摘要:
A method of cationic electrodeposition, electrocoated articles and novel electrocoating compositions are disclosed. The compositions comprise a cationic resin containing blocked isocyanate functionality and are capable of being electrodeposited over rough steel and producing extremely smooth films upon curing.
摘要:
A compressible substrate coated at least in part with a waterborne coating composition comprising at least one base neutralized active hydrogen containing film-forming resin and a water dispersible carbodiimide crosslinker capable of reacting with the film-forming resin to form a crosslinked film is disclosed. An article of manufacture having at least two different flexible substrates coated at least in part with such a coating is also disclosed.
摘要:
The present invention is directed to a method for producing bicyclic guanidines comprising heating a reaction mixture comprising cyclic urea and a dehydrating agent to a temperature ≧90° C.
摘要:
Disclosed are terminal-modified difunctional sulfur-containing polymers that are the reaction products of a sulfur-containing diol, an aldehyde or a ketone, and a compound containing a functional group. Compositions comprising the terminal-modified difunctional sulfur-containing polymers useful as sealants are also disclosed.
摘要:
A composite photonic crystal comprising an inverse opal structure defining an ordered array of voids with a filler composition received within the voids. A property of the filler composition changes in response to a stimulus, such as a temperature change, thereby changing the band gap of radiation that is reflected by the composite photonic crystal.
摘要:
The present invention is directed to a method for preparing a cyclic guanidine comprising reacting (i) a guanidinium, (ii) a polyamine, and (iii) a weak acid. The present invention is also directed to a coating composition comprising the cyclic guanidine.
摘要:
The present invention is directed to copolymers, which are polymerization products of: (i) a monomer having alpha-olefinic functionality; (ii) a monomer different from (i) having active hydrogen functionality; and (iii) a monomer different from (ii) having acrylic functionality. The molar ratio of the monomer (i) having alpha-olefinic functionality to the monomer (iii) having acrylic functionality is less than 1:1, and the conversion of the monomer (i) having alpha-olefinic functionality during polymerization is greater than 90%. When monomers having methacrylic functionality are used to prepare the copolymer, the molar ratio of the monomer (iii) having acrylic functionality to the monomers having methacrylic functionality is greater than 2:1. Also disclosed are curable film-forming compositions comprising the copolymers.
摘要:
The present invention is directed to a non-gelled, curable composition including at least one compound having a plurality of imide functional groups. The compound in particular contains a reaction product of at least one secondary monoamine and at least one maleimide, and is suitable for use in coatings and castings.
