Description
8806
ALCHEMIX 8806 is a non reactive silicone oil used for viscosity and hardness adjustment of RTV silicone rubbers
CRS
ALCHEMIX CRS is an accelerator agent for ALCHEMIX RTV139, when added to the silicone mix it will halve the potlif and cure time.
RTV 104
ALCHEMIX RTV 104 is a thixotropic agent to be used with RTV 134, RTV 137 and RTV 139. When added to the silicone mixture it will thicken the material depending on how much agent is sdded.
RTV 130
ALCHEMIX RTV130 is a white two component, low strength rubber.
RTV 132
ALCHEMIX RTV 132 is a two-component condensation cure, low viscosity silicone rubber. Suitable for mould making, producing replicas of polyester, epoxy resins, urethane foam and wax etc. It can precisely reproduce the shape of the original model. ALCHEMIX RTV 132 has exceptionally high tear strength and good elongation. There are a number of catalysts available for this product.
RTV 134
ALCHEMIX RTV 134 is a two-component condensation cure, low viscosity silicone rubber. Suitable for mould making, producing replicas of polyester, epoxy resins, urethane foam and wax etc. It can precisely reproduce the shape of the original model. ALCHEMIX RTV 134 has exceptionally high tear strength and good elongation. The cure time can be varied by catalyst addition between 2 and 5%.
RTV 136
ALCHEMIX RTV 136 is a two-component condensation cure, low viscosity silicone rubber. Suitable for mould making, producing replicas of polyester, epoxy resins, urethane foam and wax etc. It can precisely reproduce the shape of the original model. ALCHEMIX RTV 136 has exceptionally high tear strength and good elongation. There are a number of catalysts available for this product. .
RTV 137
ALCHEMIX RTV 137 is a two-component condensation cure, low viscosity silicone rubber. Suitable for mould making, producing replicas of polyester, epoxy resins, urethane foam and wax etc. It can precisely reproduce the shape of the original model. ALCHEMIX RTV 137 has exceptionally high tear strength and good elongation. The cure rate and potlife can be altered by varying the catalyst addition between 2-5%.
RTV 139
ALCHEMIX RTV 139 is a two-component condensation cure, low viscosity silicone rubber. Suitable for mould making, producing replicas of polyester, epoxy resins, urethane foam and wax etc. It can precisely reproduce the shape of the original model. ALCHEMIX RTV 139 has exceptionally high tear strength and good elongation.  
RTV 201
ALCHEMIX RTV 201 is a thixotropic agent to be used with ALCHEMIX RTV 240. When added to the silicone mixture it will thicken the material depending on how much agent is added.
