PRESSURE-SENSITIVE ADHESIVE COMPRISING A POLYURETHANE HAVING EXCESS HYDROXYL FUNCTIONALITY; MEDICAL ARTICLES COMPRISING A LAYER OF SUCH ADHESIVE |
摘要 |
Pressure-sensitive adhesives which possess absorptivity and/or permeability properties to remove transepidermal water loss and/or other bodily fluids that come into contact with the adhesive, in combination with a fine balance of cohesion and adhesion properties, can be formulated by controlling the crosslinking of a polyurethane polymer having excess hydroxyl functionality, a glass transition temperature of less than about 0 DEG C, a moisture absorption of at least about 20% of its weight and/or a moisture vapor transmission rate of at least about 300 grams/meter<2>/24 hours measured at 37 DEG C and a 90% relative humidity gradient. Adhesives of these polymers possess a peel adhesion to human skin of between about 0.3 and 4 newtons/cm width of the polymer or adhesive. |
