Tiranti RTV640 Addition Cure Silicone Rubber Kit
RTV640 Addition cure silicone is the new replacement of Addition cure 33, this translucent low shrinkage silicone has a high chemical resistance and has a shore A hardness of 40.
As with all addition/Platinum cure silicones there are some materials with which it is not compatible, and which will inhibit the cure. The cure can be inhibited by the presence of nitrogen, sulphur, phosphorus, arsenic, PVC stabilisers, epoxy resin, this includes contact with materials that contain these substances such as latex, plasticine, some ceramic clays, sulphur vulcanised rubbers, condensation cure silicones, onion and garlic (due to the sulphur content). If you are uncertain about the compatibility of your modelling material, please test a small sample before completing the project.
Shore A Hardness 40
Full Cure Time 11-13 hours
Pot life 90 mins
Mixing ratio 1:1
This silicone is suitable for use with our thixotropic paste Addition cure thixo alternatively our new thixo also works well. RTV thixo paste
Curing is temperature dependent; a warm environment will accelerate the cure; cooler temperatures will have the opposite effect.
