BYK-TS 3200 and BYK-TS 3201: Additives That Improve Scratch Resistance of Polyolefin-Based Surfaces and Components

Polyolefins are used in numerous applications, including the automotive industry, due to their excellent moldability and processability, efficiency and overall suitability. These attractive properties have sometimes led them to replace other technical solutions.

However, sometimes these materials do not fully reach their capacity to provide more sophisticated solutions. Certain deficiencies exist, particularly when it comes to scratch resistance of polyolefin-based component surfaces. Nevertheless, it is possible to improve these deficiencies by using certain additives. With BYK-TS 3200 and BYK-TS 3201, BYK presents two additives that significantly increase scratch resistance of thermoplastic components by reducing scratch depth and visibility of scratches. Components produced using BYK-TS 3200 and BYK-TS 3201 maintain their visual quality over a long period. In the image below, you can see the responses of material without additive and material with 1.5% BYK TS 3201 added to forces applied at different Newtons.

Benefits

• Provides significant increase in scratch resistance of polyolefin-based surfaces and components, • Odorless, • Effective even at low dosages, • Economic solution, • Supplied in solid form, • Easy to add and process.
