Formulated starting from highly selected raw materials, they are used in the PRFV sector and are used in applications where, in addition to absolute adhesion between the fiberglass parts, the structural parts in general and the foams, low shrinkage is also required.
The basic binder is made up of styrene resins of different nature, selected according to the use that the finished product must satisfy: water resistance, chemical resistance, better adhesion to the reinforcing fibres, wettability of the fillers present in the system, adhesion to the support on which they are used.
They are supplied already accelerated, to be catalyzed with the types of peroxide normally in use, with variable gel time to meet the customer’s application needs or follow the seasonal trend, winter or summer. In many of them there is color changer, an additive that allows you to visually check the presence of peroxide and its perfect homogenization in the Bonding paste mastic.
