Sprayable and aerosolizable webforming compositions

Abstract

Abstract THERE ARE DISCLOSED SPARYABLE AND AEROSOLIZABLE WEBFORMING COMPOSITIONS FOR FORMING SELF-SUPPORTING, THREE DIMENSIONAL WEBS OF RANDOMLY ASSOCIATED, JOINED MONOFILAMENTS RANGING IN AVERAGE DIAMETER FROM ABOUT 1 TO 10 MICRONS, THE SPRAYABLE WEB-FORMING COMPOSITIONS COMPRISING A WATER-INSOLUBLE HYDROCARBON ELASTOMER, AT LEAST ONE WATER:INSOLUBLE RESIN OF HYDROGENATED ROSINS AND POLYOL ESTERS THEREOF, PHENOLIC RESINS, HYDROCARBON RESINS OR COUMARONE-INDENE RESINS COMPARTIBLE WITH SAID ELASTOMER, AND SOLVENT COMPARTIBLE WITH SAID ELASTOMER AND SAID RESIN, AND THE AEROSOLIZABLE WEB-FORMING COMPOSITION COMPRISING, IN ADDITION TO THE COMPONENTS STATED FOR THE SPRAYABLE WEB-FORMING COMPOSITIONS, A PROPELLANT INERT TO SAID ELASTOMER, RESIN AND SOLVENT. THE SPRAYABLE AND AEROSOLIZABLE WEB-FORMING COMPOSITIONS MAY CONTAIN ENCAPSULATED COMPONENTS, E.G., COLORING AGENTS, PERFUMES OR OTHER SCENTS, E.G., INSECT SEX ATTRACTANTS, AGRICULTURAL CHEMCALS, INSECTICIDES, ECT. A PLASTICIZER CAN BE INCLUDED IN THE AEROSLIZABLE FORMULATION TO IMPART INCREASED TACKINESS TO THE WEB OVER EXTENDED TIME PERIODS. THE WEB-FORMING POLYMER SOLUTIONS OR DISPERSIONS CAN BE DISPENSED FROM VARIOUS TYPES OF DISPENSING SYSTEMS AND EQUIPMENT, E.G. FROM SPARY GUNS, PORTABLE AEROSOL CANS, ECT. TO PROVIDE AN ADVANTAGEOUS WAY OF DISPENSING AGRICULTURAL TREATING AGENTS OR OTHER ENCAPSULATED MATERIALS ONTO PLANTS OR OTHER DESIRED REPOSITORIES OR LOCATIONS WITHOUT INTERFERING THEREWITH, E.G. WITH PLANT GROWTH OR METABOLIC PROCESSES THEREOF.
