TEGOMER AntiScratch 100 - Plastic Additives

1 TEGOMER AntiScratch 100 Make your Plastic tough enough Scratch resistance for PP/talc Page | 2 Automotive Applications of PP/talc with High Importance of Scratch Resistance Dashboards Interior door panels Page | 3 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! All properties are effected by AntiScratch Additives Page | 4 Door Panels are a Typical Application for AntiScratch Additives K 09 Grained surface of VW moulded in our lab AntiScratch properties are needed because Car customers & designers like grained surfaces ( leather style ) These surfaces are very sensitive to scratch, damages of door panels Industry standards for grained surfaces K 09: strongly grained (standard of VW) K 31.

2 Smoothly grained (standard of GM) Page | 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 | 6 Perfect Long Lasting Scratch Resistance for Less than 10 EUR Calculation Amount of PP/talc used in a standard mid size car: 55 kg Thereof PP/talc parts with need for AntiScratch properties: 15 kg Amount of TEGOMER AntiScratch 100 needed (at 2%): kg = < 10 EUR Families would buy it!

As a reliable partner we offer all Standard Tests In-house Page | 10 A chemically bond Permanent Slip Enhancer Polymer matrix (dashboard) Anchorage groups Siloxane backbone TEGOMER AntiScratch 100 The anchorage groups of TEGOMER AntiScratch 100 ensure in contrast to standard Additives a durable & permanent set No migration, no fogging, no property change over time, no impact on surface haptics Page | 11 Exclusively TEGOMER AntiScratch 100 Generates a Long Lasting Effect 0,0 2,0 4,0 6,0 8,0 10,0 12,0 Compound: PP with 20% talc Test method: Erichsen 10 N Graining: K31 L 24 h L 1 W 80 C L (scratch resistance) poor perfect without Additive 2% HMW amide PP-MAA based 2% Silicone oil masterbatch 1% Fatty acid amide 2% TEGOMER AntiScratch 100 before ageing after ageing Page | 12 Ageing is Crucial to Evaluate Additives for Car Interior Applications Temperatures in summer in a (closed) car after 1 hour in the sun: Dashboard: up to 80 C Head room: up to 70 C Foot space: up to 60 C To simulate the conditions in a car we do the following testing.

TEGOMER AntiScratch 100 does not show any migration and tackiness in the PV 1306 test. It stays in the bulk phase of plastics compounds and provides a long lasting scratch resistance.
