摘要:
The present invention relates to an epoxy-based coating resin composition which facilitates the transcription of the printed letters or photographs developed by sublimation dyes on printing paper to the surface of potteries, glasses, marbles, metals or woods only by thermal treatment and more particularly, to the epoxy-based coating resin composition with 1) long-tern storage stability due to the use of a mixture of diethanolamine and triethanolamine as a hardening accelerator, 2) uniform thickness after coated, 3) less air bubbles after dried, 4) good depth in printing, and 5) a releasing property which promotes easier separation of printing paper from its coated surface after transfer-printed.

This invention relates to a process for manufacturing a highly efficient antislipping agent based on acrylic latexes containing small amount of solid content, wherein said acrylic latexes are composed of two different acrylic latexes containing small amount of solid content; one being flexible with a low glass transition temperature (referred to as ‘Tg’ hereafter) when dried and the other being hard with a relatively high Tg when dried, followed by blending through neutralization using aqueous ammonia. Thus, the latexes are well blended and their physical properties like homogeneity, tacky property, flexibility and hardness can be easily controlled.

This invention relates to polymer sealant microencapsulated by polyurethane reaction and its binder solution, particularly employing threaded mechanical fasteners such as bolt-nuts, screws, pipe joints and threaded nails, etc. The microcapsules are prepared by interfacial polyurethane reaction of triisocyanate with poly-functional alcohol under the aqueous oil-droplets solution containing vinyl monomers, oligomers, redox initiators and organic solvents together as core materials of the microcapsules. The binder solution of the microcapsules is prepared by dissolving chloroprene, polyester acrylate, urethane acrylate, carboxyl- or hydroxy-modified vinylchloride-vinylacetate copolymer, coinitiators and fillers in a mixture of tetrachloroethylene and toluene.
