A modular system for atomizing and delivering liquids to a substrate. The modular system comprises a liquid module, a means for providing an atomizing agent, a nozzle assembly and an actuator which is changeable between a first closed position and a second open position, for selectively allowing the atomizing agent to flow from the means for providing atomizing agent to the atomizing agent channel and for selectively allowing the liquid to flow from the cavity to the liquid delivery nozzle. The modular system atomizes liquids into a narrow distribution of particle sizes without the use of propellants or solvents. The modular system has replaceable liquid and atomizing agent modules. A method for atomizing liquids is also disclosed.

Modular system for atomizing a liquid

A repositionable pressure-sensitive adhesive comprising from about 70% to about 99% solid, polymeric, acrylate, inherently tacky, infusible, solvent-insoluble, solvent-dispersible, elastomeric microspheres comprising at least one alkyl acrylate or alkyl methacrylate ester; and at least one polar monomer, and correspondingly, from about 30% to about 1% of a binder copolymer comprising an elastomeric polymeric backbone having pendant therefrom high Tg polymeric moieties.

A repositionable pressure-sensitive adhesive comprising from about 70% to about 99% hollow, polymeric, acrylate, inherently tacky, infusible, solvent-insoluble, solvent-dispersible, elastomeric microspheres comprising at least one alkyl acrylate or alkyl methacrylate ester, a majority of the microspheres having one or more interior voids having a diameter of at least about 10% of the diameter of the microsphere, and correspondingly, from about 30% to about 1% of a binder copolymer comprising an elastomeric polymeric backbone having pendant therefrom high Tg polymeric moieties.

Pressure-sensitive adhesive comprising hollow tacky microspheres and

Microencapsulated liquids are applied to substrates from an aerosol applicator. The composition requires selection of solvents, propellants and binders that are not active solvents on the material constituting the capsule shell.

Aerosol application of encapsulated materials

A non-glare, abrasion resistant coating can be produced by spraying a polymerizable composition onto a surface. The composition comprises an epoxy prepolymer of an epoxy-terminated silane and an oxirane comonomer in solution. The composition may be conveniently applied from an aerosol can.
