Shape Rubber have announced a new material for creating moulds.
From their announcement:
Shape Rubber, Winchester have recently added a new grade of Siloset to there range of casting rubbers.
This grade CMLTB is a low temperature silicone compound and is recommended to be moulded/cured between 85 and 105degrees centigrade.
This buff coloured material has a lower hardness than the existing Red Siloset with a higher elongation, to help with those awkward undercuts and extend mould life.
Excellent for Master Mould manufacture.
