FM365
B3 Expanding Foam Max
FM365 is a rapid curing, high yield, one component gun grade expanding polyurethane foam that is suitable for general gap filling, bonding and insulation applications.
Usage/Purpose
For Interior and Exterior Use
FM365 is a rapid curing, high yield, one component gun grade expanding polyurethane foam that is suitable for general gap filling, bonding and insulation applications. Applications include the perimeter sealing and fixing of windows and doors, insulation panels and non fire rated pipe penetrations.
Massive 40 litre yield from only 540ml product.
Features a dual use cap so can be both gun and nozzle applied.
- Ideal for filling, sealing and insulating of joints and gaps in a variety of building and construction applications
- High yield application – joint only requires filling to 60%, prior to post-expansion
- Rapid cure formulation – foam is tack free within 8 minutes, and can be cut or trimmed within 45 minutes
- Forms a strong bond to concrete, brickwork, stone, plaster, wood, fibre concrete, metal, PVC and polystyrene
Preparation
- Always carry out a test to confirm compatibility prior to use.
- Protect floor coverings with paper or a plastic film.
- Remove all loose particles, dust and grease.
- A speedier cure can be attained by moistening the substrates if needed.
Usage Guidelines
- Shake the canister vigorously at least 20 times. Remove the protective cap and screw the gun carefully onto the canister.
- Invert can and direct nozzle into gap, pressing gently on the trigger to establish the correct flow rate.
- Joints should be underfilled to allow for post expansion of the foam. Fill to approximately 60% of joint depth for optimum results.
- For best results always work with the canister in a vertical position and keep the valve pointed downwards.
- On horizontal surfaces, always work away from the exuded bead and on vertical applications, start at the bottom, working upwards.
- On deep joints, apply in layers, waiting until each layer has skinned and partially cured before applying the next.
- Applying a light misting of clean water before applying each layer before subsequent application will assist adhesion and cure speed.
Health + Safety Precautions
Safety data sheet must be read and understood before use.Extremely flammable - keep away from open flames and other ignition sources.
