Dow Chemical THE FIRST PATENTED constraining force sensitive adhesives (PSA) were derived from natural rubber for bandages in 1850 new developments in the use of polyurethane dispersions (PUDs) to replace natural rubber in non-allergenic examination glove has sparked interest in their evaluation in PSAs (1) New continuous PU dispersion technology has allowed the creation of novel PUD based on the subject of polyether polyols and methylenediphenyl-diisocyanate (MDI). THE FIRST PATENTED constraining force sensitive adhesives (PSA) were derived from natural rubber for bandages in 1850 new developments in the use of polyurethane dispersions (PUDs) to replace natural rubber in non-allergenic examination glove has sparked interest in their evaluation in PSAs (1) New continuous PU dispersion technology has allowed the creation of novel PUD based on the subject of polyether polyols and methylenediphenyl-diisocyanate (MDI). These PU dispersions are solvent-free high-solids (50 to 60 wt percent) and have submicron-sized particles and admirable stability. The PUDs from this proces have been raise useful for designing PSAs with properties ranging from removable to Want to read the whole article? You can purchase it here. It's quick and easy.... |
