Environmentally friendly pressure sensitive adhesives to achieve strong peel strength by lower coating weight

This is a new environmentally friendly pressure sensitive adhesives has high adhesive strength even in a thin film that is 1/5th the thickness of conventional adhesives. Contributes to resource conservation and _CO2 reduction.

Advantages of thinner pressure sensitive adhesives

We have developed a new environmentally friendly pressure sensitive adhesives that has high adhesive strength even with a thin film thickness, which was difficult to do with conventional pressure sensitive adhesives.

Benefit 1: Contributes to resource conservation

Because pressure sensitive adhesives layer is thinner, it contributes to resource conservation, such as by reducing the amount of raw materials used during production.

pressure sensitive adhesives layer is one-fifth thinner than existing products, contributing to resource conservation.

*In case of pressure sensitive adhesives 25μm → 5μm

Benefit ②: Contributes to reducing CO ₂ emissions

Because pressure sensitive adhesives layer is thinner, CO ₂ from raw materials generated during production and CO ₂ generated from combustion during disposal can be significantly reduced.

Because pressure sensitive adhesives layer is thinner, CO2 emissions are reduced by approximately 80% compared to existing products.

The CO ₂ emissions of the existing 25μm product is 0.283g/m2 as 100.
Raw material procurement and combustion: We preferentially use IDEA version 2.2 [Climate Change IPCC 2013 GWP 100a], but some calculations are based on our own rules.

New product lineup

Traditionally, there was a trade-off between "thinning the film" and "adhesion to SUS and PP". With this new product, we have solved two problems by controlling viscoelasticity and interfacial adhesion with thin films in mind, and succeeded in achieving both thin film and adhesive performance.

	thermosetting type	UV curing type
Characteristics	・Exhibits high adhesion to both SUS and PP	・No aging required due to UV curing ・Exhibits high adhesion to both SUS and PP

Development product data

We compared it with existing solvent-based acrylic pressure sensitive adhesives (our STD product).
Even with a film thickness of 5 μm, the developed product shows the same adhesive strength as the existing product with a film thickness of 25 μm.

Compared to existing products, it has the same adhesive strength for SUS and PP.
