Claims
- 1. An adhesive compound consisting essentially of a latex, a process oil, a tackifying resin and water, wherein an elastomeric component of said latex is selected from the group consisting of styrene butadiene, acrylic homopolymers, acrylic copolymers, acrylonitrile butadiene, polychloroprene, vinyl acetates, ethylene vinyl acetate copolymers, carboxylated styrene butadiene, and combinations of these elastomers, wherein said adhesive compound has a total solids content in the range of greater than 72%.
- 2. The adhesive compound of claim 1, wherein said tackifying resin comprises at least one of the group consisting of: C9 resin, wood rosin, ester of rosin and pentaerythritol ester of rosin.
- 3. The adhesive compound of claim 1, wherein said process oil comprises at least one member of the group consisting of: a severely hydrotreated petroleum hydrocarbon oil, having predominantly hydrocarbons with carbon numbers in the range of C20 to C50; and a naphthenic process oil.
- 4. The adhesive compound of claim 1, wherein said latex is styrene butadiene latex having total solids in the range of 65-75%.
- 5. An adhesive compound comprising:
- 35-45 wt. % of cold high solids styrene butadiene latex buffered to a pH of 11.0 using a caustic agent;
- 25-55 wt. % of a resin cut consisting essentially of naphthenic rubber process oil, a tackifying resin, and an anti-oxidant; and
- the balance water;
- wherein said adhesive compound has a total solids content in the range of greater than 72%.
- 6. The adhesive compound of claim 5, wherein said process oil comprises severely hydrotreated petroleum hydrocarbon oil, having predominantly hydrocarbons with carbon numbers in the range of C20 to C50.
- 7. The adhesive compound of claim 5, wherein said tackifying resin comprises at least one of the group consisting of: C9 hydrocarbon resin, wood rosin, ester of rosin and pentaerythritol ester of rosin.
