TECHNOLOGY FOCUS - POLYMERS - Preferred Resin: The polymeric resin is chlorinated polyvinyl chloride, polyvinyl chloride, acrylonitrile styrene butadiene resin and/or acrylic resin.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The composition preferably contains (in weight %):(i) tetrahydrofuran (26);(ii) cyclohexanone (7);(iii) butyrolactone (5);(iv) acetone (26);(v) aerosol propellant (30);(vi) viscosity modifier/flow control agent (3.5);(vii) organotin compound (0.5); and(viii) polymer resin (14.5).The aerosol weld cement further includes a dye compound.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Compounds: The viscosity modifier/flow control agent is silica and/or clay. The organotin compound is alkylated tin (IV) compounds, di butyltin di laurate, di-n-octyltin di mercaptide, di butyltin thioesters, di-n-octyltin maleate, di butyltin carboxylate or di butyltin dithiol. SPECIFIC COMPOUNDS - The solvent is specifically claimed as tetrahydrofuran, cyclohexanone, butyrolactone and/or acetone.    The propellant is specifically claimed as dimethyl ether, propane, butane and/or isobutane.    EXAMPLE - A mixer was charged with tetrahydrofuran (30 lbs) and chlorinated polyvinyl chloride resin (14.4 lbs). The components were mixed for 15-30 minutes at low speed, and checked for resin cut in. The mixer was added with fumed silica of AEROSIL 200 (4.9 lbs) and mixed until the formation of a homogeneous mixture. The mixer was sequentially charged with an additional tetrahydrofuran (7 lbs), butyrolactone (7 lbs), cyclohexanone (10 lbs), acetone (26 lbs) and ADVASTAB TM-161 (RTM, methyltin mercaptide) (0.6 lbs). The mixing was continued till the formation of an homogeneous mixture, and the mixture was checked for solid and viscosity levels. The solid content was adjusted using a solvent mixture comprising 60 % of tetrahydrofuran and 40 % of acetone, to 19 +/- 2 %. A dye Keystone Purple 706-404-40 (RTM) (182.1 g) was added per 50-gallon drum of solvent weld cement. The solvent weld cement was filtered, packed into aluminum aerosol containers with propellant and 30 weight % (wt.%) of dimethyl ether, and tested for storage stability.    The solvent weld composition was found to be 100 % stable and free of gelling after 90 days. The solvent weld was found to be compatible with an aerosol unit. The solvent weld cement could be easily, quickly and uniformly applied using one hand, resulting in a longer working time. The cement was dispensed from a container which protects cement from solvent evaporation, oxidation and physical contamination, and was found to resist environmental pollution by preventing unwanted spills.
