Fire Rate Acrylic Sealant

Kryfix Fire Rate Acrylic is a water-based acrylic sealant suitable expansion joints and penetrations requiring a fire-resistant seal. Kryfix Fire Rate Acrylic expands when exposed to fire to form an inorganic plug in joints and voids, assisting in preventing fire transmission across partitions in a building. Kryfix Fire Rate Acrylic combines exceptional UV and water resistance with outstanding flexibility, non-slump properties and ease of application, making it ideal for internal and external applications.

Uses

• Interior & exterior joints between substrates and construction elements including concrete, plasterboard, blockwork, fibre cement, Hebel block, speed panel and brick walls.
• Building services’ penetrations pipes, cable trays, conduits, and ducts

Application

• For best results, Kryfix Fire Rate Acrylic should be applied at temperatures between 5°C and 35°C
• Cut the end of the sausage and place the sausage barrel gun nozzle over the sausage’s cut end
• Place the sausage into the sausage barrel gun’s housing and screw the nozzle head onto the housing of the barrel.
• Install a suitably sized backing rod to fit the joint width to be sealed/caulked
• Gun Kryfix Fire Rate Acrylic into the joint space, facing the gun tip forward to ensure complete joint filling such that no voids are present, which would weaken the strength of the joint
• Finish tooling the joint within 15 minutes and immediately wipe up excess material with a damp cloth.
• Protect from water/rain until suitably cured
