MacWax Release Spray

MacWax is a specially formulated wax release agent .Specifically designed for releasing polyurethane, polyester, epoxy and other plastics cast from various types of mould.  400ml Aerosol.

Special Properties:

• Low mould build up
• Easy Release
• Good sealing of porous surfaces

APPLICATIONS

MACWAX is suitable for use with many casting materials and a variety of mould types. Typical casting materials are polyurethane epoxy acrylic and polyester. Effective for moulding flexible semi-rigid and rigid polyurethane foams.

Use MACWAX  for high quality general purpose moulding at temperatures from ambient to 80°C. May be used where a silicone release agent is undesirable, such as when the moulded part needs to be painted or bonded.

Great for use as a sealant for wood, stone, cement and other porous surfaces prior to moulding. However, very porous substrates will probably require the application of a specialised sealant prior to application.

Usage Details :

Ready to use aerosol, shake well before use.

For best results hold the can 250 mm – 350mm away from the mould surface and try to keep the can moving during the spraying, otherwise patches of excess material will form. If possible, spray should be kept perpendicular to the area being sprayed.

Application :

A number of light coats is preferable to one heavy coat. Light coats allow the solvent to dry more rapidly and improves the surface finish. The application technique used will depend upon mould geometry. Deep Sections, undercuts and recesses can cause incomplete coverage from the release agent spray. This may lead to difficulty in releasing the moulded parts.

A thin sprayed coat should dry within 2 minutes at 20°C. Higher mould temperatures and a current of air over the mould will lead to shorter drying times. Casting onto release agent which has not fully dried may cause softening of the surface of the moulded part.
