SCOPE These specifications define the performance requirements of various

4、types of engine paint systems, when applied over both Rigid (Metallic) and Non-Rigid (Plastic) Substrates. 2. APPLICATION These specifications were released originally to define paint performance for engine blocks, oil pans, engine accessories, brackets, etc. as well as sheet metal and plastic parts

5、 within the engine compartment. WSS-M2P185-A1: Paint systems per this specification provide excellent adhesion, chemical and heat resistance as well as superior corrosion protection for and stone chip resistance. They are designed for highly visible applications and can also be used in engine interi

6、ors, e.g. the oil pan. Appropriate paint systems are cathodic electrocoat primers with added application of powder coat where increased stone chip resistance properties are required. WSS-M2P185-A2: Paint systems according to this specification provide good adhesion; chemical and heat resistance as w

7、ell as good corrosion protection and stone chip resistance. They are designed for highly visible applications, e.g. engine blocks. Appropriate paint systems are electrocoat primer or high film build powdercoat. WSS-M2P185-A3: Paint systems according to this specification provide moderate chemical an

8、d heat resistance and moderate corrosion protection. Appropriate paint systems are low/medium film build powdercoat or engine enamel.
