1 TEGOMER AntiScratch 100 Make your plastic tough enough Scratch resistance for PP/talc

2 Automotive Applications of PP/talc with High Importance of Scratch Resistance Dashboards Interior door panels Page 2

3 All properties are effected by antiscratch additives Customer s Expectations for Interior Surfaces & Materials are Very High To meet customer s expectations the following parameters for materials need to be fulfilled: Design (color, structure of surface, leather like appearance) Haptic, Touch (soft, hard, sticky, smooth) Durability (is it sensitive to damage by UV light or heat?) Odor free (new car smell vs. new car malodor) No fogging ( smeary window ) The quality impression of the interior determines the quality impression of the total car! Page 3

4 Door Panels are a Typical Application for Antiscratch Additives Antiscratch properties are needed because Car customers & designers like grained surfaces ( leather style ) These surfaces are very sensitive to scratch, e.g. damages of door panels Industry standards for grained surfaces K 09: strongly grained (standard of VW) K 31: smoothly grained (standard of GM) K 09 Grained surface of VW moulded in our lab Page 4

5 A Durable Scratch Resistance Ensures a High Perceived Quality An unscratched interior after extensive use Creates a high value brand recognition especially with rental cars or taxis Influences positively the decision when a new cars is bought towards the current brand Allows a higher selling price when a used car is sold Makes it more likely that the customer will buy a new car from the same brand/oem Page 5
