Open Coat vs. Closed Coat

Open Coat vs. Closed Coat

When discussing or reading about coated abrasives, the terms "open coat" and "closed coat" may often come up.

Grit Grading System

Grit Grading System

KONAFLEX's coated abrasive products, except Alumina Zirconia and Ceramic Aluminum Oxide, are graded by grit size using the FEPA (Federation of European Producers of Abrasives) or P-grade scale. Some competitive products are graded according to the CAMI (Coated Abrasives Manufacturers Institute) scale. P-graded products are easily identified by a "P" preceding the grit size designation on the back of the material. The chart on this page compares both the scales and the relative sizes of abrasives in inches and microns.

All About Grains

All About Grains

AO is formed by combining bauxite and other materials, and firing them in an electric furnace. The resultant mass is crushed, and the pieces sifted through successively finer screens to assign a grit size (CAMI grading). When crushed, the resulting pieces are naturally pyramidal. Due to the shape and the strength of the materials used in its making, AO is a very durable grain. The grain is worn down during use, sanding finer the longer it's used.
