Plasticizer-resistant water-based pressure sensitive adhesives for PVC substrates
It has also been confirmed that the amount of formaldehyde emitted is equivalent to F☆☆☆☆, so it can be used with confidence in interior materials for indoor applications.
Technology to suppress decrease in adhesive strength by preventing plasticizer migration
Adverse effects of plasticizers on pressure sensitive adhesives
- PVC: polyvinyl chloride (PVC)
- Plasticizer: Additive to soften resin such as PVC
Plasticizer resistance technology
By using a special composition design that differs from conventional water-based pressure sensitive adhesives, we have succeeded in preventing the plasticizer contained in the PVC base material from migrating to pressure sensitive adhesives and suppressing the decline in adhesive strength.
Plasticizer-resistant water-based pressure sensitive adhesives
Adhesive strength comparison data over time
If a general-purpose water-based pressure sensitive adhesives is used for adhesive coating samples on PVC substrates, the adhesive strength will decrease significantly over time.
When using the new products BPW 6613 and BPW 6614, it is possible to suppress the decrease in adhesive strength to a greater extent than with solvent-based plasticizer-resistant pressure sensitive adhesives.
- Coating amount: 16±1g/m2, Base material: PVC film (contains 15% plasticizer), Curing: 1 week at room temperature, Adherent: Polished SUS, 24 hours after application
Product features
- Since it does not contain organic solvents, it is environmentally friendly, can be used in products for indoor applications, and also contributes to improving the working environment.
- External agency tests have confirmed that the amount of formaldehyde emitted is equivalent to F☆☆☆☆.
- Since it is a one-component type, there is no need for a curing agent compounding process.
