palm mould silica gel

Overview:
Palm mould silica gel is a special room temperature vulcanization gel for mould making because of it's low contractibility,good emulation,anti-high&low temperature,anti-chemical, easy mould release,good compatibilty,conveniently machine-shaping,long time for using and so on.
Application:
Reproduction of the cultural relics,investment casting.high frequency embossing,jewelry,artware,furniture(copied europeanism bed shield,picture frame,copied rosewood carve and so on),technical ceramics,human organ copy, architectural ornament,sculpture,technical ornament copy.It also can be used in making products of art craft polyamine resin,PU,epoxy resin,paraffins,gypsum,alloy of low melting point and so on.

How to use:
1.Mix A and B as property proportion,mixing with 3~15% silicone oil depends on the conditions,which rejects foam and increase levelling property.
2. Fully stirring the silicone rubber, then put them in vacuum and pump 3-5 minutes below 0.095Mpa,make moulds after bubbled.
3.Adjust the amount of hardener according to the excel list above.Add too much hardener and operate too short time will weaken the properties of products. 
4.Do spray paint the original model to avoid demoulding.
