Before use, 5% of Hardener HT (50g) is added to PRIMER SC. Thus prepared primer is usable for 4 hours. Metal surfaces on which PRIMER SC is applied are pre-prepared by sanding or sandblasting. If rust is present on the metal surface, use a rust remover. Before applying PRIMER SC, metal surfaces are cleaned and degreased with INTERSOL NF cleanser. On such a cleaned metal surface PRIMER SC is applied with a brush. The drying time of the primer is 30-60 minutes. The adhesive is applied in two coats over the dried primer. The drying time is 30 minutes for the first coat and 10 minutes for the second coat. At the same time, the adhesive is also applied to the rubber surface, which is pre-prepared by sanding and cleaned with INTERSOL NF. Two coats are also applied on rubber, and drying time is the same as on the metal. Joining rubber and metal is performed by applying pressure necessary for the surfaces to touch. For joints exposed to temperatures below 100°C, PRIMER SC can be used without HARDENER HT.
