Japan develops 99% adhesive with ultra-high solid content.

Toyochem, a subsidiary of Japan's Toyo Ink Group, announced that it had developed a new range of polyurethane pressure-sensitive adhesives with ultra-high solid content of 99% or more.
said the new adhesive composition is comparable to the performance of conventional solvent-based pressure-sensitive adhesives, while keeping the content of solvents and volatile substances to a minimum and can be used in a wide range of industrial applications, such as protective films.
Toyochem has been developing a range of adhesive compositions with high solid content and high non-volatile components to meet market demand for low VOC

.
a unique synthesis method
in general, the more solids the adhesive composition contains, the higher the viscosity and the more difficult it is to coat. To solve this problem, Toyochem researchers use the company's unique polymer and crosslink design technology to control chemical reactivity while maintaining the high performance of adhesives as they develop new formulations with low viscosity and high solid content.
addition, the company uses a unique synthesis method to reduce the solvent content of adhesives to very low levels. Toyochem uses these new technologies to prepare adhesive formulations with a solid content of nearly 100% with a high degree of transparency, good construction and air release, comparable to traditional pressure-sensitive adhesives. At present, the pressure-sensitive adhesive has been listed in Japan, in the next few years will be available worldwide.
