Features & Benefits
- Ready-to-Use Product Features
- Features & Benefits
- Excellent adhesion & filling capacity and high thermal & acoustical insulation value.
- Low expansion, low pressure rates.
- Adheres to almost all building materials with the exception of surfaces such as polyethylene, Teflon, silicone and surfaces contaminated with oils and greases, mold release agents and similar materials.
- Mold-proof, water-proof, over paintable.
- Cured foam dries rigid and can be trimmed, shaped and sanded.
Applications & Uses
- Applications
- Application Area
- Compatible Substrates & Surfaces
- Cure Method
- Applications
- Fixing and insulating of door and window frames.
- Filling and sealing gaps, joints and cavities.
- Filling of penetrations in walls.
- Insulating electrical outlets and water pipes.
- Instructions
- Optimal can temperature is 20°C. Application (ambient) temperature is between -5°C to 30°C.
- Shake the can well before use. Screw the adapter on the valve.
- Hold the can upside down and activate the foam by pressing the valve.
- Moisturizing the surfaces and the foam improves adhesion and shortens curing time.
- Fresh foam can be cleaned by Akfix Foam Cleaner. Cured foam can be cleaned barely mechanically.
- Restrictions
- Storage above 25°C and below 5°C shortens shelf life.
- Should be stored and transported in vertical position.
- Should be kept in room temperature for at least 12 hours before the application.
- Cured foam will discolor if exposed to ultraviolet light.
- Paint or coat the cured foam for best results in outdoor applications.
- Lower temperatures decrease yield and curing time.
