    • Disclosed is a stabilized phenolic resin melamine dispersion comprising a liquid alkaline resole resin composition and solid melamine crystal dispersed throughout the resin composition. The liquid alkaline resole resin composition comprises the reaction product of combining formaldehyde and phenol at a formaldehyde to phenol mole ratio of about 0.5:1 to about 3.5:1 in the presence of a basic catalyst. The melamine crystal to phenol mole ratio ranges from about 0.01:1 to about 1:1. Moreover, the composition has a free formaldehyde content of at most about 0.5 weight percent. A method for making this dispersion is also disclosed.
    • 公开了一种稳定的酚醛树脂三聚氰胺分散体,其包含分散在整个树脂组合物中的液体碱性树脂树脂组合物和固态三聚氰胺晶体。 液体碱性甲阶酚醛树脂组合物包含在碱性催化剂存在下,甲醛与苯酚的甲醛与苯酚摩尔比为约0.5:1至约3.5:1的反应产物。 三聚氰胺结晶与苯酚的摩尔比为约0.01:1至约1:1。 此外,组合物的游离甲醛含量至多为约0.5重量%。 还公开了制备该分散体的方法。
