FR 300 Hybrid
Zettex FR300 is a high-quality and durable one-component fire-resistant adhesive based on MS Polymer, suitable for fire-resistant bonding of all kinds of surfaces in construction and industry. Zettex FR300 is also chemically resistant and permanently flexible. Zettex FR300 has a fire resistance of up to 4 hours. Zettex FR300 is paintable with most common paint systems. Testing is recommended.

​Application instructions
Suitable for the fire-resistant adhesion of connection and dilation joints in construction, that in the event of fire must have certain fire-resistance. The spread of fire, smoke or toxic vapours is counteracted. FR 300 is also certified for horizontal joints and connections to floor/ceiling with wall, wooden and steel casings and all stud applications. The fire-resistance is tested in conformity with EN 1366-4 to 240 minutes in a horizontal or vertical joint measuring 30 mm wide. Make sure of the correct fire-resistance for your applications by consulting the classification and test reports.

FR 300 is not suitable for PE, PP, PC, PMMA, PTFE, soft synthetics, neoprene and bituminous surfaces. The surfaces must be clean, dry and free of grease and dust. Neither may there be any old sealant residues on the surface. Although the FR 300 adheres excellently to most common surfaces it is recommended to first carry out a test. A primer may first be applied for optimal adhesion to some surfaces. Residues that have not properly hardened can be removed with Zettex Profireiniger. Smooth using Zettex Easyfinish within 10 minutes because of skin formation. FR 300 can also be painted over with most water and oil based paints. It is advised to test the tolerance of the paint beforehand. Hands can finally be cleaned with the Zettex Cleaning Wipes
