Additives for Coil Coatings
The high line speeds of industrial band coating operations and the subsequent extreme deformation of the coated sheets demand coatings with very good color stability. They must also be free of foam, provide excellent leveling, adhere well and have surface characteristics such as smoothness, scratch and abrasion resistance, and also enhanced ease of cleaning. With BYK additives, these properties can be achieved in all coil coating application areas.
