Description
MEGAFOAM B2 FIRESTOP GUN is a one-component, fire retardant, low expansion, ready-to-use polyurethane foam with excellent thermal and sound insulation properties. After curing, the foam can be trimmed and sanded. It has minimal expansion after application, making it very economical to use. It is designed for use with a professional foam applicator gun and classified as B2 according to DIN 4102.
ADVANTAGES
- Flame retardant – B2 Class
- Low expansion after application

Instructions for use
Surface preparation
Moistening the surfaces with a water sprayer improves adhesion and curing speed.
Application
- Surfaces must be clean, free of dust and grease.
- Shake the can well for at least 30 seconds.
- Fit the application gun on the adapter.
- Hold the can upside-down and extrude the foam by pressing the trigger.
- Fill gaps partially up to 65% as the foam will expand.
- Protect cured foam from sunlight exposure after application.
Caution: Product suitability testing is recommended.
REMARKS
- Avoid contact with uncured foam after application, especially at low temperatures.
- Cured PU foam must be protected from UV radiation and high temperatures.
- Before use, all MEGAFOAM PU foams should be stored at room temperature for at least 12 hours.
CLEANING
Fresh foam can be removed with GUN & FOAM CLEANER or acetone. Proper cleaning of the gun after each use ensures long service life. Cured foam can only be removed mechanically.
