FORMULATION FOR A FIBROUS NON-WOVEN FACING MATERIAL

Abstract:

The present invention provides a formulation for a fibrous non-woven facing material, wherein the formulation comprises a binder, a filler, and an extender. The extender has an median particle size, d.sub.50, which is equal to or less than 3.5 .mu.m, and a non-spherical morphology. The filler has an median particle size, d.sub.50, which is equal to or less than 3.0 .mu.m and wherein the filler has a d.sub.10 equal to or less than 1.0 .mu.m and a d.sub.90 equal to or less than 6.0 .mu.m. The formulation comprises less than 13 wt % titanium dioxide on a dry solids basis. Also provided is a fibrous non-woven facing material comprising the formulation, a process for preparing the fibrous non-woven facing material and a fibrous non-woven facing material obtained by said process.
