ASI 335 Neutral Cure Silicone, Clear, 10.2 fl. oz.


ASI 335 Neutral Cure Silicone Sealant/Adhesive is a one-part, non-slump, moisture-curing RTV (room temperature vulcanizing) that cures to form a tough, high modulus rubber with long-term flexibility and durability. The neutral curing mechanism of ASI 335 is ideally suited for use in confined work areas since no objectionable odors are evolved. The non-slump characteristics of ASI 335 allow application to vertical or horizontal joints without flowing or sagging. ASI 335 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).


  • 100% Silicone Sealant
  • High Performance, Excellent Adhesion
  • Resistant to UV degredation and Weathering
  • Mold and Mildew Resistant
  • Adheres to porous surfaces unlike other 100% silicones
  • Low odor, non corrosive to most metals
  • Low compression set and excellent oil resistance

Additional Benefits:

  • Contains No Solvents or Isocyanates which makes ASI 335 VOC Compliant
  • Easy to Dispense and work with at a Variety of Extreme Temperatures
  • Withstands a wide range of high heat and extreme cold
