High-Temperature Silicone Sealant

TREMPRO® 644 High Temperature Silicone Sealant is a one-part, ready-to-use silicone sealant. It has a paste-like consistency and cures to silicone rubber at room temperature.

Basic Uses

• The paste-like consistency of TREMPRO 644 High Temperature Sealant is easily gunnable and can be applied to vertical and overhead surfaces where the use of pourable self-leveling sealants would not be practical.
• This silicone sealant may be used in thicknesses up to 1/4" (6 mm) for bonding and sealing, joining metals and plastics, and electrical insulation.
• High-temperature situations, such as fireplace frames.
• Sealing joints between most non-porous materials such as glass, aluminum, metal and metal alloys.
