  • Patent number: 11951650
    Abstract: A protectant and sealant solution and method of use thereof, configured to protect wood from premature decay when disposed in contact with the earth. The solution is composed of processed hemp oil which is mixed with bio-diesel and other oils to form the protectant solution. The wood is then impregnated with the solution via pressure treatment within a retort cylinder. The solution is configured to protect utility poles and other wooden construction members which are known for prolonged contact with soil. The solution is designed as a safe replacement for pentachlorophenol solutions which have been found to be harmful to the soil and water table.

  • Patent number: 8021585
    Abstract: A method is described for preparing liquid concentrates of additives for incorporation in polymers, particularly polymers prepared in solution or slurry phase polymerization media. Additive concentrates according to the invention are characterized by a finer dispersion than would result from the direct addition of particulate or granular additives to the same liquid solvent.

  • Patent number: 7052630
    Abstract: In this application is disclosed a resin additive composition which can by produced by precipitating a calix(n+m+l)arene represented by the following general formula (2) and in a dissolved state together with or at the same time at least one functional ingredient selected from the group consisting of various water-soluble or hydrophilic resin flam-retardants, resin thermal stabilizers and resin curing agents, and in a dissolved or suspended state. This resin additive composition has a good affinity for organic polymers such as polyolefin and the like, which allows the functional ingredient(s) to be dispersed homogeneously in the resin. Therefore are provided high-performance resin compositions comprising various functional ingredient(s).
