Abstract
This invention relates to a novel pressure sensitive adhesive formed of a liquid and solid rubber which is substantially resin free. Preferably the adhesive is formed of a weight ratio of solid rubber to liquid rubber of about 1:0.5 to about 1:7. These adhesives exhibit improved adhesion in cold weather and oily surface applications and other properties. The pressure sensitive adhesives can be used in health care, industrial and drug delivery systems.
