Bilko, NA Controlled document at www.MATS.com Copyright 2017, Ford Global Technologies, LLC Page 1 of 9 PAINT, POWDERED, THERMOSETTNG POLYESTER WSS-M70J5-C1 INTERIOR 1. SCOPE The material defined by this specifi
2、cation is for thermosetting polyester or polyester hybrid powder coatings as applied to unprimed metal substrates. The powder coating shall provide good initial appearance with adequate durability and corrosion properties. 2. APPLICATION This specification was released originally for powder coatings
3、 used on interior metal applications. All painted parts must meet WSS-M2P190-A/Latest. All paint applicators must meet the Interior Parts Painter Approval Process WSS-M2P195-A.These paint systems are typically used to decorate visible/non-visible metal surfaces (i.e. seat tracks, cargo shade compone
4、nts, brake pedals, etc.). This material is only for beltline or below applications. No IP green house or package tray areas. 3. REQUIREMENTS 3.1 APPROVED SOURCES This specification requires the use of approved sources. Only the sources identified on the Ford Approved Source List (ASL) can be used wh
5、en this specification is listed on the drawing, CAD file, or other documents. The list of approved sources is located within Ford at or available externally through a Ford Materials Engineer. 3.2 CONDITIONING AND TEST CONDITIONS All test values are based on material conditioned for not less than 24
6、 h prior to testing in a controlled environment of 23 +/- 2 C and 50 +/- 5% relative humidity. Testing of the material should occur in the conditioning environment or soon after removal. 3.3 COMPOSITION 3.3.1 Specific Composition When it is necessary to obtain specific data regarding powder coating
7、formulations, suppliers will furnish such data on request. 3.3.2 Vehicle Solids The vehicle solids shall be polyester resins modified with suitable cross linking, catalytic and flow control agents as necessary to meet the requirements of para 3.4 - 3.8. 3.3.3 Pigment The pigment portion shall contai
8、n the necessary corrosion inhibiting pigments and/or flattening agents to meet the requirements of para 3.4 - 3.8.
