What Is a Powder Adhesive?
Powder adhesive is a type of adhesive that comes in a fine powder form, eliminating the need for water or solvents during the bonding process. Its composition primarily includes resin, a curing agent, fillers, and various additives. The powder is applied directly to the bonding surface and then cured through heat or pressure, resulting in a durable adhesive film. This adhesive is especially valuable in bonding metals, plastics, ceramics, and glass, and finds extensive use in construction and civil engineering.
Notable for its low environmental impact, powder adhesive offers strong bonding capabilities across a wide range of materials, along with heat and chemical resistance, and satisfactory workability. However, due to its powder form, adequate ventilation and protective masks may be necessary during application to manage the curing process, and bonding time, and minimize the inhalation of airborne particles.
