides excellent release properties and hydrophobicity (contact angle 100–120°). Temperature resistance from -60°C to +250°C continuous service exceeds all organic polymer coatings. Tensile strength of 4–8 MPa with elongation of 400–600%. Biocompatibility meets ISO 10993 for medical grade applications. Silicone-coated fabrics represent a $600 million global market for airbags, medical textiles, and industrial release liners.
Role
Specialized high-performance coating for automotive airbag fabrics, medical implantable textiles, food-grade conveyor belts, and industrial release sheets where biocompatibility, extreme temperature resistance, and non-stick surfaces are non-negotiable requirements.
