WAX AND MOULD RELEASE

A Selection of The Composites Industry’s Finest Wax and Mould Release

Wax and Mould Release

Release agents are a vital part of the composites moulding process.  These form a barrier between a mould and the part being manufactured. The correct release system is essential to ensure the longevity of the mould, the quality of finish of the part, whilst also maximising the number of parts taken from the mould.

Tricel release agents are offered in the following three types: Mould Release Wax, PVA Release Agents and Chemical Release Agents which are available at each of our three UK locations and are available for immediate dispatch.

Mould Release Wax

Wax was the earliest release agent to be developed and can come in a paste or liquid and come in a range of natural and synthetic options. Mostly are applied by hand, but can also be sprayed on to the tool or mould. Waxes are applied directly to the mould allowed to air dry and are then buffed to a high gloss barrier. Wax can be easily removed with a degreaser and can be used with polyester, epoxy and vinylester resins.

PVA Release Agents

PVA is a water based release agent that can be used with epoxy and polyester resins. PVA can be hand wiped, sprayed brushed or rolled on to parts, and often comes in blue or red to confirm consistent application.

Chemical Release Agents

Chemical Release Agents offer a low build up and high gloss qualities and is considered a semi-permanent release agent. Works with polyester, epoxy and vinylester resin and all standard tool surface – it is often considered a go to product as it can be used in elevated temperature curing processes. Hand applied using a lint free cloth.

Waxes

Waxes, are still to date the most commonly used release agents for composites. It creates a durable wax surface that remains intact for multiple pulls. It is easy to apply and acts as a soft release paste wax that buffs to a high gloss finish.

Waxes can be used with polyester, epoxy and vinylester resins, and are usually applied by hand using a soft, lint free cloth.

Semi-permanent Systems

Semi-permanent release ages work at higher heats and are more chemical resistant than their temporary counterparts. It is particularly useful for moulds will be post painted or bonded as the release will not come off in parts.

Internal Release Agents

Internal release agents are dissolved in the resin mix and offer high release effect without impairing the chemical and physical characteristics of your mould.

PVA

PVA is often sprayed or wiped onto mould or pattern surfaces to offer a reliable release barrier. PVA can be used with polyester, epoxy and vinylester resins and gelcoats.

If PVA is applied over mould release wax, ensure the mould release wax contains no silicones as separation or `fish-eyes` will result if silicones are present. PVA release film can easily be removed from moulds and mouldings with water.

Release Film

Relelase film is most commonly used in wet laminating within a vacuum and offer excellent release using polyester, epoxy and vinylester resins. Providing the ideal restriction to resin flow between laminate and breather layer, allowing surplus resin to be drawn out of the laminate without excessive bleed-off of the resin.
