Description
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.
R6
ALCHEMIX R6 is a silicone based aerosol release agent for epoxy, polyurethane, polyester and many other materials.
R7
ALCHEMIX R7 is a wax based liquid release agent, which is free of chlorohydrocarbons and silicone. 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 90°C without melting and boiling.
R8
ALCHEMIX R8 is a PTFE release agent for use on metals, wood, leather, rubber and ceramics. Release Agent R8 is especially useful as a running in lubricant for packing and for applying to gaskets to aid easy removal.
