Overview RTV silicone sealant has proven itself as an outstanding sealing material
due to its:

  • Heat resistance (up to 500°F)
  • Low temperature flexibility (down to -75°F)
  • Elasticity
  • Vibration resistance
  • UV stability

Applications range from simple gap sealants to electronic encapsulants and room-temperature-molded solid silicone seals.

Important market segments include military, aerospace, transportation, electronics, construction, and consumer products.

Numerous RTV silicone grades offer compliance with UL, FDA, military, and private OEM specifications.

One-Part Systems vs. Two-Part Systems

One-Part Silicone Sealant

One-part silicone sealants are the easiest to use, requiring no weighing or mixing.

Two-Part Silicone Sealant

Two-part systems require accurate measuring and thorough mixing.

Cure Technologies for Silicone Sealants

Two different cure technologies are available for silicone sealants.

  • Condensation cure relies upon atmospheric moisture to catalyze the curing reaction and a byproduct is volatilized as the reaction proceeds.

  • Addition cure is not reliant upon atmospheric moisture and does not generate any byproducts. The addition cure produces virtually no shrinkage. For these reasons, the addition cure is preferred for molded applications. A drawback of the addition cure is its susceptibility to cure inhibition.
