Paragraph starter

Research indicates that the effectiveness of coatings on composite and technical polymer substrates is significantly influenced by the chosen surface pre-treatment method. Studies have demonstrated that techniques such as mechanical abrasion, laser texturing, and chemical etching can enhance surface roughness and chemical reactivity, leading to improved adhesion of thermal spray coatings by up to 25% compared to untreated surfaces. This highlights the critical role of surface preparation in ensuring the durability and functional performance of coated components in demanding applications.
