Description

A polyester repair kit includes all the components required for quick and effective repairs of fiberglass-reinforced plastic (FRP) or similar substrates. The main component is pre-accelerated polyester resin, which cures with a hardener (MEKP) to create a strong, durable, and water-resistant composite.

Product description

  • Sea-Line® structural polyester resin is recommended for laminating, reinforcing the surface, and patching holes and damage – especially in situations where the most important is a fast repair time.
  • In conjunction with the glass mat, it is used for manual repairs of damage.To obtain a fully-fledged and adequately strong laminate, use a 2:1 weight ratio of resin to glass mat for polyester or a 1:1 weight ratio of resin to glass fabric.
  • To finish laminated surfaces we recommend using Sea-Line® fillers, Sea-Line® epoxy primers, Sea-Line® topcoats or a Sea-Line® gelcoat repair kit.

The set includes:

  • a polyester structural resin
  • hardener
  • fiber glass mat (0,25m2)
  • disposable gloves
  • a brush and a cup with a scale for easy dosing of ingredients
  • instructions for repair
