Business Guide About Epoxy Resin Release Agent

release agent for epoxy resin

A mould release agent is a chemical that hinders the adhesion of specific materials to one another. If you don’t employ a releasing agent, these components will stick together, which will make cleaning and achieving a precise casting more difficult.

Do you frequently utilise epoxy resin and moulds? You’ll see why you need an epoxy release agent after that. If you don’t want your epoxy resin to stay to your mould, always apply an epoxy release agent. The resin mould release agent is used not just on small castings, but also on larger projects. For example, epoxy resin can be embedded in wood or other materials.

epoxy resin material

With science and technology development, epoxy composite material on the technology progress, applied in all walks of life more and more widely, because the epoxy composites has light weight, high strength, easy to processing molding, good elasticity, good resistance to chemical corrosion and weather resistance, so the wood and metal alloy gradually replaced by the epoxy composite materials.

What is Epoxy Resin Release Agent?

Epoxy resin release agents work by preventing epoxy resins from clinging to moulds. They’re needed to remove resin casts from moulds. These are available in a variety of spray forms, including aerosol and non-aerosol. Epoxy releasing agents are typically made up of polyvinyl alcohol and other similar compounds. These are used to cover moulds and provide a film that allows castings to be easily removed.

Normally, an epoxy release agent is applied to a mould before it is cast. The casting will stick to the mould if this is not done, and it will be damaged. It’s also worth noting that porous materials like wood or plaster should be sealed before applying epoxy resin. These porous materials will attach to the resin and will be impossible to remove without causing damage.

It’s also critical that any moulds you use are completely dry and clean. Debris that gets into the resin might destroy your product as well as the mould. It’s a good idea to inspect and clean any moulds you plan to use before starting a project.

Why we need release agent for epoxy resin?

In the process of epoxy products production, in order to prevent the product stick to mold, before hand paste molding the mold is coated with a layer of separation substance —- release agent.

Types of Epoxy Release Agent

There are many types of release agent, divided into film type, mixed type and oil wax type.

  1. Film release agent: often used cellophane, polyester (dacron) film.
  2. Mixed solution release agent: commonly used is polyvinyl alcohol, polyacrylamide solution, silicone rubber solution, polystyrene solution.
  3. Ointment, wax type release agent: generally with low melting point paraffin adding some solvents and other materials modulated.

Application of Epoxy Release Agent

Epoxy release agent can be used in a variety of molding processes, such as high temperature molding, hand paste molding, autoclave molding, winding molding, pultrusion molding, laminating molding, vacuum filling molding.

Sakurai epoxy release agent is a special release agent for new composite materials, suitable for all kinds of epoxy composite firing rod system, such as carbon fiber badminton rackets, wind blades, fishing rods, golf clubs, bicycle frame, arrow shaft, tennis rackets and other carbon fiber pipe release.

How to use epoxy release agent

Firstly, the mold surface must be clean and remove any dirts before spray epoxy resin release agent. If any residue is left on mold surface, the release agent can’t adhere to the mold, because release agent will straightly flow over the surface without film forming, which cause sticking mold problems after epoxy resin cured.

After the mold prepared, spray or brush mold release agent to the mold surface, until fully cover thesmall cavity with a thin layer. Recommend to spray on the mold from 20-30cm distance. Solvent based release agent drying takes 3 minutes, but water based release agent is drying much slower which depends on the mold temperature and ambient temperature.

As for new molds and the cleaned mold, we suggest to apply three layers of mold release agent, ensure to seal all small cavities before casting resin. After spraying each layer, allow time to dry before applying another layer.

What we need to know when choose epoxy release agent

We should consider the following factors when choosing epoxy release agent:

  1. Mold material
  2. Type of molding process
  3. Type of resin
  4. Curing temperature
  5. Product structure
  6. Production cycle
  7. Economic benefits
  8. The requirements of the product surface effect after molding
  9. Post-processing demand
