  • Patent number: 6013797
    Abstract: At least bis-imido 1,3,5-triazines and processes of preparing the same are disclosed. Also disclosed are prepolymers having at least bis-imido functionality and curable compositions comprising at least bis-imido 1,3,5-triazines or prepolymers thereof in combination with active hydrogen and/or epoxy functional materials. The at least bis-imido 1,3,5-triazines and prepolymers may be advantageously employed as crosslinking agents which crosslink by a ring opening reaction that eliminates the release of volatile organic compounds.
    Type: Grant

  • Patent number: 5925285
    Abstract: A novel crosslinker composition based on a combination of 1,3,5-tris-(2-carboxyethyl)isocyanurate and a dicarboxylic acid crosslinking agent is provided. Also provided is a curable epoxy composition employing, as the crosslinker component, a combination of 1,3,5-tris-(2-carboxyethyl)isocyanurate and a dicarboxylic acid crosslinking agent, which curable composition finds use, for example, in coating applications. When cured, these coatings provide hard, durable and resistant films of low gloss.

  • Patent number: 5817709
    Abstract: Sulfonimide cure catalysts are used with aminoplast crosslinking agents and resins capable of reacting with aminoplast crosslinking agents to prepare heat curable compositions capable of crosslinking to form coatings and articles. Liquid or solid curable compositions may be prepared. Solid sulfonimide catalysts used in combination with solid glycoluril type crosslinking agents are well suited for powder coating systems containing hydroxy- and carboxy-functional resins.

  • Patent number: 5672703
    Abstract: New classes of 1,3,5-triazine compounds and compositions containing the same are disclosed, which compounds are of the general formula ##STR1## wherein each of Y, Z and optionally X are independently selected from a group of the formula (II), (III) and/or (IV) ##STR2## These compounds and compositions are particularly suitable for use as crosslinking agents in curable compositions such as coatings, particularly in combination with active hydrogen groups-containing materials. The 1,3,5-triazine compounds of the present invention do not release formaldehyde as a volatile by-product during cure, and certain of these compounds may be used in curable compositions which may be cured at relatively low temperature. Processes for preparing such compounds, compositions containing the same, as well as additional uses thereof, are also disclosed.
