Dispersion adhesives are water-based adhesive systems which form bonds through physical hardening when the water evaporates. The bonding effect is provided by a polymer component which forms a film when the aqueous component evaporates. Depending on the application and chemical basis of the adhesive it may be necessary to add an isocyanate crosslinker or nitrate hardener before processing. This can increase the bond’s resistance to heat and moisture.
Jowat supplies a wide range of powerful Jowacoll® dispersion adhesives used in the wood-processing industry, in the paper and packaging industry, the graphics industry, as well as in the automotive, textile and electrical industries. Dispersion adhesives of the latest generation facilitate high processing speeds with low plant costs. Another major requirement is the appearance of the bondline after film-forming. A high degree of gloss and high transparency of the dispersion adhesive very important, as is the prevention of discoloured joints.
High strength values and also very low in formaldehyde
