Abstract:
The present invention relates to a polyamide resin composition having excellent weather resistance and coating adhesion property and more particularly, to the polyamide resin composition capable of direct painting without pretreatment of primer and maintaining excellent weather resistance for a long period of exposure outside by adding an appropriate amount of a weathering stabilizer and a coating adhesion improver.
Abstract:
PURPOSE: Provided is a polyamide resin composition excellent in weather-resistant stability and coating property, which contains a weather-resistant stabilizer and a coating adhesion improving agent, therefore, can coat directly without a primer treatment. CONSTITUTION: The polyamide resin composition comprises: 30-99pts.wt. of a polyamide resin obtained by polycondensing one or more than two kinds of epsilon-caprolactam, amino caproate, 7-amino heptanoic acid, alpha-piperidone, and etc. or polycondensing one or more than two kinds of diacids and diamines; 1-65pts.wt. of a reinforcing filler such as glass fiber, glass bead, glass flake, mica, talc, carbon fiber, and etc.; 0.1-5pts.wt. of the hindered amine-based weather-resistant stabilizer having a molecular weight of 3000-4000; 0.1-5pts.wt. of the coating adhesion improving agent selected from an antioxidant, a heat stabilizer, an antistatic agent, and a fire retardant agent containing phosphorus.

Abstract:
PURPOSE: A micro pellet type thermoplastic polyurethane composition for powder slush molding process and a manufacturing method thereof are provided to enhance mechanical property, light-proof, heat resistance, anti-hydrolysis property, and releasability. CONSTITUTION: A micro pellet type thermoplastic polyurethane composition for powder slush molding process comprises 5-10 weight% of ester-based polyol, 5-10 weight% of ether based polyol, 30-70 weight% of polycarbonate diol, 10-50 weight% of isocyanate, 5-30 weight% of chain extender, and 0.1-5 weight% of light-resistant stabilizer. The ester based polyol is more than one kind which is selected from polycaprolactone polyol, butylene adipate, ethylene adipate, and diethylene diadipate. The ether based polyol is polypropylene glycol, polytetramethylene ether glycol, or a mixture thereof.
Abstract:
PURPOSE: A TPO sheet composition is provided to ensure excellent bondability with an aqueous coating agent such as an aqueous primer and a surface treating agent and to enable the manufacture of automobile interiors with excellent properties through female vacuum molding. CONSTITUTION: A TPO sheet composition comprises 35~45 weight% of partially crosslinked thermoplastic olefin resin, 5~15 weight% of non-crosslinked thermoplastic olefin resin, 10~20 weight% of polypropylene resin, 10~20 weight% of ethylene octene rubber, 10~20 weight% of linear low-density polyethylene resin and 5~10 weight% of inorganic filler. The partially crosslinked thermoplastic olefin resin has a hardness of Shore A 65.
Abstract:
PURPOSE: A modifier for a reactive hot melt adhesive, and the reactive hot melt adhesive including thereof are provided to secure the initial adhesive force and the coherence strength between non-polar materials, and to prevent the generation of volatile organic compounds. CONSTITUTION: A modifier for a reactive hot melt adhesive contains a multi-block copolymer. The multi-block copolymer is obtained by polymerizing a polymer initiator having a hydrophilic segment formed by condense-polymerizing a hydrophilic polymer and 4,4`-azobis(4-cyanopentanoic acid), layered silicate, a vinyl monomer, and a chain transfer agent.
