2、INT, AIR OR FORCED DRYING, FUEL TANKS WSS-M1J216-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is an air drying or force drying paint. It is essentially for providing fuel tanks with improved cosmetic appearance, and enhancing the resistance performance of the s

3、ubstrate material. 2. APPLICATION The material is generally used for coating lead plated steel (Terne Plate) fuel tank surfaces. The material must be suitable for pneumatic, airless and electrostatic application. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers a

4、nd part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.4 COMPOSITION 3.4.1 Vehicle The resin shall be based on a suitable synthetic system to obtain the desired application and resistance properties. 3.4.2 Pigment The pigment shall be balanc

5、ed and blended to give the desired color, normally black, unless specified on the component drawing. 3.4.3 Solvent Solvents should be balanced in order to provide suitable storage and application viscositys, while at the same time avoiding flocculation and maintaining correct solvent emission levels

6、. 3.4.4 Specific Composition When it is necessary to obtain specific data regarding material formulation, it is understood that the supplier will furnish such data on request. It may be necessary to supply such information in order to clarify the toxicological status of the material with respect to

7、National or Local Protection Agency constrictions.
