Taber tests are designed to measure a material’s capacity to withstand abrasion and its effects during operation. Conformal coatings – both liquid and parylene (XY) – are

The Need for Adhesion Testing
Applied mechanical processes stimulate the binding force between surface molecules required for parylene adhesion to substrates, which is essential to both good parylene performance and assembly/component functionality. The emergence of conditions characterized by non-adherence and delamination squander parylene’s typically exceptional substrate protection against chemical attack, corrosion and moisture, as well as its superior dielectric insulation (er = 3.1).
