摘要： PURPOSE:To provide a trimming material for vehicles, which does not cause deterioration even when exposed to the atmosphere over a long period of time, consisting of a polyolefin resin compsn. contg. a specified organonickel compd. weathering and light-resistant agent. CONSTITUTION:0.05-2wt% [2,2'-thiobis (4-t-octyl phenolate)]-n-butylaminenickel of the formula is blended with a polypropylene resin such as a polypropylene/ ethylene copolymer having an ethylene content of 5-20%. The resulting resin compsn. is processed into a trimming material in a conventional manner by subjecting it to stages of molding, degreasing (washing with trichloroethane vapor), masking, primer coating, baking, topcoating and baking, said weathering and light-resistant agent remains in the resin compsn. while scarcely dissolving out of the compsn. during the above degreasing stage, so that a member having excellent resistance to light and weather can be obtd.

摘要： PURPOSE:To make a plastic bumper so as not to expand or contract by a temperature variation, by installing plural projections in a keep plate, which is applied to the surface of a plastic facia locked to a bumper stay and situated in position between the facia and a clamping bolt. CONSTITUTION:When a bolt 5A is clamped tight, a projection 8 is bitten in a resin layer of a facia 1 in consequence. When the facia tries to extend in longitudinal direction by a temperature variation, movements in both directions of the facia 1 of its own are prevented due to a relationship between a screw part of the bolt 5A and a setting hole 6A and bitingness in the projection 8. And, the facia 1 is expanded or contracted quite as much as that of an armature 3 and a keep plate 4. That is to say, expansion or contraction of the facia 1 by the temperature variation is absorbed as heat distortion among, the armature 3, the keep plate 4 and the facia 1. With this constitution, an expansion value of the facia 1 is little as a whole whereby its end part will not interfere with a front fender panel and in no case being projected from that.

摘要： PURPOSE:To enable high quality painting free from a painting flaw such as a pinhole or a crater, by molding the base material of a resin product and subsequently applying heat treatment to the molded one at temp. equal to or more than the baking temp. of a paint. CONSTITUTION:The base material of a resin product is molded by using a reinforced plastic material such as unsaturated polyester, an epoxy resin or PBT. In painting, the base material is washed at first and subjected to heat treatment at temp. equal to or more than the baking temp. of a paint in a heating oven and the gas in the contraction voids or cavities in the base material is expanded to be expelled to the outside and the closed voids or cavities are released. In this state, painting by an under coat and a top coat and baking/ drying are successively applied to the surface of the base material but, in both cases, baking/drying is performed at tamp. lower than heat treatment temp. to obtain a high quality resin product free from a painting flaw.
