Hyun-Joong Kim and colleagues from the Seoul National University in Korea with cooperation from PPG Industries Inc., Korea researched for an automotive pre-primed system to remove wash and pre-treatment processes using a roll coating application for environmental regulations. Elastomeric polyesters allow a high flexibility and formability to overcome harsh conditions such as cutting, press and stamping processes.

The researchers designed special elasotmeric polymers to improve flexibility and formability in terms of high molecular weight, low crosslink density and content of flexible segment. Furthermore they measured the curing, viscoelastic behavior, flexibility, formability and physical properties of resins to evaluate suitability of the synthesised primers for an automotive pre-primed system.
They found out that high molecular weight and the content of flexible segment are powerful factors affecting the formability for an automotive pre-primed system.
