Impregnating liquid for wood and wood products containing a reaction product between tributyl tin oxide and one or more naphthenic acids and a non-oxidative drying binder comprising a polydiene resin. Said impregnating liquid can further comprise 2,4,5,6-tetrachlorisophthalonitrile.

A ready-mixed wallpaper paste comprising a blend of starch, dextrin, water and a hydrophilic colloid, a fungicide and/or bactericide may be included in the blend. The starch and dextrin are first mixed with each other and with the fungicide and bactericide used. The mixture is then blended into water. The blend is weighed and approximately 0.3 percent by weight of the blend of the hydrophilic colloid is then added to the blend.

Described is a composition of wood, or wood-derived matrix and one or more lanthanide elements of lanthanide element derivatives bonded to the matrix, a method of making the composition and a method of use. The composition is useful as an antifouling additive in paints.

A method for reducing cavitation around underwater acoustic projectors is described. The projector is cleaned with a surfactant and then encapsulated with an aqueous gel containing a polysaccharide polymer such as a chitosan derivative, a hydrophilic stabilizer and a biocide.

A composition for coating a water-contacting surface for reducing kinematic friction, preventing corrosion and blistering, reducing water impact noise, and absorbing water shock includes a polymer including a polyhydroxystyrene of the novolak type. In alternate embodiments the composition also includes an antifouling agent, a gel coating material, and/or an epoxy. A method includes coating a water-contacting surface with the composition, preferably in a solution in an appropriate solvent, such a...

Heat transfer surfaces in condensing heat exchangers are often coated with a hydrophilic coating to provide wetting and wicking. This coating is typically porous and continuously moist during operation and, therefore, a potential breeding ground for microbes. The inclusion of an antimicrobial agent, such as silver oxide, in the coating inhibits microbial growth and improves adhesion to the heat transfer surfaces.

A wood preserving impregnating oil with improved leaching, evaporation, and exudation characteristics comprised of: 10-100 weight % of coal conversion oil, 0-90 weight % of coal tar impregnating oil, 0-75 weight % of mineral oil fraction in the boiling range of 200.degree.-400.degree. C., 0-60 weight % of alkyl- or cycloalkyl-substituted aromatics with 2 to 4 rings.

What are disclosed are methods for rendering a substrate such as wood biocidal by treating the substrate with a biocidal triorganotin compound of the formula ##STR1## wherein R is cyclohexyl, phenyl, or alkyl having from 3 to 8 carbon atoms.

The formation of carbon on metals exposed to hydrocarbons in a thermal cracking process is reduced by contacting such metals with an antifoulant selected from the group consisting of tin, a combination of tin and antimony, a combination of germanium and antimony, a combination of tin and germanium and a combination of tin, antimony and germanium.

There is disclosed a wood preservative system of from 2 to 15 percent, preferably 8 to 12 percent by weight of a tributyl tin ester selected from the group consisting of tri-n-butyltin linoleate, Bis(tri-n-butyl)tin succinate, tri-n-butyl tin benzoate, tri-n-butyl tin salicylate and mixtures thereof, in an organic solvent system or a water base system, preferably a water base system, for controlling algae, fungi, shipworms, gribbles, barnacles and other wood deteriorating organisms and the like ...
