  • Patent number: 5998035
    Abstract: A coating method is disclosed, which comprises coating a base coating paint on a substrate, coating thereon a clear coating paint of a curing system different from that of the base coating paint in a wet-on-wet state, and then baking the resultant coatings, wherein a curing catalyst for curing the clear coating paint is incorporated into the base coating paint and wherein the curing catalyst has a boiling point of 150.degree. C. or higher under 760 mmHg. The base coating paint comprising such a curing catalyst is also disclosed.

  • Patent number: 5962588
    Abstract: The present invention provides a curable resin composition incorporating an oligomer containing blocked hydroxyl group, an epoxy-group containing compound, hydrolytic silyl-group containing compound, and a dissociation catalyst and/or curing catalyst, each possessing a specific molecular weight; a paint which uses this resin composition as a binder; and a coat-finishing method which coat-finishes any desired material using the aforementioned resin composition and paint. According to the present invention, it is possible to reduce viscosity, and consequently increase the coat non-volatile content and hence improve acid resistance, abrasion resistance, and the like. In addition, according to the present invention, it is possible to obtain a curable resin composition, paint using this curable resin composition, and coat-finishing method for this paint in which the aforementioned resin and paint have an extremely high utility and possess a high solid content wherein air bubbles and drip-runs are not generated.

  • Patent number: 5945483
    Abstract: There are disclosed a high solids content resin composition excellent in solubility in an organic solvent, comprising an acrylic oligomer having a blocked hydroxyl group, a curing agent having a reactivity with a hydroxyl group and a dissociation or curing catalyst, and a high solids content type paint using the resin composition. There are also disclosed a coating process and a baking process comprising coating and baking the resin composition or the paint while rotating a material to be coated at an appropriate speed. The resin composition and the paint of the present invention have substantially no sagging and solvent popping. Further, the thus obtained paint film have improved smoothness, solvent resistance, weather resistance and resistance to scratching.

  • Patent number: 4523484
    Abstract: A dilution pipetter comprising a diluent sucking probe, a sample probe for sucking and discharging a liquid sample, a diluent discharging probe disposed adjacent to the sample probe, a plunger pump of small plunger diameter selectively communicating with the diluent sucking probe or the sample probe by a first switching means, and a plunger pump of large plunger diameter selectively communicated with the diluent sucking probe, the sample probe or the diluent discharging probe by a second switching means. The dilution pipetter is useful as, e.g., an element of a clinical chemistry analyzer which is used to conduct numbers of reactions for small quantities of a liquid sample such as serum of the warm blooded animal including humans.
