DESCRIPTION

Fiberglass polyester putty designed for bodywork, railway equipment, machinery, vessel repairing, for filling dents, cracks, perforations or chips in steel, cast iron, aluminum, electro-galvanized galvanized steel or polyester fiber laminates of GRP glass. Also usable in the construction of models and prototypes where an easily mouldable material is required.

It stands out for its creamy consistency and easy application, its low density that allows a good filling power in layers of 2-4 mm., good resistance and sandability with finer grains than conventional putties. It increases the mechanical resistance of the repaired item.

HARDENERS

The use of an electronic scale is recommended. Mix homogeneously to avoid the formation of air bubbles.

Note: Adding more hardener is not recommended in order to prevent bleedings in the paint.

Application: By spatula.
The hardener mixture can be carried out on the same spatula, homogenizing it well before applying.

When a deep filling is required, apply several layers, letting them dry at each time during the process. Sanding at each stage is recommended in order to obtain better adhesion between the coats.

SURFACE PREPARATION

The surface to be repaired must be free of rust and grease, for which we recommend previous sanding (P80-P120). On electro-zinc plating better use StarBrite.

Do not use this putty on wash-primer or phosphochromatic primers. If the original paint is thermoplastic acrylic, bare metal must be reached.

For greater substrate protection, especially in steel, use first a primer from BESA’s product line such as F-286/2.
Recoatable with any Acrylic or Epoxy finish system once sealed, preferably with a 2K filler from the BESA product line.
