However, choosing the proper resin can help to extend the working life of acrylic coatings and adhesives and improve the overall performance of the system. Elvacite® Acrylic resins have long been a leader in manufacturing quality acylic resins used in coatings and adhesives for plastics, metals, concrete, wood, & paper. Recently, Dianal has released some new grades specifically targeted at improving adhesion to difficult substrates like metals and plastics.
Metals such as aluminum, steel, copper, and zinc are frequently used in challenging environments that require a protective coating to prevent corrosion and rust. Adhesives that bond metal are also gaining popularity as stress on joints can be distributed across the bond line rather than concentrated at fastening sites. Bonding to metal can be tricky and most of the time light sanding and a primer are necessary. Elvacite® 4347 provides outstanding adhesion to untreated and unprimed metals. It also has the flexibility, outdoor durability, and abrasion resistance needed for the most challenging applications and environments.
