7、f first supply and changes as per Volkswagen standard VW 01155.Avoidance of hazardous substances as per VW 91101.In case pretreatment is necessary to activate the substrate, the related method must be specified(e.g. flame exposure, plasma treatment).The coating/paintwork, as well as any refinishing
8、paint, must adhere firmly to the substrate or to theoriginal paintwork, as the case may be.All areas of parts which are not subject to the requirements stated in this TL standard must beidentified as such in the drawing.Master paint and hardener from the same manufacturer must be used for two-compon
9、ent compositions. Any deviations must be coordinated with the Volkswagen Group department granting the release.The supplier must provide the following information for all parts to be tested:1. Specification of the base material (manufacturer designation and VDA (German Association ofthe Automotive I
10、ndustry) designation)2. Color3. Paint structure (precise paint specifications, paint supplier), e.g.:Primer coat: Two-component primer 01-79008, by XXX, 20 mBase coat: 831646, by XXX, 20 mClear coat: Two-component clear coat GP72-0113, by XXX, 22 m4.

11、. Painting dateAppearance and haptic characteristicsThe parts must exhibit a uniform appearance on their entire surface; they must conform to thedrawing requirements and to the released sample with respect to gloss and color.Pores, coarse cracks, and other flaws that adversely affect the specified a
12、ppearance are not permissible.Color and gloss level must be documented in the first-sample test report or development sampletest report as per VW 50195.Open-air weatheringAll painted components in the Volkswagen Group are subjected to open-air weathering as perVW 50185.The supplier is obligated to r

Both parties confirm the first-sample test report, meaning that both are re
14、sponsible for fulfilling the specifiedrequirements.Responsibilities are broken down as follows: The paint manufacturer provides information on whether the TL requirements are being met. Inaddition, it provides its processing guidelines and provides support for the paint method used. The paint shop p
15、rovides information about the substrate (type of plastic material and commercial name), checks the requirements as early as possible (this also applies to pre-productionparts: at least for adhesion), confirms compliance with the paint manufacturers processingguidelines, and requests assistance regar
