Oxime-cured Polydimethylsiloxane (PDMS) is a one-part, room-temperature vulcanizing (RTV) silicone elastomer. It cures by a neutral oxime condensation reaction, releasing ketoxime by-products during crosslinking. This chemistry provides a durable, flexible, and weather-resistant silicone rubber with strong adhesion to a wide range of construction and industrial substrates. Compared to acidic cure systems, oxime-cured PDMS is non-corrosive, making it particularly suitable for sensitive materials such as natural stone, glass, metals, and ceramics.
Applications
Construction and Façade Sealing → Weatherproofing of natural stone, glass, and metal panels
Industrial Assembly → Adhesion and sealing in electrical, automotive, and appliance components
Joint Sealant → Expansion joints in building structures requiring high flexibility
Protective Sealing → Waterproofing and UV protection in exterior applications
General Purpose Bonding → Substrates where non-corrosive curing is required
