Cymel 5011 Benzoguanamine resin Cytec Amino Resins Coatings >> Solventborne Architectural / Decorative Can Coating n-Butanol Insoluble in water Soluble in xylene BENZOGUANAMINE RESINS Benzoguanamine resins are similar to melamine-based resins in that they, too, are triazine based, but in this instance, the triazine has a benzene group substitution. Therefore, they are less functional than melamine-based resins, and are not UV resistant. Benzoguanamine resins are noted for their enhanced film flexibility, or toughness, and for their chemical resistance. They are typically used in primers, container coatings, and appliance finishes. Usually, highly alkylated, monomeric benzoguanamine resins result in higher film flexibility than that which can be achieved with other types of resins, but they also require the addition of a strong acid catalyst for adequate cure at temperatures greater than 125°C. Their practical equivalent weights are slightly higher than the practical weights of their melamine counterparts and range from 160-220. The less alkylated polymeric resins only require the acidity of the other components in the formulation to cure adequately at greater than 125°C, but they have higher VOCs in a solvent-based formulation. Their practical equivalent weights are also slightly higher than those of their melamine counter-parts and range from 200-260 on a solids basis. The use of a blocking amine and the addition of a stabilizing alcohol to the formulation should enhance formulation stability. n-Butylated, polymeric general purpose resin. n-Butylated, polymeric general purpose benzoguanamine resin. Used in primers, container coatings, and appliance finishes. Offers enhanced film flexibility, or toughness, and chemical resistance.
