Momentive RTV630-1LB Two-Part Silicone Rubber Compound 1 lb Kit

Momentive RTV630-1LB is a two-part silicone rubber compound designed for molding, potting, encapsulation, and prototype tooling applications. Part of the SILTRUST™ family of silicone materials, RTV630 cures at room temperature to form a durable, high-strength silicone elastomer with excellent tear resistance, low shrinkage, and outstanding reproduction of fine detail.

Key Features & Benefits

  • Two-part RTV silicone rubber compound
  • Convenient 10:1 mix ratio by weight
  • Room-temperature curing system
  • High-strength silicone elastomer after cure
  • Excellent tear resistance and durability
  • Low shrinkage for accurate mold reproduction
  • Suitable for potting, encapsulation, and tooling applications
  • Can be heat accelerated for faster curing

Product Description

Momentive RTV630 Silicone Rubber Compound is engineered for demanding industrial, aerospace, and electronics applications requiring a tough, flexible silicone elastomer. The two-component system consists of RTV630A and RTV630B, which combine in a 10:1 ratio and cure at room temperature without generating excessive heat or shrinkage.

Once cured, RTV630 provides excellent mechanical properties, including high tear strength, good elongation, and reliable performance across a broad temperature range. Its self-leveling characteristics make it well suited for mold making, electrical potting, encapsulation, prototype tooling, vibration isolation, and component protection. The cured silicone maintains flexibility and durability in challenging environments while accurately reproducing fine surface details.

Typical Applications

  • Electrical Potting
  • Electronic Encapsulation
  • Prototype Tooling
  • Mold Making
  • Vibration Isolation
  • Component Protection
  • Aerospace Applications
  • Industrial Manufacturing
