High Temperature RED 375 rubber is the only grade of moulding rubber for the casting of white metals.
It sets moderately hard and offers good protection against chemicals and environmental contamination, shock and vibration. 375 moulding rubber is also used to encapsulate sensitive electrical and electronic assemblies.
Red Comes complete with hardener – add 0.25 to 1% of hardener to the rubber.
