Primary Characteristics

Red spreadable

Condensation cure

Extreme high temp

Useful to 260°C
(500°F)

Primer required

Use for:
Aerospace applications such as potting, encapsulating,
coating and cushioning

Excellent for potting and encapsulating electric motors, transformers, and surge protection. Can be used in aerospace applications such as sealing, bonding and quaketing on vertical or overhead surfaces. Composition is free of solvents and solvent odour. Excellent retention of elastomeric properties at temperatures from -54°C to 260°C (-65°F to 500°F) continuously, and up to 316°C (600°F) for short periods of time. This two part silicone is supplied with a curing agent. Silicone primer is required. Cures at room temperature and has excellent adhesion qualities. The product comes complete with catalyst DBT. Specialized catalysts are avialable upon request.
