Abstract
A method and composition for waterproofing a substrate includes applying a coating composition to a surface of the structural unit. The coating composition includes a) an organic solvent, b) a hydrocarbon resin and c) a copolymer having styrene and diene monomer units, a polymer having olefin monomer units, or a copolymer having styrene and olefin monomer units, or mixtures thereof.
Claims6
A waterproofing composition, comprising:
- about 33 phr to about 250 phr of an organic solvent;
- about 10 phr to about 50 phr of a polyindene;
- about 50 phr to about 90 phr of a polymer selected from the group consisting of a polymer having olefin monomer units, a copolymer having styrene and olefin monomer units with a styrene-content of about 10 wt. % to about 60 wt. % and mixtures thereof;
- and
- a polymer having styrene monomer units and a styrene content of 60 wt. % or greater.
