Film Release Agent

PVA release lacquers (polyvinyl alcohol) form a visible, film-like separation layer that acts as a physical barrier between part and mold when laminating with epoxy or polyester resin. They can be applied to non-porous surfaces and can be removed with warm water after the resin has cured. PVA-based release lacquers are often used in combination with wax-based release agents and are especially suitable where a clean separation between laminate and mold is required.

Why is PVA release lacquer so popular in composite processing?

The use of PVA film release agents offers several practical benefits: they create a visible, film-like barrier, reliably prevent resin adhesion, and can be washed off with warm water after demolding – no sanding or harsh cleaners needed. Especially on steep or complex geometries and non-absorbent surfaces, the lacquer ensures a secure application process. PVA release agents are silicone-free – ideal when subsequent gluing, painting, or coating is required. They can be applied thinly and evenly using a brush or sponge.
 

Our selection of high-quality release lacquers for reliable demolding

Our water-soluble release lacquer based on PVA forms a thin, flexible protective film that ensures clean separation between laminate and mold tool. Drying time is about 5–10 minutes, depending on environmental conditions; the lacquer must be stirred well before and during use. For best results, we recommend pre-treatment with HP-G or HP-BM17 wax release agents. After curing, the dried film can be completely removed with warm water. Average consumption is approx. 60 ml/m², depending on surface texture and application quantity. PVA release lacquer is suitable for processing temperatures between +15 °C and +30 °C, and can be used up to a maximum of 100 °C.
 

What are the benefits of PVA release lacquer in composite applications?

> Residue-free demolding and easy cleaning
The PVA release film can be rinsed off easily with water – no sanding, no polishing. This saves time, protects the mold, and ensures a clean surface for further processing.

> Silicone-free application – ideal for follow-up processes
Our release lacquers are free from silicone – making them fully compatible with subsequent operations like bonding, painting, or laminating.

> Combinable and highly versatile
PVA release lacquer can be combined with wax release agents to protect delicate molds. It works on many materials – including GRP, CFRP, metal, and silicone – and can be applied by brush, sponge, or spray system.
 

Where is PVA release lacquer typically used?

PVA release lacquers are used in many areas where clean demolding and process safety are essential: in boatbuilding, mold making, model making, laminating, prototype development, or for negative mold production. In combination with epoxy, polyester, or PU systems, they offer a simple and reliable solution – suitable for both beginners and professionals. At HP-Textiles, you'll find the right PVA release lacquer for a wide range of molds, resin systems, and processing methods.
