CONTROLLED RELEASE, WOOD PRESERVING COMPOSITION WITH LOW-VOLATILE ORGANIC CONTENT FOR TREATING IN-SERVICE UTILITY POLES, POSTS, PILINGS, CROSS-TIES AND OTHER WOODEN STRUCTURES
Disclosed herein are compositions including a dispersion of solid particles of a substantially insoluble copper compound, and an organic biocide, wherein at least 20% of all particles of the composition have a particle size greater than 25 microns. Also disclosed herein are methods of making and using the same.
Controlled release, wood preserving composition for treating in-service utility poles, posts, pilings, cross-ties and other wooden structures
Disclosed herein are compositions comprising a dispersion of solid particles of a substantially insoluble copper compound; a boron-containing compound, a fluoride-containing compound, or a combination thereof; wherein at least 20% of the particles of the composition comprise particles having particle size greater than 25 microns. Also disclosed herein are methods of making and using the same.
Biodegradable fire resistant foam
The instant invention is a fire protectant composition comprising water, a surfactant, a water-soluble polymer, casein, and a calcium salt. The compositions can be applied to materials such as wood in advance of a fire, and after application, the compositions are capable of retaining their fire protectant capacities for days, weeks or even months. This fire protectant composition is also biodegradable and nontoxic. It is also easily removed from the combustible material by a water wash once the fire danger is passes. If burned, the composition forms a skin which can be peeled off or removed by some other method such as pressure water spray or mechanical brushing.

Multifunctional coating films that can be applied in liquid form
Multifunctional coating films that can be applied in liquid form are provided for compressing, sealing, covering and preserving surfaces. The films include a composition of polysaccharide materials and/or homo- or heteroglycan water-soluble polysaccharide derivatives, polyol spacers, and crosslinkers with carbonyl or carboxylic function(s). As-applied, the composition is water-soluble and reactive, but after hardening it is capable of absorbing water or swelling, impermeable to water vapour, stable against water and UV and can be biologically degraded in a controlled manner. By reacting polysaccharide materials, polysaccharide derivatives and polyol spacers with cross linkers having carbonyl or carboxylic function(s), mechanically stable flexible films are obtained, which retain their mechanical properties up to a foreign material content of 80%. The films can swell in a controlled manner and can bind up to 75% water relative to their dry weight, corresponding to the degree of crosslinking and the spacer that is used.

Coating compositions
A coating composition includes pigments or a mixture of pigments, a surface active substance and a metal containing polymeric complex. The metal containing polymeric complex contains a metallic salt, a polymeric latex and polyvinyl alcohol (PVA), wherein the polyvinyl alcohol has a molecular weight ranging from about 10,000 to about 65,000.
