BOLL Polyester Resin

A polyester resin for use with glass fibre mat or cloth to repair larger holes and damaged areas in vehicle bodies, boats and trailers.

Also suitable for reinforcing and stiffening repaired components.

Provides very good adhesion to metal, plastics, glass and concrete.

Combines flexibility with a short curing time and temperature resistance up to 80°C.

Once cured, it has high mechanical strength and can be covered with polyester fillers.

COLOUR

• Yellowish

INFORMATION

Do not apply directly over reactive primers (wash primers), one-component acrylic products or nitrocellulose products.

Do not return unused resin mixed with hardener to the original container.

SURFACE PREPARATION

Steel and aluminium

Sand the surface, blow off the dust and degrease with BOLL Silicone Remover before applying the resin.

Existing paint coatings, two-component acrylic primers and epoxy primers

Sand with P150-P240, blow off the dust and degrease with BOLL Silicone Remover before applying the resin.

Polyester laminates

Sand with P80-P120, blow off the dust and degrease with BOLL Silicone Remover before applying the resin.

Plastics

Sand with P120, blow off the dust and degrease with BOLL Silicone Remover before applying the resin.

APPLICATION

1. Thoroughly clean and sand the surface to achieve a matt finish.

2. Remove the dust and degrease with BOLL Silicone Remover.

3. Cut the glass fibre mat so that it extends approximately 2 cm beyond the edges of the damaged area.

4. Mix the resin and hardener in the following ratio by volume:

• Resin: 100 parts
• Hardener: 2-3 parts

Alternatively, mix by weight:

• Resin: 100 g
• Hardener: 3 g

5. Mix thoroughly until a uniform colour is achieved. Do not exceed the recommended amount of hardener.

6. Pot life of the prepared mixture: 10-12 minutes at 20°C.

7. Use a brush to apply the mixed resin to the prepared area.

8. Position the pre-cut glass fibre mat and press it down.

9. Thoroughly saturate the mat with resin. Depending on the size of the repair, apply additional layers of mat, repeating the application and saturation steps.

10. Allow to cure for approximately 45 minutes at 20°C.

11. Sand the laminate with P80-P120 abrasive paper or level the surface with polyester filler.
