  • Patent number: 6384101
    Abstract: A surface treatment composition of the present invention comprises (A) urethaneacrylate oligomer, (B) acrylate based monomer, (C) photoinitiator, (E) silicon additive, and (E) silica matting agent. The present invention provides a surface treatment composition in which imparts abrasion and scratch resistance to the surface of a soft type urethaneacrylate oligomer decorative floor covering, and ameliorates the problem of low stain resistance caused a low density of elaborate crosslinks by using a small amount of single functional group monomer. The present invention also provides a surface treatment composition in which employs only hard type urethaneacrylate without single functional group monomer so that cross linking density is increased and the effects of oxygen that prohibits the surface cuing are minimized, resulting in improved stain resistance.

  • Patent number: 6368994
    Abstract: A method for rapid polymerization, curing or a combination thereof of a polymerizable or curable composition to yield polymers and composites based on these polymers through the utilization of short wavelength microwave energy is described. The inventive method is generally applicable to the chemical transformation of any organic material that can be processed by heating. This invention also relates to specially prepared particulate polymerization curing materials which, when dispersed and irradiated in a polymerizable or curable composition, will effect rapid polymerization, curing or a combination of polymerization and curing of that composition without exceeding the decomposition temperature of the polymerizable or curable composition when the composition is exposed to microwave radiation. The polymerization agent may also be encapsulated by a material which coats the polymerization agent to prevent its premature release into the polymerizable or curable composition.
