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.

Wax Release Agents

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.

Our release waxes are chemical agents that prevents your part form attaching permanently to the surface of your mould. It is particularly useful in casting and is often considered the oldest form of mould release. Wax is easy to apply by hand, and can be used on new and existing moulds (make sure you give it a good clean first!).

Two of our most popular wax products; Meguiars mirror glaze and Honey Wax.

Meguiars Mirror Glaze creates a barrier film, with ultra-high gloss finished parts. When applied correctly it offers multiple releases without the need to re-apply. Mirror Glaze is recognised as the industry’s ‘standard’ for paste mould release wax. It can withstand exothermic temperatures up to 121˚C.

Honey wax is a high gloss past wax, compounded with the purest grade carnauba wax. It is more durable and resistant to abrasion. Honey wax creates a durable wax surface that is suitable for multiple pulls.

PVA Release Agents

PVA release, unlike its wax counterparts can be sprayed or wiped on to a range of mould surfaced and is a reliable release barrier for polyester, vinyl ester and epoxy composites. PVA does leave a texture on a finished part which will need to be polished out, making it used when release issues are more likely.

Our PVA release come in a blue colour so that when applying to your mould, you can see where has been covered and where still requires attention. Only one coat should be applied, as additional coats will result in an uneven surface.

Moulds must be thoroughly cleaned before re-applying, expensive cleaning products are not always necessary, as often water and lint-free cloth will be enough to clean a mould.

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.

We offer an expansive range of release agents that can enhance productivity, improve part and surface quality. We offer water based, solvent based, silicone and silicone free release products that offer improved operational efficiencies and product quality.

Our semi-permanent release agents offer many mould releases between applications and offer efficient release ease. Small amounts can be applied resulting in a cleaner working environment, less storage space required and better efficiency due to applying the release system less frequently.

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.
