ASI 335 Neutral Cure Silicone Sealant/Adhesive has superior adhesion to difficult surfaces like chrome and stainless steel, porous surfaces and most plastics. Its a non-yellowing, one-part, non-slump, low odor neutral moisture-curing RTV (room temperature vulcanizing) that cures to form a tough, high modulus rubber with long-term flexibility and durability. ASI-335 is solvent free. The neutral curing mechanism of ASI 335 is ideally suited for use in confined work areas since no objectionable odors are evolved. ASI 335 neutral cure silicone has excellent resistance to weathering including ozone, ultraviolet radiation, freeze-thaw conditions and airborne chemicals. After cure, the wide heat stability range of ASI 335 is from -57°C to +204°C (-70°F to 400°F) and the sealant can be applied to surface temperatures from -18°C to +50°C (0°F to +120°F).


  • ASI 335 neutral cure silicone is a durable general-purpose sealant/adhesive in a wide range of applications.
  • Unprimed adhesion to a many types of substrates is achieved with the use of ASI 335. For example, ASI 335 neutral cure silicone adheres to unprimed chrome and stainless steel and glass where other high modulus silicone sealants would require to be primed.
  • As a formed-in-place gasket, ASI 335 exhibits low swell, low compression set and good oil resistance. These characteristics impart an unusual balance of properties to ASI 335 to prevent leakage in harsh environments such as engines, transmissions, water pumps, rear axles and oil pans.
