OCI Silicone Sealant is a high-performance, one-part silicone adhesive and sealant manufactured by OCI International (Orgavyl Chemical Industries). It is widely used in residential, commercial, and industrial projects due to its excellent flexibility, strong adhesion, and high resistance to water, UV radiation, mold, and weather extremes.

OCI produces specialized formulas tailored to specific technical needs:

• OCI Orgasil 103 (Acetic Cure):A professional-grade, anti-fungus sealant. It releases a minor vinegar-like acetic acid odor while curing and is the premier choice for building glass aquariums or sealing high-moisture zones.
• OCI N-193 & N-192 (Neutral Cure):Odorless, non-corrosive formulas designed specifically for sensitive metals and masonry. They do not react with or damage metal surfaces. [
• OCI Hi-Temp RTV (Gasket Maker):Available in specialized variations like Grey RTV and Black RTV. These 100% silicone formulas create stable, "formed-in-place" gaskets that resist extreme temperatures up to 650°F (343°C), as well as intense vibrations, oils, and automotive grease.
