Foster® 95-50™ Flextra® Sealant is primarily used with low temperature insulation to prevent the migration of water and water vapor into the insulation system via butt joints.
Flextra Sealant is also recommended as a bedding compound for the installation of cellular glass insulation. In this application, it protects both the insulation from abrasion and metal surfaces from corrosion.
Flextra Sealant is supplied in a special “buttery” consistency, which facilitates application to insulation surfaces without stringing or excessive drag. It may be applied at temperatures as low as 50°F (10°C) without difficulty.
Flextra Sealant contains no asbestos, lead, mercury, or mercury compounds.
