Cilbond® 49SF is a single-component bonding agent specifically designed for hot-cure applications (more than 160°F/70°C) with castable polyurethane elastomers and injection-molded TPU systems. It features a pigmented red color and is widely recognized as the industry benchmark for high-performance urethane bonding. Cilbond® 49SF has been developed to bond effectively with various materials, including metals, polyesters, polyamides, epoxies, and fiberglass reinforced plastics. It is highly recommended by leading urethane manufacturers and offers impressive in-service heat resistance of up to 265°F/130˚C (or up to 350°F/180˚C when used in combination with the Cilcure® B additive).
