Description
EP 402B
ALCHEMIX GELCOAT EP 402B is a two component, mineral filled, brushable, room temperature curing surface coat. Also available in White.
EP 4351
ALCHEMIX EP4351 is enriched with long glass fibre strands, and special fillers in a low-density epoxy resin specially formulated.   After mixing both components a very smooth consistency is achieved with good and easy to spread characteristics. Used as a back filling compound to support Rigid Gelcoats and flexible casting compounds.
EP 519
ALCHEMIX EP 519 with HARDENER H3, H7 or H8 is a cold-curing, two part, unfilled epoxy resin system. It is formulated for use in backfilling compositions using mineral or metallic fillers and for laminates requiring good flexural strength. It has excellent adhesion to metallic and insulating materials. It can also be used for applications such as coating of insulating tapes and locking of screws etc.
EP 521 / H521 / A521
ALCHEMIX EP 521 is a three part epoxy laminating system consisting of Resin, Hardener and Accelerator. The product has very low initial viscosity, low shrinkage and excellent reproduction of detail. Rate of cure may be adjusted by altering the quantity of Accelerator.
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.
R4
ALCHEMIX R4 is a liquid solution of polyvinyl alcohol (PVA) in ethyl alcohol. Release Agent R4 is intended for use as a mould release/parting agent for fabricating mouldings in polyester gelcoat and layup resins in GRP construction.
R5
ALCHEMIX R5 is a wax based aerosol release agent, which is free of silicone and chlorohydrocarbons. When applied in a thin coating, the carrier easily and quickly evaporates, leaving a thin film of wax on the surface. The wax can take temperatures up to 100°C without melting and boiling.
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 250
ALCHEMIX RTV 250 is a two component addition cure silicone rubber with the facility to alter the Shore 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 this 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.
