Film Release Agent
Release lacquer – Residue-free demolding with water-soluble PVA films
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 cleaningThe 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.
