Description

Since the 2024 closure of Jacobson Chemicals Ltd in the UK, the J-Wax brand is no longer available. We were able to source this product directly from the manufacturer. Enjoy all the benefits and properties of J-Wax in the new MACWAX packaging.

MACWAX spray mould release agent is a blend of waxes dispersed in rapid drying solvents and packed in aerosol form. This product does not contain CFCs, 111-trichloroethane or any other kind of halogenated solvent. MACWAX is suitable for use with many casting materials and a variety of mould types.

MACWAX is classed as a general purpose release agent, however it far surpasses most release systems on the market. Designed for use at moderate temperatures where a silicone release is not desired. It provides a matte finish when applied and can also be polished when applied to rigid surfaces. MACWAX is perfect to PU-PU moulding, but may also be used to release silicone and epoxy systems. Special properties include low mould build-up of residues, easy release and great coverage.

Key Features:
– 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. MACWAX is also used extensively for moulding flexible semi-rigid and rigid polyurethane foams.

MACWAX has been formulated for high quality general purpose moulding at temperatures from ambient to 80°C.

MACWAX may be used where a silicone release agent is undesirable such as when the moulded part needs to be painted or bonded.

MACWAX may also be used as a sealant for wood stone cement and other porous surfaces prior to moulding. Very porous substrates may require the application of a specialised sealant prior to application of MACWAX

Usage Details:
The material is in a ready to use aerosol. It should be shaken well before use.

The aerosol can should be held 250 mm – 350mm away from the mould surface. The can should be kept moving during the spraying otherwise patches of excess material will form. If possible the spray should be kept perpendicular to the area being sprayed.

The application of 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 often cause incomplete coverage by parts of the mould surface 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.
