| Résumé : |
Waterbased pressure sensitive adhesives differ from solvent-based PSAs in many respects. Differences in manufacturing equipment, end-product markets, production styles (batch processing versus dedicated lines), and chemistry must be considered when deciding whether to convert solvent-based products and processes to the use of waterbased adhesives. Although waterbased PSAs may be formulated for nearly any adhesive category (i.e., natural rubber, styrene-butadiene copolymers, butyl rubber, acrylic, etc.), most advances in waterbased PSA technology have occurred in the acrylic category. For this reason, most of the discussion in this article is primarily applicable to comparisons between waterbased acrylic and solvent-based PSAs.
The acceptance of early waterbased acrylics was slowed by problems associated with their adaptability to conventional coating equipment including poor mechanical stability, streaking or channeling of coating, poor wetout on release liner, and high levels of foaming. More recently, advances have been made to ease the transition from solvent-based to waterbased acrylic PSAs.
The purpose of this article is to provide an understanding of the technological considerations associated with the retrofit of solvent-based coating equipment to produce waterbased adhesive-coated products. |
