1.PRODUCT FEATURE OF GNS® PU GLUE FOAM GUN TYPE
●Powerful adhesion of polystyrene heat panels (XPS and EPS);
●Instant adhesion and wall plugging within two hours;
●Minimum 14 m² heat insulation panel adhesion for each can;
●Minimum expansion during drying period;
●After dried, no further expansion and shrinkage;
●A lighter material compared to plaster, alternative material, used in heat insulation systems;
●No more extra burden or weight to building;
●High yield up to 50 liters, depending on the humidity and temperature;
●Usable at low temperature like 0 °C;
●It does not contain any propellant gases which are harmful to the ozone layer.

7.FAQ
Q: What is the different of the pre-expansion and post expansion? Which one is better?
A: Pre-expansion is better. Post expansion will not only damage the doors and windows after curing, but also it will leads the cost of construction higher because more foam must be cut.
Q:What’s the impact for the PU foam with a big bubble or uneven cell?A: Small bubble or smooth cell is a common performance for good quality PU foam. Big bubble foam will cause thermal and sound insulation ability reduce and it may even be water leakage.
