When used on high-speed continuous coating lines, coil coatings must withstand rigorous processing such as bending and stamping without cracking, while also exhibiting excellent weather resistance. For coil coatings, TAIGA Additives’ acid catalysts release active acids during the curing process, precisely catalyzing the cross-linking reaction between amino resins and polyesters/polyurethanes. This ensures that the coating achieves the required hardness and solvent resistance within an extremely short curing time, while preventing pre-reaction in the can. Leveling agents reduce the surface tension of the coating, ensuring uniform film spread and a smooth, orange-peel-free finish during high-speed application.
