Special Features and Benefits
BYK-Catalyst 450 accelerates the cross-linking of amino resins with hydroxyl group-containing resins. Low reactive melamine formaldehyde HMMM (hexamethoxymethylmelamine) resins, in particular, need an accelerator to lower the baking temperature or to shorten the baking time. The increase in viscosity of the product is significantly lower during storage compared to that of pure p-toluene sulfonic acid, which extends shelf life by 1.5 to 3 times. With this additive, the baking temperature can be decreased by 10-20 °C in comparison with other blocked p-TSA catalysts (such as those containing morpholine or aminomethyl propanol blocking agents).
Recommended Use
The additive is recommended for automotive refinish coatings, industrial coatings and overprint varnishes.
Recommended Levels
1.5-6% additive (as supplied) based upon solid resin, depending on the reactivity of the base resin and the content of melamine resin and pigment. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions : Add to the let-down or the thinner. The solvent mixture must contain 10-20% polar solvents such as
alcohols, glycol ethers or esters.
