Example of use

Application examples of functional heat seal adhesives (automobiles, building materials)

A heat-curing adhesives has superior heat resistance and durability than conventional products, and maintains high adhesion even in harsh environments.After coating and drying, it can be rolled up without a separator (release paper), making it ideal for thermal adhesive films.

Characteristics

Excellent adhesion to various base materials (metals, polar base materials, etc.)
Excellent heat and humidity resistance, weather resistance, and moldability
Coloring and curing temperature can be changed according to your request.

Lineup

In addition to regular products, we also have a lineup adhesives that can be bonded at low temperatures.
