1. S UPPLIER C ONTAMINATION P REVENTION Guidelines and Awareness Training

2. Agenda Purpose Contamination and Craters Recommendations Summary S UPPLIER C ONTAMINATION P REVENTION

3. Purpose Contamination continues to be an issue at PPG Multiple occurrences related to raw materials, containers or transport Awareness training is part of PPG’s overall contamination prevention strategy S UPPLIER C ONTAMINATION P REVENTION

4. What do we mean by contamination? S UPPLIER C ONTAMINATION P REVENTION

5. What do we mean by DIRT? Any particulate or fibres found in our paint – excessive dirt can cause sanding issues at our customer site. S UPPLIER C ONTAMINATION P REVENTION

6. Craters are dish shape deformations in a paint surface. What is a CRATER? Some are shallow dimples, others are deep that penetrate to the substrate or layer below S UPPLIER C ONTAMINATION P REVENTION

7. Cost of Craters S UPPLIER C ONTAMINATION P REVENTION Disruption of an OEM assembly line Approximately $10,000 per minute!

8. Cost of Contamination Additional labor for sanding, repairs and rework Car bodies scrapped - $3000 each Paint system at OEM dumped & cleaned - $4000 + disposal costs Scrapped inventory at PPG Laboratory testing, site investigations and supplier claims S UPPLIER C ONTAMINATION P REVENTION

9. BIGGEST Cost of Contamination Loss of Customer Confidence Loss of business to PPG S UPPLIER C ONTAMINATION P REVENTION

10. Sampling attachment used on incoming solvent tank wagons Filter allows PPG to assess amount of particles and fibers Gels can be an indicator of crater causing contamination Failed testing will result in a rejected tank wagon Sampling attachment used on incoming solvent tank wagons Filter allows PPG to assess amount of particles and fibers Gels can be an indicator of crater causing contamination Failed testing will result in a rejected tank wagon Solvent Tank Wagons - Sampling and Testing S UPPLIER C ONTAMINATION P REVENTION
