Clear 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.
Product Characteristics
| Polycraft Clear PU Gun Foam | Unit |
| Mix Ratio By Weight | 3A : 1B |
| Cream Time (100g @ 20°C) | 15 - 25 Seconds |
| Rise Time (100g @ 20°C) | 2 - 3 Minutes |
Demould Time
(Components @ 20°C & Mould @ 35°C) | 20 Minutes |
| Full Cure (100g @ 20°C) | 12 Hours |
| Free Rise @ 25°C | Up To 3x Volume |
| Free Rise Density g/mL | 0.15 - 0.25 |
| Cure Colour | Off White / Cream |
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.
