Abstract:
Algae-resistant roofing granules consisting of one or two coats of a fired semi-ceramic composition having a metallic copper powder which does not significantly affect the color tint strength of the pigment contained in the coatings.
Abstract:
What is described herein is an aqueous dispersion for coating water-soluble granules of a water soluble active agricultural chemical to substantially increase the rain fastness of the active. The dispersion includes by wt. (a) at least 0.1% of a polymeric anionic dispersing agent, (b) 5-30% of a water-insoluble, natural or synthetic inorganic or organic polymer, and (c) to 100% of water.
Abstract:
This invention relates to a reaction product of allantoin and formaldehyde made in a molar ratio of about 1:2.75-1:3.25, preferably 1:3, respectively, preferably under controlled pH (5.0 to 7.0) and temperature (40null to 85null C., preferably 50-60null C.) conditions, which product contains free formaldehyde (
Abstract:
A post-treatment process for making a water-resistant polymeric composition which is inkjet printable, or in the form of a strongly-swellable gel, includes providing a stable, aqueous two-phase polymeric composition by the steps of forming a reaction mixture in a reaction vessel which includes a water-soluble vinyl monomer, optionally with one or more water-soluble comonomers, a first amount of a multi-vinyl crosslinking agent, and water, heating the mixture, then periodically adding a predetermined amount of a free radical initiator, and polymerizing the reaction mixture, optionally removing the resultant two-phase polymeric composition from the reaction vessel, adding a predetermined amount of a post-treatment crosslinker, optionally blending with a proteinaceous or other water compatible polymer material thereto, optionally coating the mixture onto a support, and optionally heating at room temperature or above, to increase the viscosity of the composition in a predetermined manner.
Abstract:
Colored roofing granules and methods for their preparations, having decorative metallic appearance and enhanced stability against discoloration of color containing a silica-encapsulated metallic flake or colored lamellar effect pigment distributed in an insolubilized alkali silicate coating.
Abstract:
A tablet of compacted particulate cleaning composition, wherein the tablet or a discrete region thereof contains surfactant and detergency builder, characterized by containing about 1-10% by wt. of a composite disintegrant blend comprising, by weight, (a) about 40-70% of a water soluble salt, (b) about 30-60% of a mixture of about 10-90% of cellulosic material and 90-10% of crosslinked polyvinylpyrrolidone, said tablet having a disintegration rate of at least 100 g/min.
Abstract:
What is described is a polymeric hydrogel product of a stable, aqueous polymeric composition which composition forms a clear to translucent film upon application to a substrate, and includes, by weight, 5-75% of (a) a water-soluble polymer having (b) in situ-formed, substantially water-insoluble resinous particles of said polymer substantially uniformly dispersed therein, and (c) 25-95% of water, made by irradiating the composition with high energy electron beam or gamma-radiation.
Abstract:
An aqueous dispersion of (a) 0.1-40% by wt. of a low molecular weight, low melting point, water-insoluble polymer in which the polymer particles have a size
Abstract:
A tablet coating composition including a mixture of (a) sodium alginate and (b) a polyvinylpyrrolidone-vinyl acetate copolymer, and, optionally, (c) hydroxypropylmethyl cellulose, and/or hydroxypropyl cellulose.
Abstract:
A method of enhancing the efficacy of a polymeric wax inhibitor for an oil which comprises applying said inhibitor in an aliphatic glycol ether solvent.
