Acrylic water-based pressure sensitive adhesives for low-temperature bonding Can be used sub-zero climate

This is an acrylic water-based based pressure sensitive adhesives with excellent adhesion in low-temperature environments such as cold regions. It has a one-component water-based design that is environmentally friendly and requires no mixing process, and exhibits good adhesion and anchoring properties to various adherends and base materials.

Pressure sensitive adhesives in low temperature environments

In general, even if pressure sensitive adhesives exhibits high adhesive properties at room temperature, when used in winter or in a low-temperature environment, its performance as an adhesive tends to deteriorate, such as poor adhesion to pressure sensitive adhesives there is.

The new product we are introducing today is an acrylic water-based based pressure sensitive adhesives with excellent adhesive properties in low-temperature environments.
It exhibits good adhesion even when applied in cold environments or in low-temperature environments such as inside a refrigerator.

Anchorability to adherends. If pressure sensitive adhesives is hard at low temperatures, it will not wet the adherend and will not provide adhesive strength, but BPW6681 is soft even at low temperatures and sufficiently wets the adherend to provide adhesive strength.

Acrylic water-based based pressure sensitive adhesives for low temperature adhesive BPW 6681

Characteristics

It exhibits good adhesive strength even when pasted in negative environments.
It has high adhesion and adhesion to various adherends and base materials that are difficult to anchor, such as foam.
It is an environmentally friendly product as it is a water-based pressure sensitive adhesives that does not contain solvents.
Since it is a one-component curing type, there is no need for a compounding process.
Production is possible not only in Japan but also at our base in China.
