摘要:
The present invention relates to fast drying waterborne printing inks and to method of using such inks in high speed printing processes, such rotogravure and flexographic printing processes. The printing ink includes, for example, a blend of a latex binder and a polyfunctional amine. The pH of the ink is raised by adding a sufficient amount of base, to a point where essentially all of the polyfunctional amine in the blend is in a deprotonated state.
摘要:
The composition having wet state clarity includes an aqueous latex binder combination of polymer particles with a diameter of less than 80 nanometers and a thickener. When glitter flakes are dispersed in these novel compositions in their wet state, they glitter more than conventional glitter compositions. Thus, they are more appealing to a consumer or an artist than conventional glitter compositions that tend to be cloudy or dull in their wet state.
摘要:
A waterborne coating composition containing an aqueous dispersion of a polymerr bearing at least two active methylene groups and being substantially free from hydroxyl, primary amino, and secondary amino groups, and an aqueous dispersion of a polyisocyanate bearing at least two isocyanate groups is provided. Also provided is a method of improving the chemical resistance of a coating and a substrate coated with the waterborne coating composition.
摘要:
A method for reducing the amount of microfoam in a spray-applied clear waterborne thermoset composition is provided. The clear composition comprises an emulsion-polymerized addition polymer or a multi-staged emulsion-polymerized addition polymer with an average particle diameter greater than 120 nanometers and bearing at least two first reactive groups, and a reactive modifier bearing at least two reactive groups. The clear composition is spray-applied to a substrate and cured. Also provided are substrates bearing such spray-applied clear compositions and the emulsion-polymerized addition polymer.
摘要:
An aqueous polymer dispersion containing a predominant amount of first polymer particles and a smaller amount of second polymer particles is provided. The first polymer particles have a glass transition temperature in the range of from -20 °C to 25 °C. The second polymer particles include multiethylenically unsaturated monomer as polymerized units, and have a glass transition temperature of less than 0 °C. The aqueous polymer dispersion is useful for providing dry coatings having improved dirt pickup resistance and an acceptable level of scrub resistance. Also provided is an aqueous coating composition including the aqueous polymer dispersion and a method for preparing a dry coating from the aqueous coating composition.
