The present invention is directed to an adhesive composition, which comprises an epoxy resin, a coupling agent, filler, and an effective amount of an amine-curing agent or curative for said epoxy resin. Advantageously, tri-functional and / or tetrafunctional epoxy resins and / or acrylate monomers will be incorporated into the adhesive composition in order to reduce open time and enhance substrate adhesion. Advantageously, a mixture of amines will be used in the curative including aliphatic amines, which have low viscosities and efficiently wet the substrate for enhancing adhesion; polyamines, which can be used to manipulate open time and allow for improved ratio tolerance of the adhesive system; and amine-terminated rubbers (ATBN), which can improve impact resistance and the toughness of the cured adhesive. Preferred coupling agents are silanes.

A pharmaceutical or cosmetic carrier or composition for topical application characterized by rheological properties which render the carrier or composition semi-solid at rest and a liquid upon application of shear forces thereto. The composition or carrier are prepared by mixing 1-25 percent of a solidifying agent and 75-99 percent of a hydrophobic solvent, by weight, wherein at least one of them has therapeutic or cosmetic benefits, in the presence or absence of a biologically active substance.

The invention discloses water-based polyurethane composite adhesive for tanning and a preparation method and application of the composite adhesive, belongs to the technical field of water-based polyurethane composite adhesive preparation methods, and in particular relates to a method for preparing composite adhesive in the fields of artificial leather and synthetic leather. The method for preparing the water-based polyurethane composite adhesive for tanning is characterized by comprising the following steps of: reacting polyol polymer and isocyanate, adding chain extender, hydrophilic chain extender, cross linker, catalyst and solvent, reacting, cooling and emulsifying, to obtain emulsion; and mixing the emulsion, curing agent, wetting agent, tackifier, adsorbent and thickening agent uniformly, and thus obtaining the hot-melt adhesive for artificial leather adhesive layers. The water-based polyurethane composite adhesive for tanning is used for compounding polyvinyl chloride (PVC) / cloth for artificial leather of luggage and clothes. The prepared water-based polyurethane composite adhesive for tanning has high adhesive fastness and good water and solvent resistance, and can be applied to processes of knife coating, roll coating and the like of binding materials of middle layers of artificial leather and synthetic leather in the fields of textiles, leather processing and the like.

The invention is a kind of flexible ceram wearing and heat resisting heavy corrosion preventing paint, which is made up of epoxy resin and several kinds of ceram powder, rust-protection paint and firming agent, the weights of each ingredient are: (1) epoxy resin: 100; (2) additive: 50-120; (3) rust protection paint: 8-25; (4) ceram powder: 100-200; (5) compound solvent: 40-70; paint: firming agent=(35-50):1. The paint needn't base coat, it can be painted directly or brushed on the surface of metal under normal temperature, it has excellent wearing and corrosion prevention performance, impact resisting performance and flexibility, it can insulate acid, alkali, salt, saline water. The surface is smooth; it can be applied to oil pipe, oil pot, and chemical device, ship, wheel vane, pump, dust catcher, etc.

Powder coatings having good impact resistance and weatherability characteristics are produced with an isophthalic acid-based polyester and an isocyanate-based curing agent.

The invention relates to compound epoxy flooring coating adopting the mixture of epoxide resin and modified resin as a base material and further comprising organic solvent, dispersant, wetting agent, antifoaming agent, flatting agent, scratch resistance agent, pigment and stuffing as well as reactive diluent selected according to requirements. When in use, the coating is mixed and solidified withthe components of firming agent, accelerant, etc. By regulating the content of the components, the compound epoxy flooring coating of the invention can be used for manufacturing a solvent or solvent-free autolevelling epoxy floor. The compound epoxy flooring coating of the invention has favorable over-all properties, and not only has the characteristics of high mechanical strength, favorable anti-corrosion property, high adhesive force and good wear resistance property of the epoxide resin but also has the characteristics of good weather resistance, high decorative property and hardness and shock resistance of the modified resin; and the preparation method thereof is simple and practicable, is low-cost, and is suitable for mass preparation.

The invention discloses a high-temperature-resistant, anti-corrosion and thermal-insulation coating which comprises components in parts by weight as follows: 45-60 parts of film-forming resin, 20-30 parts of a pigment and filler, 15-30 parts of an aid and 25-30 parts of a solvent. The invention further designs a preparation technology of the high-temperature-resistant, anti-corrosion and thermal-insulation coating. The technology comprises steps as follows: firstly, mixing the film-forming resin with the pigment and the filler, sequentially adding an antifoaming agent, a leveling agent, a coupling agent, a crosslinking agent and a curing agent, and evenly stirring the mixture at the normal temperature to obtain the high-temperature-resistant, anti-corrosion and thermal-insulation coating. The coating has the advantages of environment-friendliness, low cost, high hardness, long service life, good heat resistance, good flexibility, good high-temperature resistance and the like.
