Clear Gun Foam can free rise up to 3x the original mixing volume, in lower temperature conditions the free rise ratio will decrease.
Weight to volume ratio: Example 500g Kit
500g Kit Part A is 375g - This equates roughly to 375ml in volume
500g Kit Part B is 125g - This equates roughly to 125ml in volume
500g kit is roughly 500ml in volume, so to mix a full 500ml at once at the correct working temperature of 25°C the foam will free rise to roughly 1.5 Litres, but if it is not used in the correct working conditions the free rise ratio will decrease.
