Professional grade low expansion, polyurethane gun foam
MEGAFOAM LOW EXPANSION GUN is high quality, self-expanding, one Äì component, ready to use polyurethane foam for professional use. It is fitted with a plastic adaptor head for use with a foam applicator gun. It has a minimal expansion after application (less than 50%) and is therefore very economical to use. It contains CFC-free propellants, which are completely harmless to the ozone layer.
ADVANTAGES
- Low post-expansion
- Excellent adhesion on most substrates
- High thermal and sound insulation
- Higher yield – Excellent filling capacities
- Excellent mounting capacities
- Excellent stability
- User and environment friendly
APPLICATIONS

Surface preparation
Moistening of the surfaces and the uncured foam with a water sprayer improves adhesion and curing speed.
Application
- Surfaces must be clean, free of dust and grease
- Wear suitable protective gloves
- Shake the can well for at least 30 seconds
- Fit the gun on the adapter
- Hold the can upside-down and extrude the foam by pressing the valve
- Gaps have to be filled partially up to 65% as the foam will expand
- Repeat shaking regularly during application
- If you have to work in layers repeat moistening after each layer
A suitability test is recommended
REMARKS
- Avoid contact with uncured foam after application especially at low temperatures.
- Cured PU foam must be protected from UV radiation by applying a top layer of PU or acrylic paint or sealant (silicone, acrylic, MS Polymer).
