10、ability. 2009 by Navistar, Inc. AUGUST 2009 Page 2 of 4 4.2 Paint Preparation The paint, covered in TMS-4505, is a single component system which is used for both the base and top coat as follows: 4.2.1 Base Coat Reduce paint with toluol, xylol, or SC-100 solvent, depending upon paint area temperatur
11、es. Reduction shall be two parts paint to one part solvent. Stir thoroughly before using. 4.2.2 Top Coat Do not reduce - use as received. Stir thoroughly before using. 4.3 Paint Equipment The following set-up kits and paint guns shall be used in applying the base and texture coats: 4.3.1 Base Coat K

Additional processing may be added if it does not affect the pe
13、rformance or appearance of the texture finish. 4.4.1 Spray base coat to a dry film thickness of 38 m (1.5 mil) to obtain complete hiding of the substrate. This will usually require two complete passes. Best results are obtained by painting each pass in opposite directions. Fluid pressure should be 1
14、38 kPa (20 psi) or enough to provide 0.65-0.71 liters (22-24 oz) of paint per minute delivery. Use 379-414 kPa (55-60 psi) air atomization pressure. 4.4.2 Let base coat flash dry three minutes or until dull. 4.4.3 Apply a uniform texture top coating over entire surface so that it matches the master
15、sample provided by Navistar. Fluid pressure should be 241-379 kPa (35-55 psi), with air atomization pressure set at 138-207 kPa (20-30 psi). Paint pressure must produce an unbalance of paint versus air to create the heavy texture particles. 4.4.4 Surfaces shall be air dry cured for 60 minutes or for
16、ce-dried at 52-66C (125-150F) for 20 minutes before handling. 4.5 Paint and Substrate Repair It is desirable to inspect the substrate for defects after the base coat has been applied and flash dried. If repairs are required, the parts shall be dried as indicated under Application 4.4.4, the area rep
17、aired and recoated with base coat, and the entire surface cleaned (tack rag). Then the entire part shall be processed with all steps shown under Application. If the texture (top) coat requires repairs after drying, the damaged area shall be sanded with 240 grit or finer paper, being careful not to e
18、xpose the base coat. After cleaning, recoat the repaired area with texture top coat, blending into the surrounding point. If the base coat is damaged or the laminate exposed, base coat must be reapplied. NUMBER: TMS-9000 TITLE: Texture Paint Processing Procedures REVISION: 0908 This document is rest

AUGUST 2009 Page 3 of 4 4.6 Handling Care must be used in handling air dried parts within first 72 hour
20、s after application, as total curing is not complete until after that duration. Do not store below 16C (60F) until after 72 hours to insure cure of finish. Parts which are air dried rather than force dried, as described under Paint Application, shall not be packaged for shipping for at least 72 hour
21、s after painting, although force-dried parts may be packaged after the specified 20 minute cure. 5.0 QUALITY Color and texture of parts supplied shall match the samples originally approved. Parts shall be clean and dry and free from objectionable odor. 6.0 SOURCE APPROVAL AND QUALITY CONTROL 6.1 Sup
22、plier Requirements All suppliers to Navistar are required to be registered to ISO 9001 Quality System Requirements. Navistar will also accept TS-16949 registration as long as the supplier can also fulfill all AIAG PPAP (Production Part Approval Process) documentation and approval requirements. Suppl
23、iers must maintain their certification with an accredited registrar and must furnish copies of registration certificates to their Navistar Corporate Buyer upon request. 6.2 Approval Parts supplied against contracts or purchase orders citing this specification shall be equivalent in all respects to t
24、hose samples, which were approved by the purchaser. No changes in formulation or processing practices are permitted without approval. In the event that changes occur in material properties, processing practices, or labeling, the supplier shall notify Materials Engineering at TDTC and Navistar Purcha
25、sing and Supplier Development of the proposed change(s). Test data indicating conformance to all requirements of this specification, test samples, and new/amended/updated Material Safety Data Sheet(s) (MSDS), in accordance with CFR Title 29, Section 1910, shall be submitted with the request for chan
26、ge. 6.3 Process Control The supplier shall either perform and report results of tests on specific lots of parts produced using ISO 9001 or TS-16949 guidelines, or provide statistical evidence of the lot having been produced in a state of statistical control and with a process capable of providing al
27、l required properties. The part supplier and the plant metallurgist and/or the quality control manager of the using NAVISTAR plant may determine testing and reporting requirements on specific products. 7.0 SHIPPING, PACKING AND IDENTIFICATION Shipping and identification shall be in accordance with N
