Polyester resin: impregnation and protection solutions

Polyester resin is a widely used technical solution for applications in’Impregnation, casting and protection of industrial components. It is distinguished by its ease of implementation, its good cost-performance ratio and its ability to penetrate materials, making a relevant choice for many industrial applications.

Particularly suitable for impregnation and embedding operations, it allows for improvement of the durability, mechanical strength and protection of systems.

At ADDEV Materials, we support manufacturers in the bespoke selection and packaging of polyester resins, to optimise their performance and integration into production processes.

Polyester resin for industrial applications

In an industrial environment, polyester resin is used for:

  • component impregnation
  • The pour and the inclusion
  • surface coating
  • mechanical and environmental protection

It is particularly relevant for applications requiring a cost-effective and efficient solution.

Polyester resin is distinguished by:

  • better ease of impregnation than epoxy
  • a simpler implementation than some technical resins
  • A more optimised cost

It is favoured when simplicity and productivity are key criteria.

What is polyester resin

Polyester resin is a polymer material used for its properties of penetration, protection and rapid hardening. It is particularly suitable for impregnation and casting applications.

It is characterised by :

  • a low viscosity facilitating impregnation
  • a Quick bite
  • un low shrinkage during polymerisation
  • a Good mechanical and chemical resistance

It is ideal for applications requiring effective penetration and simple implementation
