ADVANTAGES Improved: Solvent-free adhesion Wide compatibility corrosion resistance Stability overbake gloss retention overbake frilling resistance flow and leveling APPLICATION AREAS Water-reducible finishes Metal decorating finishes High solids coatings Automotive primers Coil coating enamels Appliance primers CYMEL 1170 resin is a member of a new class of high performance amino crosslinking agents, with improved performance characteristics over existing melamine and benzoguanamine crosslinking agents. CYMEL 1170 resin is reactive with hydroxyl, carboxyl and amide groups and is compatible with most water and organo-solvent borne acrylic, alkyd, epoxy, epoxy ester, polyester and vinyl polymers. Especially outstanding is the improvement in adhesion obtained with films crosslinked with CYMEL 1170 resin. This improved adhesion provides increased corrosion resistance and flexibility. The better adhesion is not lost after postforming of parts and exposure of the stressed coating to humidity, steam, dry heat or the weather. This feature makes CYMEL 1170 resin a good candidate for coil or metal decorating enamels and primers. CYMEL 1170 resin requires strong acid catalysis for optimum cure response. A level of about 0.5-1.0% CYCAT ® 4040 catalyst (based on the total binder) is required for optimum cure with normal bake schedule. CYMEL 1170 resin gives excellent stability even in highly catalyzed formulations. The presence of weakly basic reacting compounds such as melamine or urea resins or basic pigments can reduce the cure response of CYMEL 1170 resln. This resin has a very low tendency to self-condense. Approximate levels of CYMEL 1170 resin can be calculated using the equivalent weight of 150-230. For optimum results, ladder studies should be made. SOLUBILITY CYMEL 1170 resin is soluble in most commonly used alcohols, esters, ketones, glycol ethers and hydrocarbon solvents (both aliphatic and aromatic). It has limited solubility in ethylene glycol, diethylene glycol and water. COMPATIBILITY This resin is compatible with most acrylic, alkyd, polyester, epoxy, vinyl and cellulose resins. It is partially compatible with amine-neutralized anionic acrylic and polyester resins used in water reducible coatings. Generally, up to 30% CYMEL 1170 resin (based on total binder) has been found compatible with these systems.
