Bonding paste flex with fibres

Adhesive bonding paste with high elasticity based on unsaturated polyester resins and reinforced with fibres.
Used in the composite sector for its excellent adhesion for the bonding of laminates and inserts of various types.


Fiberglass polyester and vinylester, wood, various types of foam.


Apply on well sanded and cleaned surfaces;
Make sure the substrate is free of dust, fibres, dirt and surface condensation.
Carefully mix the mastic with 1,0 – 2,0% of liquid hardener (methylethyl ketone peroxide), bearing in mind that the amount of hardener required depends on the temperature of use and the processing times required.
The recommended temperature range is between 16 and 28°C.
It must be applied manually with a spatula after careful mixing the hardener or by machine.
For quantities over 5 kg, mixing with a stirrer is recommended, while for 200 l drums, the use of a pressing plate extruder/mixer guarantees the best mixing efficiency.
In its original packaging, the product can be used for 6 months if stored indoor away from direct sunlight, at temperatures not exceeding 20°C. Some drift may occur in gel time.
