SCOPE This specification covers requirements for performance of polyolefinic and Polycarbonate/Acrylonitrile Butadiene Styrene (PC/ABS) body side mouldings,

3、 which are attached to the vehicle by high viscosity urethane adhesive and/or pressure sensitive tape. To improve the adhesion properties, the parts are to be treated by the SICOR process (Refer HN 2268) or primed with HN 1831. 2. GENERAL The body of the mouldings shall be made of a polyolefin or PC

4、/ABS suitable extrusion or injection moulding grade and shall conform to dimensions, section, colour and gloss as specified in individual part drawings. The moulding, shall not exhibit any blistering, blooming or plasticer migration after normal storage, or after any of the tests described in Sectio

5、n 5 of this specification. In the case of co-extruded mouldings, no separation or delamination shall occur between the sections. When mouldings are to have a bright decorative strip, the filament layer shall be embedded at its edge at least 0.5mm into the body of the mouldings to prevent the penetra

6、tion of water and the delamination of the strip. 3.
