One-component RESION polyurethane resin as an adhesive layer for polyester resins on wood, concrete, masonry, old polyester and epoxy layers, metals etc. Also suitable for model making, as a base layer for further processing or as a finishing layer. By applying this adhesion primer, you get a very good adhesion with the polyester laminating resin in combination with the fibreglass mat you want to apply later.

The G4 adhesion primer consists of one component, so you don't need to mix the polyurethane resin with a hardener and you can apply the resin directly to the substrate with a flat brush or a fleece roller. You can dilute the bonding resin with PU thinner if desired. Depending on temperature and humidity, you can then continue processing polyester after just 30 minutes.

By evaporating, the bonding resin will dry and, when dry, you can continue processing the polyester resin.
