Abstract
A reactive pressure sensitive adhesive composition which comprises at least one material selected from the group consisting of saturated polyester resins, acrylic rubbers, acrylic elastomers, polybutadienes and acrylic pressure sensitive adhesives which are all non-flowable at normal temperature and at least one reactive compound selected from the group consisting of (meth)acrylic urethane monomers, oligomers thereof, other (meth)acrylate monomers and oligomers thereof, and sealer tape, sheet or molding which includes the composition.
Claims10
A sealer tape, sheet or molding which comprises a non-solvent based reactive pressure sensitive adhesive composition having tackiness under ambient conditions and having tough or elastic physical properties after curing, said pressure sensitive adhesive further having a thickness between approximately 25 .mu.m and 1 cm, comprising a saturated polyester resin which is non-flowable at 5.degree. C. to 35.degree. C., a (meth)acrylic urethane oligomer having a viscosity of 10.sup.2 cps or higher at 5.degree. to 35.degree. C. and a heat-curable catalyst, said adhesive composition being applied onto a substrate surface or a mold surface which has been optionally subjected to a releasing agent treatment.
