1. A pressure-sensitive adhesive copolymer composition comprising a reaction product consisting of:
60 to 85 weight % of vinyl ester of 2-ethyl hexanoic acid, and one or more compounds selected from the group consisting of vinyl acetate, (meth)acrylate, (meth)acrylic acid, a vinyl ester of C3 to C18 carboxylic acid, and combinations thereof, wherein the total weight % of the copolymer is 100 weight % and wherein, when applied, comprises an adhesive layer having at least: a. a 180° peel of from 7.5 N/25 mm to 10 N/25 mm, as measured by FTM-1 on stainless steel at room temperature after 24 hours; b. a 180° peel of from 3.5 N/25 mm to 6 N/25 mm, as measured by FTM-1 on polyethylene at room temperature after 24 hours; c. a 180° peel of from 7.5 N/25 mm to 12 N/25 mm, as measured by FTM-1 on glass at room temperature after 24 hours; d. a shear holding of more than 5000 minutes, as measured by FTM-8 on stainless steel at room temperature after 24 hours; or e. a loop-tack test of from 3 N to 10 N, as measured by FTM-9 on stainless steel at room temperature after 24 hours or wherein, when applied, rises an adhesive layer having at least: a. a 180° peel of from 7.5 N/25 mm to 15 N/25 mm, as measured by FTM-1 on stainless steel at room temperature after 24 hours; b. a 180° peel of from 3.5 N/25 mm to 15 N/25 mm, as measured by FTM-1 on polyethylene at room temperature after 24 hours; c. a 180° peel of from 7.5 N/25 mm to 15 N/25 mm, as measured by FTM-1 on glass at room temperature after 24 hours; d. a shear holding of more than 500 minutes, as measured by FTM-8, on stainless steel at room temperature after 24 hours; e. a loop-tack test of from 3 N to 10 N, as measured by FTM-9 on stainless steel at room temperature after 24 hours; or f. a 180° peel of from 2N/25 mm to 7.5N/25 mm, as measured by FTM-1 on Teflon at room temperature after 24 hours. |
