Bostik FR Acrylic Sealant is a 1-component fire resistant sealant based on acrylic dispersion.

Bostik FR Acrylic Sealant is a plastoelastic sealant which is slightly intumescent above +120°C and is suitable for up to 4 hours of fire resistant sealing of linear joints.

Application
Bostik FR Acrylic Sealant was specifically developed for fire resistant sealing of linear connection joints in gypsum and stony substrates.
Fire resistance tested according to EN 1366-4 up to +120 minutes in a 20 mm wide gap.
Combined with FP PU Foam up to 180 minutes in a gap of 30 mm wide.
Ensure that you choose the correct fire resistance for your application by consulting the classification and test reports.

Directions of use
A joint with the correct dimensions is able to absorb movements between building materials. The joint depth should always be in the correct relationship of the joint width.
A general rule is the ratio of joint depth to the width of the joint with a joint width up to 10 mm is 1:1, with a minimum of 5 mm in width and depth. For joints wider than 10 mm, the depth is the width divided by 3 plus 6 mm.

Limitations
Not suitable for PE, PP, PC, PMMA, PTFE, soft plastics, neoprene and bituminous substrates
Not suitable for continuous exposure to water.

Paintability
FP Acrylic Sealant is paintable when fully dry.
During curing product will show shrinkage, which can cause cracking of the paint. We recommend testing compatibility with paint prior to application.

Cleaning
Tools should be cleaned after use with water. Hands can be cleaned with Bostik Wipes and/or water and soap.
