Description
AC 8710
Alchemix AC 8710 is an aqueous dispersion of acrylic polymers primarily used as a binder for Gypsum based plasters in sculptures industry. It gives excellent strength to the plaster and reduces the fragility that is inherent to plasters. Alchemix AC 8710 is white in colour therefore does not affect the base colour of the plaster and can easily be pigmented. The product works perfect even at temperatures as low as near 0°C, however the cure time increases at lower temperatures.
CRS
ALCHEMIX CRS is an accelerator agent for ALCHEMIX RTV139, when added to the silicone mix it will halve the potlif and cure time.
PU 3501
ALCHEMIX PU 3501 is a flexible polyurethane moulding system with excellent tear strength and high elongation. ALCHEMIX PU 3501 is formulated for a broad field of applications where a high degree of flexibility and strength is required.
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 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 240
ALCHEMIX RTV 240 is a two component addition cure silicone rubber with the facility to alter the Shore A hardness by the use of different catalysts. Used for the moulding of complicated parts with precise dimensions. There is also a blue catalyst available for thei product.
RTV 272
ALCHEMIX RTV 272 is a two component addition cure silicone rubber with an extremely high tear strength and long mould life. Used for the moulding of complicated parts with precise dimensions.
