Adhesion to Steel and Other Materials like PE, PP

STOPAQ has a low surface tension, which implies a good wetting of steel surfaces. Adhesion tests on steel and also on PE, PP showed only cohesive fractures. Diffusion of the visco-elastic polymer into the finest pores of the steel surface, results in an intensive corrosion protection. Due to this cohesive fracture mechanism, the steel surface is not exposed to moisture or oxygen in case defects are inflicted. Furthermore, STOPAQ has the ability to repair defects due to its flowing properties.
