Black Gun Foam has been formulated for use primarily for moulding and casting applications requiring a good skin to the finished product. This product is widely used within the film prop industry as it enable safe and durable production of props.
Cream Time (100g 20°C) - 15 - 25 seconds
Rise Time (100g 20°C) - 2 minutes
Demould Time (components @ 20°C , Mould @ 35°C) - 20 minutes
Full Cure (100g 20°C) - 12 hours
Black Gun Foam can free rise up to 3x the original mixing volume, the example listed below was a mix ratio of 3:1 totalling 50g (37.5g Part A + 12.5g Part B) in a working environment of 25C
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 25C 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.
