The new high-solids system reportedly contributes to reduced carbon dioxide gases during coating and drying processes for a safer, more environmentally sound work environment.
Toyochem Co., Ltd., a member of the Toyo Ink Group, has developed a new Cyabine™ series of polyurethane pressure-sensitive adhesives (PSAs) with an ultra-high solids content of 99% or more. The new adhesive composition reportedly achieves the same performance levels as conventional solvent-based PSAs while reducing solvent and volatile content to minimal levels. The adhesives are suitable for use in a wide range of industrial applications, such as protective films.
In recent years, countries around the world have been taking urgent action to mitigate climate change and its impact. This is also true in the field of adhesives, where much research is being conducted in the area of renewable materials derived from bio-based polymers. While petroleum solvents had been extensively used in adhesive systems of the past, there has been a growing call to reduce or eliminate the solvent content as a countermeasure to address environmental concerns.
