Study on Surface Treatments of Modified Wood Plastic Composite (WPC) to Improve Adhesion

Article Preview

Abstract:

The presented case study is focused on the complications that affect the adhesion properties of wood plastic composites. In an effort to improve the physical properties of the WPC and the adhesive bonding between the selected material and adhesive systems intended for façade bonding, several surface pretreatments were performed. The surface modification consisted of mechanical roughening or physical treatment with diffuse coplanar surface barrier discharge. The shear strength of the adhesive bond was tested following ČSN EN 1465 and the maximum shear stress was calculated for each treatment method. Although, the increase in bond strength due to these treatments was measured only for one tested adhesive system where the strength was increased by 100% with respect to the control, the diffuse plasma treatment improved the adhesive bondability and a change in failure mode was observed in all tested cases.
