ASI 335



ASI 335 Neutral Cure RTV Silicone is a one-part, non-slump, moisture cure sealant/adhesive that cures to form a tough rubber with long-term flexibility and durability.

Due to the formulation, ASI 335 offers advanced adhesion to a variety of surfaces including porous substrates, vinyl, some plastics, fiberglass, metals, woods and more. ASI 335 emits a low odor which makes it ideal for confined work spaces or occupied areas. It is extremely resistant to UV degradation, yellowing, temperature extremes and most chemicals. It is a 100% RTV Silicone and will remain easy to dispense and tool even at cold temperatures. ASI 335 has excellent physical properties and will continue to perform long-term in a variety of applications.
