Abstract
A article for wrapping objects comprising a plurality of layers, including a first layer of a wrap material, an intermediate layer of an adhesive material and an inner layer of a solids material, said article providing resistance to cathodic disbondment from said object at least equal to an adhesive bearing wrap applied with a solvent based primer.
Claims6
An article for wrapping objects, said article comprising a plurality of layers, including:
- a first layer of a wrap material;
- an intermediate layer of a flexible, adhesive material;
- and
- an inner layer of a flexible solids material, said solids material being comprised of:
- (a) from 10 to 55 weight percent thermoplastic elastomer;
- (b) from 27 to 75 weight percent resin material;
- (c) from 0 to 25 weight percent polyolefin;
- and
- (d) from 0 to 3 weight percent anti-oxidant,
- where said thermoplastic elastomer is selected from the group consisting of SIS or SEBS tri-block copolymers, SEP or SEB di-block copolymers and styrene-butadiene branched block copolymers, where S is a polymeric styrene block, B is a polymeric butadiene block, I is a polymeric isoprene block, EP is a polymeric ethylene/propylene block and EB is a polymeric ethylene-butylene block;
- n>1;
- where said resin material is selected from the group consisting of white mineral oil, phenolic resin and a phenolic-modified terpene resin;
- where said polyolefin is selected from the group consisting of naphthenic oil and naphthenic oil modified with a filler;
- wherein said article provides resistance to cathodic disbondment from said object at least equal to an adhesive bearing wrap applied with a solvent based primer.
