- heat-adhesive protection patches (FOPS), protecting from infiltration of moisture through openings for foaming – 2 pieces
MTF1joints are wrapped in white LDPE foil and should be stored and transported in upright position to avoid ovalization. Maximal temperature during storage and transport shall not exceed 70°C.
During assembly of the joints components of polyurethane foam (PUR) are to be used. When ordering please provide information if the joints are to be delivered together with PUR foam.
