A pressure sensitive adhesives made of natural materials that adheres tightly

Based on the resin design and compounding technologies that TOYOCHEM has cultivated over the years, we have developed biomass pressure sensitive adhesives as a new environmentally friendly product.
It is an environmentally friendly biomass pressure sensitive adhesives that does not have to choose the substrate (attachment partner) that is not found in conventional products.
It is a one-component strong adhesive type that does not require aging.

Product features

Non-edible biomass raw materials are used as the main ingredient

For the sustainable growth of humankind, biomass raw materials that are not directly linked to food problems are indispensable. Therefore, we have developed a pressure sensitive adhesives whose main component is non-edible biomass raw materials using "inedible plants" (plants that cannot be eaten).

Biomass pressure sensitive adhesives

Exhibits strong adhesive strength even on materials such as PE and PP

As a recent trend, there is a movement to use a lot of resin materials in the automobile, consumer goods, and electronics industries for the purpose of reducing the weight of materials. Until now, biomass pressure sensitive adhesives has had a problem of weak adhesive strength on materials such as PP, but the product we have developed this time has a strong adhesive strength on materials such as PE and PP by eliminating the trade-off between adhesion and cohesion.

Contributes to time reduction and reduction of work errors

Conventional acrylic and urethane biomass pressure sensitive adhesives are two-component products and require aging after coating, but since the newly developed product is a pressure sensitive adhesives rubber biomass and a one-component product, it is possible to exhibit strong adhesion to a variety of substrates without the need for aging after coating.

Comparison of physical properties

Adhesive force

The developed products A and B have the feature of exhibiting high adhesive strength regardless of the substrate, and the developed product C is an ultra-strong viscosity grade for SUS and PP that has never been seen before.

Z: zipping (a phenomenon that makes a jittery sound when peeling off)

Base material: 50μm PET
Application amount: 25g/m2 (DRY)

Holding force

Since the developed product does not require aging, it exhibits high cohesion immediately after coating.

Aging condition: 23°C-50%RH 7 days
NC: No misalignment

Base material: 50μm PET
Application amount: 25g/m2 (DRY)
