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 25 μm → 5 μm
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.
- 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
| thermosetting type | UV curing type | |
|---|---|---|
| Features | ・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.
