摘要:
There is provided a resin composition for forming a self-lubricating liner which has low friction coefficient, high durability, high load capacity, high heat resistance and high oil resistance, as well as which can be subjected to a size adjustment through grinding or cutting after the curing.
摘要:
Resin compositions for powdery coatings which contain the components (A), (B) and (C) as specified below: (A) a carboxyl-containing resin having a number-average molecular weight of 1,000 to 20,000, an acid value of 5 to 200 and a glass transition temperature of 30 to 120 °C; (B) a poly-β-methylglycidyl compound carrying at least two structures represented by formula (1) per molecule; and (C) a steric-hindered amine as a heat yellowing inhibitor.
摘要:
A matte powder coating composition including a first carboxyl- functional polyester resin, a second carboxyl-functional polyester resin, and an epoxide-functional crosslinking agent, where the difference in acid values between the first and second carboxyl-functional polyester resins is from about 200 to about 350 mg KOH/g.
摘要:
To provide the thermosetting powder coating composition which comprises a fluorine-containing copolymer having crosslinkable functional group and a curing agent, in which the fluorine-containing copolymer has a fluoroolefin unit, has a fluorine content of not less than 10 % by weight and is not dissolved in tetrahydrofuran substantially. A coating line can be shared with other powder coating composition because even when the composition mixes to other powder coating composition, it causes no coating defects, and yet a coated article having a coating film excellent in physical properties can be provided.
摘要:
A thermosetting powder coating composition which comprises a powder of a composite resin comprising a vinylidene fluoride polymer having cross-linkable functional groups and a methyl methacrylate polymer and having a melt flow rate as measured at 130 °C under a 2.1 kg load of 1 to 1,000 g/10 min. The coating composition has the following advantages. The production thereof is easy because pulverization can be conducted at room temperature as well as at lower temperatures. The composite resin used has excellent compatibility with various hardeners. The composition gives a coating film having excellent properties.
