Applications

FEATURES

One-component adhesive/sealant
Cures at room temperature when exposed to moisture in the air
Alkoxy cure system
Non-sag, paste consistency
Easy to apply
Cures to a tough, flexible rubber
Excellent adhesion to many substrates
Stable and flexible from -40°C (-40°F) to +180°C (+356°F)

APPLICATIONS

Designed for applications which demand a strong but flexible bond, such as when bonding materials with differing thermal expansion rates, e.g. glass to metal or glass to plastic.
Unprimed adhesion to commonly used materials including enamelled and painted steel, aluminum, ceramic and glass as well as to certain plastics used in engineering applications.
Used as a Formed-in-Place Gasket (FIPG) material.

Advantages

  • Neutral curing system
  • Resistance against UV radiation exposure for a long while
