Описание материалов:
BPS240 is a two-ply, partially impregnated epoxy prepreg system designed for the manufacture of Body-In-White (BIW) panels with excellent surface quality from vacuum-only processing at cure temperatures between 85°C and 150°C (185°F and 302°F).
The first ply utilises Cytec's ZPREG partial impregnation technology, consisting of a structural fabric coupled to a surface scrim and a high performance resin system. The second ply combines low-density syntactic core material and structural fabric to create significant panel rigidity in a rapid laminating format.
The system is designed to be ready for painting without abrading or reworking; in many instances, paint can be applied directly to a degreased panel. Excellent environmental performance can be expected from panels painted in Hi-Bake & Lo-Bake paint systems.
