摘要:
The waterborne coating composition herein is useful for promoting adhesion of paint to a component such as a plastic automobile part or accessory. The waterborne coating composition is particularly useful for promoting adhesion of paint to a thermoplastic polyolefin surface. The waterborne coating composition is prepared from a mixture comprising at least one chlorinated polyolefin resin and at least one urethane acrylic hybrid resin. The waterborne coating composition provides not only good adhesion of a paint to a thermoplastic polyolefin surface, but also provides good appearance. The waterborne coating composition is also compatible with a wide variety of paint systems and can be rapidly dried under ambient conditions.
摘要:
The invention relates to a plastic from a group comprising polyethylene (PE), polypropylene (PP), polypropylene/ethylene-propylene-diene-rubber (PP/EPDM) or mixtures thereof, wherein the plastic is coated by a primer comprising a halogenized polyolefin, and the primer is coated by an elastic paint cured by polymerization using a radical reaction, wherein the plastic is an expanded plastic, wherein the paint prevents the penetration of moisture.

A composite article (20; 120) includes a substrate (22; 122) and a protective coating (32; 132) on at least a portion of the substrate. The protective coating includes reinforcement particles (34) dispersed within an elastomeric matrix (36) that is modified with a silicon-containing modifier selected from polysilsesquioxane, polyhedral oligomeric silicate and polyhedral oligomeric silsesquioxane (POSS).
摘要:
A chlorinated propylene-based polymer of the present invention having a weight average molecular weight (Mw) as measured by gel permeation chromatography (GPC) of 5,000 to 100,000 and a chlorine content of 0.1 to 70 % by mass has the following properties: (1) it has a high solubility in a non-aromatic solvent having a low environmental burden even when it has a low degree of chlorination, and (2) it can be inhibited from suffering a decrease in the properties inherent to polypropylenes, such as durability, mechanical properties, appearance and hydrophobicity, by regulating its degree of chlorination at a low value.

A binder resin composition is provided which retains satisfactory low-temperature flowability and coating film performances and has a lower cost. A binder resin solution composition including: (a) a resin obtained by mixing a chlorinated polyolefin (I) obtained by chlorinating to a chlorine content of 10 to 40% by weight an isotactic polypropylene polymer produced in the presence of a metallocene catalyst, the isotactic polypropylene polymer having a molecular weight distribution of 3 or lower and a melting point as measured with a differential scanning calorimeter of 110 to 140°C; with a carboxyl-containing chlorinated polyolefin (II) obtained by chlorinating to a chlorine content of 10 to 40% by weight a carboxyl-containing polyolefin obtained by grafting 1 to 10% by weight at least one unsaturated carboxylic acid monomer selected from a carboxylic acid and a carboxylic acid anhydride onto an isotactic polypropylene polymer produced with a titanium catalyst in a weight ratio (I)/(II) of from 5/95 to 50/50; and (b) an organic solvent, in which the composition has a solid concentration of 10 to 50% by weight.
摘要:
A high-solid anticorrosive coating composition which comprises a main ingredient (A) comprising an epoxy resin (a1) and a hardener ingredient (B) comprising an alicyclic amine hardener (b1) and/or a Mannich type hardener (b2), the ingredient (A) and/or the ingredient (B) containing at least either of an additive (a2) selected among epoxidized reactive diluents and modified epoxy resins and a coating film modifier (ab) selected among petroleum resins, xylene resins, coumarone resins, terpene phenol resins, and vinyl chloride copolymers. The high-solid anticorrosive coating composition especially of the rapidly curable type is characterized by containing a high-boiling organic solvent having a boiling point exceeding 150°C and containing substantially no organic solvent having a boiling point of 150°C or lower.
摘要:
The invention relates to an adhesive additive for a water lacquer, comprising at least one binding agent and/or at least one pigment and/or filling material and at least one halogenated polyolefin (HPO), water, up to 25 wt. % solvent and, optionally, normal additives for water lacquer. The inventive adhesive additive makes it possible to apply lacquers directly onto plastic substrates without the need for an undercoat.
