Vinylester, is a resin produced by the esterification of an epoxy resin with an unsaturated monocarboxylic acid. The reaction product is then dissolved in a reactive solvent, such as styrene, to approximately 35–45 percent content by weight.

They are used in marine , wind turbine production and automotive sectors. They are also used in advanced level production of structural panels in the aviation industry.

They are pros and cons Vs Polyester resins and we leave to the client lab to create their own formula we will be happy to assist.


Gelcoats are indispensable to protect the material against external impacts but they provide also a perfect appearance

Our partner has undertaken numerous research in the fields of scratch resistance, chemical resistance, gloss and colour stability.
Gelcoats are offered either transparent or with RAL and matching Pantone codes .
And you can choose general purpose gelcoats or high performance gelcoats in 4 categories as follows :

  • Orthophthalic - General usage with cost saving as priority
  • Glossy topcoat – replacing former mat surface topcoats with a shiny surface up to 90 gloss.
  • Isophthalic – Chemical resistance and physical resistance as priority
  • NPG/ Isophthalic – Adding Neopentyl Glycol is it used top of the range for harsh climatic condition with an higher chemical resistance

Phthanolitrile Resin

Our partner is producing  a one-component phthalonitrile resin with operating temperature up to 450°C.
The processability of this resin is similar to that of epoxy resins: impregnation is done at a temperature of 160°C, the preliminary curing at 180°C . It is designed for composite structures manufacturing by vacuum infusion and RTM.

  • Operating temperature up to 450°C;
  • Impregnation temperature is 160°C;
  • Pre-curing temperature is 180°C and post-curing temperature is 375°C;
  • Low moisture absorption;
  • Low viscosity;
  • Softening temperature is 80°C.

Medium Viscosity Resin

Presenting an unmodified, medium viscosity, liquid epoxy resin based on

When it is used with an appropriate epoxy curing agent it provides an
excellent combination of mechanical,thermal, chemical and physical properties.

High Performance Epoxy Resin

We are presenting an Ultra High Temperature-resistant Low Viscous epoxy resin.
Which is Suitable for production of a variety of high-performance composite with the following performance.
Excellent wetting performance for glass and carbon fibers.
Low viscous and easy to use, especially suitable for vacuum infusion process.
May be cured at room temperature then proceed the post-curing, which broadens the usage of the product.
