Description

2-component flexible polyester putty designed for car repairs. Especially recommended for repairing plastic body parts exposed to vibrations. It shows very good adhesion to most types of plastics. Thanks to its exceptional flexibility, protects the repaired surface against cracking.

Advantages

Very good adhesion to plastic.
Exceptionally high flexibility.
Good sanding properties.
Very smooth surface after sanding.

Substrates

The product has very good adhesion to all outer plastic panels (PP, EPDM, ABS, PC, PPO, PA, RTPU, PBTP, PVC, PUR, PUR soft foam, UP-GF).
Before applying, the surface should be well cleaned with an abrasive needled cloth and degreased with detergent and water (do not use benzene based removers as they can dissolve the surface). Wash again using water and detergent, rinse with pure water and dry with air. It is recommended to heat the element to 50°C before starting application. This will help remove any silicone from the plastic surface.

Caution: Do not apply the putty directly on the reactive primers, 1K acrylic and nitrocellulose products.

Pot life is 3÷5 minutes at 20°C.

Hardening time
25÷35 minutes at 20°C.
Temperature below 20°C significantly increases the hardening time.

Sanding
Coarse sanding (dry): P80÷P120.
Finish sanding (dry): P120÷P320.

Further work
Polyester putties can be over coated with:
- 2K acrylic primers.
- 2K epoxy primers.
It is recommended to ground plastic panels with 1K Plastic Primer before applying acrylic primer.

General notes
- Excessive amount of hardener will cause problems with bleaching of the topcoat!
- When working with 2K products, it is recommended to use personal protection equipment. Protect the eyes and air ways.
- Clean the guns and equipment immediately after use.
- The rooms should be well ventilated.
Caution: To maintain safety, always follow the instructions given in the MSDS for the products.
