Abstract
A cannister-based, high solids, low and non-VOC aerosol adhesive and canister based system. The aerosol adhesive typically includes a high solids polymeric base, a hexane or cyclohexane and acetone solvent mixture and a compressed gas dissolved within the solvent. The compressed gas typically includes carbon dioxide, nitrogen, nitrous oxide and air. The aerosol adhesive is adapted to be filled into a cannister including a hose connected to the canister and a spray gun connected to the hose. The system typically includes high solids with a high viscosity. Thus the canister typically maintains high pressures up to 350 psi, but typically at 260 psi while maintaining 325 psi at 130° F., to deliver effective spray patterns.
Claims28
An aerosol adhesive canister system, comprising:
- a gas cylinder canister;
- a hose connected to said canister;
- a spray gun connected to said hose;
- a hydrocarbon propellant held within said canister;
- and
- an aerosol adhesive held within said canister, said aerosol adhesive comprising:
- a solvent mixture selected to have volatility characteristics for producing a specific spray pattern;
- a polymeric base in said solvent mixture;
- and
- a compressed gas dissolved in said solvent mixture.
A spray adhesive canister system, comprising:
- a combination of compressed inert gas and liquefied propellant usable together in said canister, wherein the relative volume and concentration of liquefied propellant is minimal relative to the relative volume and concentration of compressed inert gas,
- wherein said combination and relative concentrations of compressed inert gas and liquefied propellant enables said spray adhesive canister system to maintain a consistent spray delivery pressure and a consistent spray coarseness irrespective of the volume of spray adhesive remaining to be dispensed from said canister, and wherein said spray adhesive is a high solids, high viscosity, low solvent and low voc blend.
