Abstract
Novel alkylcarbamylmethyl aminotriazines self-cure and also function as crosslinkers for compounds containing active hydrogen groups. When the active hydrogen-containing compounds are hydroxylated polymers, coatings are provided with exceptional resistance to detergent and salt-spray exposure and improved abrasion resistance. The novel aminotriazines also can be combined with fillers as binders which when cured provide shaped articles of manufacture, such as insulation and foundry core molds.
Claims8
