Akfix HT300 High Temp Silicone Gasket Maker, Red 10.1 fl oz-6 Pack

Akfix HT300 High Temp Silicone Red Gasket Maker is a high-performance silicone sealant developed for sealing, bonding, and repairing works where heat resistance is required. The high-temperature sealant reacts with atmospheric moisture to produce a tough, elastic silicone, making the gasket maker ideal for high-temperature construction applications.

• Excellent Heat Resistance: Withstands up to 250°C permanently and up to 300°C temporarily.
• 100% Silicone: Provides durability and flexibility.
• Temperature Flexibility: Remains flexible at low (-40°C) and high (+250°C) temperatures.
• Mechanical Resistance: Resists mechanical enforcement after curing.
• Acetoxy Cure: RTV silicone that is reliable and effective.
• Durable: Will not crack, shrink, or become brittle.
