Abstract
An adhesive and coating composition which is suitable for use in an aqueous environment is provided and which comprises a resin-plasticizer modified acrylonitrile-butadiene elastomer, dissolved in low-toxicity solvent. A method for repairing plastic sheet materials, particularly plastic sheet materials such as polyethylene (LDPE, MDPE), polypropylene (PP), polyvinyl chloride (PVC) and polyvinylidene chloride (PVDC),using the adhesive and coating composition wherein certain controls are effected is also provided. Such an adhesive composition provides a fast and extremely effective means for repairing perforations and tears in plastic sheet materials, is long lasting, safe and does not discolor over time.
Claims29
An adhesive composition especially suited for underwater application and comprising:
- a thermoplastic resin and plasticizer modified acrylonitrile-butadiene elastomer wherein the acrylonitrile-butadiene elastomer is in an amount between 1-22% by weight of the total adhesive composition, wherein the resin is a terpene phenolic resin in an amount between 1-22% by weight of the total composition and the plasticizer is in an amount between 1-15% by weight of the total composition;
- and a low-toxicity solvent.
A method for preparing a solvent based adhesive comprising:
- dissolving an acrylonitrile-butadiene copolymer having an acrylonitrile content of between approximately 15-45%, in a low-toxicity solvent, to produce a solution;
- adding a thermoplastic terpene phenolic resin and a plasticizer to the solution;
- and
- subsequently blending so as to produce a solvent based adhesive composition containing a resin and plasticizer modified acrylonitrile-butadiene copolymer;
- wherein the adhesive composition bonds and seals plastic sheet materials in underwater applications.
An adhesive composition especially suited for underwater application and consisting essentially of a simple admixture of a solvent solution of an acrylonitrile-butadiene elastomer, a terpene phenolic resin and a plasticizer, wherein the acrylonitrile-butadiene elastomer is in an amount between 1-22% by weight of the total adhesive composition, the resin is in an amount between 1-22% by weight of the total composition and the plasticizer is in an amount between 1-15% by weight of the total composition, and the solvent is a low-toxicity solvent.
