摘要:
There is provided a polyarylene sulfide dispersion coated with a cationic group-containing organic polymer compound and having high dispersion stability and excellent adhesion or adhesiveness to any one of substrates of plastic, metals, glass, and the like even at a high polyarylene sulfide resin concentration. The object is solved by providing a polyarylene sulfide dispersion including polyarylene sulfide particles, which are coated with a cationic group-containing organic polymer compound by a base precipitation method and thus exhibit high stability even at a high concentration, and also providing powder particles (fine particles) produced from the dispersion.

Compositions, such as aerospace sealant, coating, and/or potting compositions are disclosed. The compositions include a polythioether and, in at least some cases, can be sprayable and fuel resistant even when substantially free of volatile organic compounds.
摘要:
The present invention relates to a resin composition, in particular suitable for printing, a kit comprising the components of the resin composition, a printing method utilizing the resin composition, a polymer obtained by the printing method, an article comprising or formed from the polymer, and uses thereof. The resin composition may be in particular suitable for printing and comprises at least one compound C1 having (i) at least one terminal alkyne functional group, and (ii) at least one functional group selected from the group consisting of a carbonate, a carbamate, and an ether; and at least one compound C2 having at least two thiol functional groups.
摘要:
The present invention is directed to anti-corrosion coatings. It is particularly directed to coatings comprising electroconductive polymers polymerized in the presence of one or more film forming polymers. These coatings can be used with metal substrates such as cold-rolled steel and other metals to inhibit corrosion.

An inverter surge-resistant insulated wire, having an enamel baked layer, an adhesive layer, and an extrusion-coated resin layer, around the outer periphery of a conductor, wherein the sum of the thickness of the enamel baked layer, the extrusion-coated resin layer, and the adhesive layer is 60 µm or more, wherein the thickness of the enamel baked layer is 50 µm or less, and wherein the extrusion-coated resin layer is formed from a polyphenylene sulfide resin composition, which contains a polyphenylene sulfide polymer having a melt viscosity at 300°C of 100 Pa·s or more, 2 to 8 mass% of a thermoplastic elastomer, and an antioxidant, and which has a tensile modulus of elasticity at 25°C of 2,500 MPa or more, and a tensile modulus of elasticity at 250°C of 10 MPa or more.
摘要:
The present invention comprises a process for coating a substrate with a coating comprising a fluoropolymer. The process comprises the sequential steps of: a. Preparing a solid mixture comprising one or more fluoropolymers and one or more thermoplastic polymers thermally stable at temperatures in excess of 4000 C; b. Melt blending and extruding the solid mixture at a temperature of from about 2500 C to about 4000 C to achieve homogeneity; c. Subjecting the extrudate to mechanical means to obtain a powder of up to about 100 microns average particle size; d. Applying the powder onto the substrate; and e. Heating the substrate to a temperature sufficient to cause the powder to become sufficiently fluid to coat the substrate.
