A one-pack coating composition is disclosed. The composition comprises (A) an oligomer or polymer containing an acid anhydride group, a blocked hydroxyl group and an epoxy group as indispensable functional groups in the same or different molecules, (B) a heat-potential curing catalyst which comprises a complex of an organometallic compound and an electron-donating compound or an onium salt and which exhibits its activity upon heating, (C) an ultraviolet absorber comprising a triazine or oxalic anilide, and (D) a hindered amine light stabilizer having a piperidine ring of the following structure: wherein R represents R1—CO—, a C2 to C20 alkyl group or R1—O— (R1 being a C2 to C20 alkyl group), and R2, R3, R4 and R5 independently from each other represent a C1 to C3 alkyl group, or a phenolic antioxidant. A method for coating using this coating composition is also disclosed.
摘要:
A thermosetting composition which gives a cured product having excellent weatherability, chemical and physical properties, in particular acid resistance and abrasion resistance, at a relatively low temperature, which has superior storage stability, and which can be used as a one component coating material; a coating composition utilizing this thermosetting composition; a method of coating; and a coated article are provided. The thermosetting composition contains a resin having at least one functional group selected from the group consisting of a blocked hydroxyl group, blocked carboxylic acid, and an epoxy group. The thermosetting composition has a blocked hydroxyl group, blocked carboxylic acid, and an epoxy group.

A lubrication apparatus for a four-stroke engine (1) is provided that prevents lubrication failure from occurring around the crankshaft and reliably prevents oil from remaining in a valve operating chamber (30). The lubrication apparatus for the four-stroke engine (1) includes: an intake part (55) positioned below the level of an oil A in an oil reservoir (7) even if the oil reservoir (7) is tilted and the level of the oil A changes; an oil feeding passageway (54) that sucks up the oil A from the intake part (55) and supplies the oil A to the crank chamber (5a); and an direct passageway (47) that allows communication between a valve operating chamber (30) and a crank chamber (5a) when a negative pressure is created in the crank chamber (5a). Open end parts (47a, 54a) of the oil feeding passageway (54) and the direct passageway (47) which are open in the crank chamber (5a) are provided to open as the piston (13) moves from a position near the top dead center to the top dead center. It is possible to control the flow rate of oil supplied to the crank chamber (5a) via the oil supply passageway (54) by means of a flow rate control passageway (67) that allows communication between a supply passageway (51) to supply oil mist from the oil reservoir (7) to the valve operating chamber (30) and the oil feeding passageway (54).
