In modern industrial manufacturing, sealants are widely used for bonding and sealing electronic and electrical components. Gasket sealing plays a crucial role in protecting internal electronic components by preventing the ingress of dust, moisture, and corrosive substances, thus avoiding damage to precision components.
Gasket sealing technology is an essential part of industrial manufacturing. While traditional rubber gaskets and CIPG (Cured-In-Place Gasket) applications are already widely adopted, the increasing demands for production efficiency and performance have made UV-CIPG (UV-curable Cured-In-Place Gasket technology) the leading choice in modern industrial sealing solutions.
UV-CIPG technology involves dispensing liquid sealant onto the surface of a product’s substrate using automated equipment, which is then rapidly cured under UV light to form an elastic gasket. Compared to traditional rubber gaskets, UV-CIPG offers a comprehensive upgrade—from automated production to precise sealing—meeting the demands of modern industry for efficiency, reliability, and environmental sustainability.
SIL-MORE introduces UV-SIL CIPG 477-V4, a high compression resilience, reworkable, highly stretchable waterproof UV-curable resin specifically designed for portable precision electronic products. The resin is dispensed into the grooves of housing substrates (such as metal, PVC, ABS, and PC) and quickly cured under UV light, providing a waterproof sealing solution that replaces traditional rubber gaskets. This material exhibits high compressibility and maintains excellent resilience even after prolonged screw fastening, effectively resisting underwater pressure for superior waterproof performance.
