The key is in the chemical difference between platinum-cure (addition cure) and tin-cure (condensation cure) silicone mould making rubbers. But how does this affect performance?
Rubber materials, especially Polyurethanes, can vary in shades due to quite a few factors. This is very normal! But does colour have effect on performance of the cured material?
Not all casting resins are ideal for slush casting. Generally, this process is not good for for resins with working times longer than five minutes.
There are two reasons why your casting may have air bubbles in it. Find out how you can reduce or remove air bubbles with a few simple tips and one revolutionary product development.
When mould making or casting Silicones or Polyurethanes, cooler temperatures will slow down the curing process, while warmer temperatures will speed up it up.
