摘要:
Disclosed are a adhesive composition and a method of surface-treating a molded article using the same. In particular, the adhesive composition may be eco-friendly because smell and VOC generation from the organic solvent are reduced by adding a water-dilutable polyurethane resin having a hydroxyl group to a waterborne polyurethane resin, thereby improving properties such as elastic recoverability and scratch resistance while satisfying conventional properties.

摘要:
The present invention relates to a non-coating thermoplastic resin composition, a method for manufacturing a molded article by using the same, and a molded article manufactured by the same. More specifically, the present invention is characterized by providing the thermoplastic resin composition which contains polycarbonate, polysiloxane-polycarbonate copolymer, polyester, master-batched carbon black, and additives in specific contents and the molded article, which has excellent chemical resistance, mechanical properties, light resistance, hydrolysis resistance, and low glossiness, manufactured by using the same.
摘要:
Disclosed are an uncoating metallic thermoplastic resin composition invention including metallic particles at an appropriate ratio and a molded article including the same. The molded article may maintain the mechanical properties such as impact strength and fluidity at an excellent level as well as improving the appearance characteristics such as luminance characteristics (high luminance) and metallic texture. The uncoating metallic thermoplastic resin composition and the molded article thereof may be usefully applied to the molded products in fields where the characteristics of the appearance quality are importantly required, for example, cell phone housing, TV housing, computer monitor housing, automobile bumper, wheel housing, panel button portion, interior and exterior lighting lamp housings, and the like.
摘要:
Disclosed is a coating material for a coating layer of an injection mold, the coating material including 100 parts by weight of a resin composition and about 30 to 40 parts by weight of a curing agent. The resin composition includes an amount of about 40 to 50 wt % of a first acrylic resin, an amount of about 5 to 15 wt % of a second acrylic resin having a weight average molecular weight less than a weight average molecular weight of the first acrylic resin, an amount of about 10 to 15 wt % of a carbon component, an amount of about 0.5 to 2 wt % of a matting agent, an amount of about 0.1 to 0.3 wt % of a catalyst and an amount of about 20 to 35 wt % of a solvent, all the wt % are based on the total weight of the resin composition.
摘要:
Disclosed is a polypropylene resin composition for an uncoated crash pad. The composition may include an amount of about 50 to 80 wt % of a polypropylene resin having a Polydispersity Index (PI) of about 4.5 to 6.5, a weight average molecular weight of about 200,000 to 350,000 g/mol, and an isotactic peptide fraction of about 96% or greater as measured by a C13-NMR method, an amount of about 1 to 30 wt % of rubber having a melt index of about 1 to 6 g/10 min (230° C., 2.16 Kg), an amount of about 11 to 30 wt % of an inorganic filler composed of a mixture of an amount of about 10 to 20 wt % of talc and an amount of about 1 to 10 wt % of whisker, and an amount of about 1 to 5 wt % of an anti-scratch agent, all the wt % are based on the total weight of the polypropylene resin composition.
摘要:
Disclosed are a resin composition and a molded article using the same. The resin composition may be obtained by mixing a thermoplastic vulcanizate and a polyethylene resin with a thermoplastic olefin resin, a polypropylene resin, an inorganic filler and a thermoplastic rubber, and in particular, the thermoplastic vulcanizate and the polyethylene resin may be obtained from biologically obtainable materials (biomass). Thus, the resin composition may be environmentally-friendly because it does not emit offensive odor of harmful compounds due to decreased generation of carbon dioxide and volatile organic compounds unlike petroleum-based materials. Further, superior mechanical properties such as elongation, hardness, strength, etc. that cannot be achieved only with conventional biodegradable resin may be ensured, and, at the same time, processability and moldability may be improved.

摘要:
A polypropylene resin composition may include an amount of 40 to 60 wt % of a polypropylene resin, an amount of 1 to 10 wt % of a polyethylene resin, an amount of 10 to 20 wt % of an olefin elastomer, and an amount of 1 to 20 wt % of a reinforcing material wherein all the wt % are based on the total weight of the polypropylene resin composition. Accordingly, a high gloss may be obtained without a coating process and moldability of the polypropylene resin may be obtained. Further provided is a molded article of an interior material or an exterior material of a vehicle manufactured by using the polypropylene resin composition.
