General Information
L-207A Novacite® is the "star" of the Line. Normally the product will disperse to a 7 Hegman Grind. All Particles are individually platey with few clusters. 98% of the particles will fall between one and ten microns. L-207A as fine as it is still has the uniqueness of low binder demand with superior flow properties.
