Improved shear strength*

Acrylates copolymer PSA adhesion properties by product.

  • Higher gel content allowing for better cohesion
  • Enhance adhesion cohesion balance offering wider formulation flexibility

Higher branching level

Exxal alcohol branching carbon numbers.

  • Higher level of branching leading to an increase in abstractable hydrogens

Better water resistance*

Water resistance of copolymer PSA based on contact angle degree.

  • More hydrophobic surface
  • Lower water absorption rate

*Compared with 2-ethylhexanol in formulated acrylate PSAs

Superior water whitening*

  • Maintains transparency
  • Superior water whitening through formulation optimization
