Applications & Uses+
CYCAT 4040 catalyst is a very versatile catalyst material especially formulated for consistency of strength for use in various solvent soluble and water-based thermosetting vehicles. It is especially recommended where a strong acid catalyst is desired to accelerate the cure of highly alkylated melamine-formaldehyde crosslinked systems and to reduce the curing temperature of urea resin systems.
While catalyst usage will be dependent upon resins, and cure time and temperature, generally 0.5 % catalyst solution, based on total resin solids, will be a satisfactory starting point. For low temperature cure schedules from 1 to 2.5 % or higher, levels of CYCAT 4040 catalyst are often required. The minimum level of catalyst to achieve the desired film properties should be used, however, since excessively high levels of catalyst can reduce the water resistance of a finish.
CYCAT 4040 catalyst is an alcohol soluble catalyst. It is insoluble in aliphatic and aromatic hydrocarbons and partially soluble in glycol ethers, esters and ketone solvents. In order to prevent recrystallization of the acid, a sufficiently high level of alcohol should be present in the total solvent system of a formulation. recrystallized acid can cause a reduction in cure response and may create local areas of high acidity which could cause the formation of gel structures. From 5 to 15 % of the total solvent should be primary alcohol; however, in high solids systems where the total solvents in the formulation may be only 20 % by volume or less, higher levels of alcohols might be necessary to maintain catalyst solubility.
Safety & Health+
CYCAT 4040 catalyst is a flammable liquid and vapor that can cause eye burns and skin irritation.
