摘要:
A treatment for paper, containing (A) a fluorine-containing polymer comprising repeating units derived from a fluorine-containing monomer (a) represented by the general formula (I):
CH 2 =C(-X)-C(=O)-Y-(CH 2 ) m -Z-(CH 2 ) n -Rf (I)
wherein X is hydrogen, methyl, fluoro, chloro, CFX 1 X 2 (wherein X 1 and X 2 are each hydrogen, fluoro, or chloro), or the like; Y is -O- or -NH-; Z is -S-, -SO-, or -SO 2 -; Rf is fluoroalkyl having 1 to 6 carbon atoms; m is 1 to 10; and n is 0 to 10.
摘要:
Powder coating compositions having reduced volatility and improved processibility compared to conventional powder coatings consist essentially of a copolymer having pendant functionalities or pendant groups capable of reacting with a dicarboxylic acid such as the glycidyl groups of glycidyl acrylate or methacrylate copolymer and a cross-linking effective amount of a dicarboxylic acid. The reaction of the above pendant groups and the dicarboxylic acid cross-links or cures the powder coating after application to a substrate. The dicarboxylic acids according to the invention eliminate the need for a third component which is a flow control agent which improves the processibility of a two-component powder coating. The dicarboxylic acids according to the invention have a sublimation temperature great enough to decrease or prevent their vaporization during the curing of the powder coating and have a melting point low enough to impart improved flow properties to the powder coatings.
