Thixotropic mixtures based on semi-rigid polyester resins and different fillers. They are used in industry as “gluing” products and / or filling materials.
They are also used for the assembly of fiberglass parts.
They are made in different types:
- with fiber-glass: for the high adhesiveness and the high quality of the resins used, it is recommended for the assembly of pieces in fiberglass where great chemical resistance is required;
- without fiber-glass: recommended for filling and finishing edges or parts where fiberglass molding is more difficult.
- light (also called bonder). Thanks to the use of glass fiber microspheres (instead of the most common fibers) we are able to offer mastics with a light specific weight.
