scope:

Dexcribes surfaces preparation for plastics adherends to be used prior to adhesive bonding. Plastic materials are often bonded to other types of surfaces, particularly metal. Consequently, reference is made to ISO 4588 and EN 923 standard. Plastic surface often require preparation to remove contamination and additionally to improve the wetting characteristics of those possessing a low energy surface. Preparative techniques such as abrasion improve performance by increasing mechanical interlocking. Certain adhesives possess the ability to dissolve light oils and some polymeric materials. Consequently, some surfaces may not require preparation prior to bonding. Reference is made to this in the table of Clause 8. Consult the suppliers involved for specific advice.
