High performance liquids have applications in rigid vinyl and vinyl-ABS; TM220 reduces stress-whitening and maximizes impact; TM-303 and -306 have low mercaptide odor and good clarity when compounded for PVC bottles Line of adsorbents has use in both thinlayer and column chromatography; includes acid, basic, and neutral aluminum oxide, magnesium silicate, polyamide, acetyl cellulose, and silica gel Synthetic fluid catalyst produces as much as 4 % more gasoline than lowerpriced catalysts; high content of rareearth-exchanged Y-type molecular sieves; good attrition resistance, uniformity, low contaminant level Cationic substance settles on pond bottom and reduces seepage by up to 7 0 % ; needs no special mixing equipment; effective over wide range of water and soil types; nontoxic to humans and animals N,N-bis(2-hydroxyethyl)alkyl amine imparts antistatic properties to polyethylene and polypropylene; alkyl distribution C12, C14, and C16 components, but mostly C14; chemical uniformity; no isomers Plastic coating increases fabric's wear resistance without imparting additional bulk or stiff feel; upon application plastic surrounds each fiber to provide protective covering; coating breathes to avoid discomfort in warm weather Substance is effective and economical cleansing agent for injection molding and extrusion machines; purges all types of thermoplastic resins; good color absorption properties; melt viscosity in excess of 600° F. Tungsten disulfide aerosol can be used in air to 1600° F. for short periods and to 950° F. in air continuously; low friction coefficients; lubricates to very high pressures; protects against corrosion; stable to most acids and caustics High-strength adhesive bonds wood, leather, nylon, cotton, paper, rubber, metals, plastics, and concrete; viscosity of 110 to 150 centipoise; peel strength of 10 pounds per sq. in., minimum; shear strength of 100 pounds per sq. in., minimum; flexible Substance develops strong fluorescence with protein solutions permitting direct use of fluorometry in electrophoresis scanning; significantly reduces scanning time
