Light Polyester Bonding Paste

Lightweight adhesive bonding paste based on unsaturated polyester resins, microspheres and light reinforcing fillers. Specifically formulated for the composite sector for bonding core materials and inserts in Balsa, PVC, PET, PIR and polyurethane foam.
It is easy to apply, spread with spatula, easily deareates and stick to the surface thanks to the excellent tixotrophy. Under pressure or vacuum it flows easily saturating every crack and cavity of the foam thus ensuring high mechanical, thermal and chemical properties to the sandwich laminate. The low specific weight of its formulation is combined with limited shrinkage during hardening and excellent adhesion performance even on high density foams. The product contains a “color-changing” pigment (Viracolor) in order to verify the homogeneous dispersion of the peroxide.
