RESION Vinylester resin is a very strong, heat-resistant and non-shrink resin that is ideal for mould making, osmosis treatment and heat-resistant products such as a hot tub. Vinylester resin can be used with all types of glass fibre, such as glass chopped strand mat and glass fabrics. In addition, the resin has good adhesion to various substrates such as old polyester, many plastics and metals. Vinylester is an excellent alternative if you cannot use epoxy. The product lends itself perfectly to an osmosis treatment of, for example, your boat or when you are going to make your own hot tub.

Benefits of vinylester resin

  • Faster curing and processing than epoxy.
  • Can be processed with glass chopped strand mat (and glass mat in turn is cheaper than glass fabric, which you have to use with epoxy).
  • Very high resistance to water and chemicals.
  • High resistance to osmosis.
  • Good adhesion to various substrates, like polyester, aluminum and steel.


The aforementioned advantages of vinylester resin make it suitable for a number of specific applications.

Osmosis treatment

Boat osmosis can be treated and prevented by using vinylester resin. Osmosis formation in the laminate of your boat can cause parts of the laminate to separate from each other (delamination). This causes it to lose tensile and flexural strength and thus reduces the strength of the hull. Vinylester resin is vapour-tight and therefore highly osmosis-resistant. This makes vinylester resin ideally suited to use for osmosis repairs or for osmosis prevention.

Heat resistant projects

Want to make your own hot tub? Due to its high heat resistance, during and after processing, vinylester resin is very suitable for making your own hot tub, swimming pool or jacuzzi. The high heat resistance of vinyl ester resin also makes it very suitable for other projects, such as mould making.


Colour: yellow/amber*
Heat resistance: up to 115 degrees celcius
Hardener: add 2% hardener for polyester
Size: 1 kg, 5 kg, 20 kg

Weight Hardener
1 kg 20 ml hardener
5 kg 100 ml hardener
20 kg 400 ml hardener

*Vinylester has a blue indicator. When hardener is added, vinylester turns green. After complete curing, vinylester, like polyster resin, has a yellow/amber appearance.
