RTV Silicone Rubber - Industrial Grade Silicone Rubbers

LANCHEMIE RTV Silicone Rubber, available in one-component moisture-cure and two-component addition-cure grades, is the core material for high-performance industrial and specialty sealants. Its unique room-temperature curing capability eliminates the need for high-temperature vulcanization equipment, enabling flexible, efficient on-site installation and factory batch application.

In automotive manufacturing, it is widely used for engine bay gasketing, headlight housing sealing, and body seam sealing, withstanding long-term high-temperature vibration, oil corrosion, and harsh outdoor weathering, reliably preventing water and dust ingress for over 10 years of service life.

For electronics and new energy sectors, it serves as primer-free sealants for PCB assemblies, EV battery pack enclosures, and 5G communication components, delivering exceptional electrical insulation, moisture resistance, and electrolyte corrosion protection. It also excels in building curtain wall joint sealing, chemical pipeline flange gasketing, and food-grade sanitary waterproof sealing, fully compliant with global REACH, RoHS standards.
