Maintains elastic properties between -80 to 600°F

NuFlex Hi-Temp silicone is a one-part 100% silicone with a toothpaste-like consistency. It cures when it is exposed to moisture in the air to form a tough rubbery seal.

NuFlex® 302 HT was formulated to perform at temperatures ranging from –65°C to 260°C (-85°F to 500°F) under continuous operating conditions. During intermittent exposure, NuFlex® 302 HT will withstand temperatures as high as 316°C (600°F). It is ideal for a number of sealing and bonding applications.

IMPORTANT INFORMATION

Do not use in direct contact with fuels such as gasoline or diesel fuel.

NuFlex® 302 Hi-Temp is supplied ready-to-use. It flows readily from its container under pressure. The paste-like consistency makes it easy to work with; a spatula or wooden paddle can be used to tool the surface.

Tack-Free Time: Curing progresses inward from the surface. At conditions of 25°C (77°F) and 50% relative humidity, a tack-free skin forms within 10-20 minutes. Tooling should be completed immediately after application. If masking tape is used to mask an area, it must be removed before the tack-free skin forms.

Cure-Time: Cure time is affected by relative humidity, degree of confinement and cross-sectional thickness of the sealant. Sections up to 3.2 mm (1/8″) thick become rubbery solids in about 24 hours at room temperature and 50% relative humidity. In applications where NuFlex® 302 Hi-Temp may be partially or totally confined during cure, the time required for proper cure is generally lengthened by the degree of confinement. Every application involving confinement during cure should be thoroughly tested before production commences. Curing time increases with the thickness of the sealant. A 12.7 mm (1/2″) cross section for example, may require 3 or 4 days for complete cure. However, the cure will have penetrated the outer 3.2mm (1/8″) in about 24 hours.
