FEATURE
Substance produces fire-retardant rigid urethane foams which compare well with regular foams in insulation efficiency, strength, and dimensional stability Substance increases efficiency of glass filter fabrics (bags or tubes) operating at temperatures above 600° F.; increases resistance to failure from fabric flexing 4-Chloro-2-cyclopentyl phenol is germicide for detergent-disinfectant formulations; effective against most pathogenic bacteria and fungi found in environmental sanitation Powdered PVC substance is used for high-speed coating operations; hot dipping, rotational molding, and slush molding uses; relative viscosity of 2.65 Substance is visual indicator for rapid volumetric determination of sulfate ions in solution by direct titration with barium perchlorate; sharp end-point not affected by pH Acrylate-based liquid produces light, finely divided, nonadherent particles which are easily removed by boiler blowdown Polyurethane-based elastomer in solution is coating for paper, fabric, vinyl, and rubber products; 3 5 % total solids Modified terphenyl fluid is used as heattransfer medium in temperature range of 15° to 650° F. in nonpressurized, liquid-phase systems Liquid and powdered substances are respectively the butyl and methyl esters of a crotonic acid derivative; absorb UV portion of daylight; impart long lasting protection to coating films, molded articles Liquid material reduces moisture content of mineral filter cakes; improves release properties of filter cake from filter cloth, speeds drying time, and improves pelletizing capabilities Four viscosity grades have good solubility and compatibility, chemical resistance, good adhesion and high abrasion resistance; applications in traffic and swimming pool paints, adhesives, paper coatings, masonry, printing inks. General-purpose, nonblooming antioxidant gives improved heat resistance in most synthetic and natural polymers; powder or flake Complete line of color concentrates in polycarbonate can be used in low-, medium-, and high-viscosity polycarbonates or ABS-polycarbonate copolymers
