Techniques for Measuring Adhesion and Abrasion Durability of Coatings and Ink
By Scott Sabreen Adhesion and abrasion durability of cured coatings and inks are two critical performance properties. These properties can be interdependent but often are mutually exclusive. That is, cured coatings and inks can demonstrate good adhesion and poor abrasion, or poor adhesion and good abrasion. Proper testing and understanding of adhesion and abrasion ensures [...]
Surface Wetting and Pretreatment Methods
By Scott Sabreen, The Sabreen Group Plastics adhesion problems are widespread throughout the industry. A major contributing factor to these problems is that many plastics have chemically inert and nonporous surfaces with low surface tensions. That is, most plastics are hydrophobic and are not naturally wettable. These properties, although advantageous to the design engineer, often [...]
