2、AY WSS-M21P45-A1 CORROSION PROTECTIVE COATING, BLACK WSS-M21P45-A2 1. SCOPE The materials defined by these specifications are corrosion protective coatings over steel. These coating systems provide corrosion protection and color and are intended for Spring Band Hoseclamps. These coatings are free of
3、 chromium, nickel, lead and cadmium. 2. APPLICATION These specifications were released originally for materials used for corrosion protective coatings over steel. They are intended for Constant Tension Spring Band Hoseclamps where a high level of corrosion protection is required. 2.1 SERVICE TEMPERA
4、TURE The maximum continuous service temperature resistance is 200 C. 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standa
5、rd Requirements For Production Materials (WSS-M99P1111-A). 3.2 LICENSEE APPLICATOR QUALITY REQUIREMENTS Applicators must follow coating manufacturer procedures and recommendations for chemical usage, equipment and processing. 3.3 MATERIAL PERFORMANCE 3.3.1 Raw Material Storage Stability The material
6、 must be capable of being stored at 23 +/- 2 C for 60 days without detrimental effect to the performance of the coated parts. 3.3.2 Cleaning Prior to coating, the parts shall be free of oil, scale, and similar foreign materials. The cleaning process shall have no detrimental effect on the substrate,
7、 including freedom from embrittlement.

Alternative cure temperatures may be used provided mecha
8、nical properties of the clamp are not affected. Parts must be sufficiently cured at the time of packing to withstand normal handling and shipping without marring. 3.3.4 Appearance A1 Uniform silver/silver gray A2 Uniform black The coating shall be uniform in color and free from discontinuities when
9、viewed without magnification. Where part grounding is required to apply the finish the grounding point shall be on the tang of the clamp and shall not impact clamp performance. 3.3.5 Storage Life Parts supplied shall still meet the specific requirements of this specification 6 months after receipt b
10、y Ford when stored at 5 to 28 C with no direct heat or sunlight. 3.4 ADHESION 3.4.1 The cured coating shall withstand normal handling, storage and installation without flaking or peeling or other loss of adhesion. 3.4.2 Parts heated to 120 C for 60 minutes shall not exhibit blistering, peeling, flak
11、ing or coating which can be removed by a filament type tape, such as 3M No. 898-2. The testing of coating quality by salt spray and/or determination of coating thickness will be performed on parts passing the adhesion test. 3.4.3 Hoseclamps may be used in Pre-Opened, Pre-Positioned (POPP) applicatio
12、ns; these are applications where the hoseclamp is glued to the hose to assist assembly. After a 16 hour soak at a relative humidity of 95% min. the adhesion of the coating shall be sufficient to withstand a load of 34Kg applied to the tangs in a horizontal or radial direction and shall meet the foll
13、owing requirements: 3.4.3.1 There shall be no separation of the coating and substrate. 3.4.3.2 There shall be no separation between coating layers. 3.5 RESISTANCE PROPERTIES PRECONDITIONING Prior to performing the restistance tests, the finished clamps shall undergo the following procedure to simula
14、te handling and transportation damage: a) Fill a cardboard box full of clamps to be tested. (No larger than 250X250X250) b) Secure the box thoroughly to prevent it from breaking open. c) Slowly slide the box off of a surface 0.75 meters onto the floor. d) Repeat step c 30 times, alternating between
