The Dynoadd P-range of monodisperse, spherical particles provide especially fine and uniformly textured films. The particles have an extremely narrow particle size distribution, ensuring that every particle gives the desired effect, resulting in lower addition rates than competing technologies. They can give some improved scratch resistance and impart a permanent slip improvement. The Dynoadd P-range have low refractive index, which gives the opportunity of producing textured or matt clear coats without imparting haze to the coating. The products can be combined both with other particle size Dynoadd particles, or matting agents to give the required texture, gloss and structure.
