CYMEL-659
CYMEL® 659 resin is a partially n-butylated benzoguanamine resin supplied in n-butanol. Like other benzoguanamine resins, CYMEL® 659 resin imparts excellent adhesion and chemical resistance to the coating, but without the need for an external catalyst in the formulation. Because of the limited light resistance properties of benzoguanamine resins, CYMEL® 659 is not suitable for exterior applications.
