Liquid Self-expansion Fireproof Pu Foam For Door Window Frame Mounting
Junbond® PU Foam Spray polyurethane foam is a one-component, economical type and good performance Polyurethane foam. It is fitted with a plastic adapter head for use with a foam application gun or a straw. The foam will expand and cure by moisture in the air. It is used for a wide range of building applications. It is very good for filling and sealing with excellent mounting capacities, high thermal and acoustical insulation.Gun-straw dual use spray PU foam is our patented product which can be used by gun and straw.
Surface Preparation
lSurface should be cleaned of dust and mortar clods
lSurface should be sprayed with water using water sprayer
lProtect window profiles from the foam’s outgrow
Product Preparation
lThe can temperature should be between +10 ºC to +30ºC
lOptimal temperature of can is +20 ºC
l If can temperature is too low, the product should be put into warm water of +30 ºC for 15 minutes or left overnight in room temperature.
Product Application Instruction
lShake the can vigorously(20-30 seconds valve down) in order to mix the components
lScrew the can onto the adaptor
lThe working position is valve down
lVertical gaps should be filled from down to up
lDo not fill the whole gap-foam grows in volume
l If you fill window or door gaps, the gaps maximum gap size should be 3 cm. Foam should not be used in gaps larger than 5 cm.
lThe speed of application and the thickness of the bead should be controlled by the adequate pressure on the gun or adaptor trigger.
l If you stop the application for time longer than 5 mins, remember to shake the can before continuation of works.
Finishing Works
lThe excess of foam should be cut after the foam has cured. The foam should not be pushed back into the gap when it’s still uncured as it will cause structural defects and worsen insulation effect.
lAfter the foam has fully cured it should be protected from UV by mortar or paint.
l If you want to keep using the same can after longer time the gun and the adaptor and valve should be cleaned with the cleaner for polyurethane foams.
l Mechanical connectors recommended for doors mounting
