All Du-Mor Coater Blades are precision wet honed so that NO heat is induced into raw material, allowing distortion free finishing and the Ultimate in Accuracy.

Blue Polished Coater Blade Steel
Alloy Coater Blade manufactured from the finest quality 1095 carbon coater blade steel in the world.  Industry Standard Coater Blade made of the finest 1095 carbon steel with extra accurate straightness and blade angle for repeatability from blade to blade and order to order.  Directional camber inspection is included with all Du-Mor Coater Blades.  Blade angles are held to +/-1/2 of 1 degree accuracy.  Hardness is between 52-54 Rockwell C Scale.

"Extra Special Coated" Coater Blade
Du-Mor Blade proprietary coating applied to the coater blade material, giving the blade a thin protective skin which enhances application of coating color to sheet by lowering the coefficient of friction by over 30-%.  Also, eliminating corrosion along the heel of the blade and coating buildup gives operators a maintenance free blade where blade consistency and performance are critical.

Stainless Steel Coater Blade: 716 (420 mod)
Manufactured from a special 420 mod Stainless Steel designed and engineered for coater blade application.  This material has the same basic specs as the blue carbon but a slightly higher hardness and improved wear characteristics.  Corrosion resistant.

Ultra Glide Coater Blade Series:
All the properties of Extra Special Coated except for increased wear.  This blade can be used in areas where a slightly longer wearing blade is needed over blue polished steel coater blades.  ie:  Blue Polished Steel wears 4-5 hours; Ultra Glide 8-10 hours - usually double when coating formulas do not contain high percentages of calcium clay or Titanium Oxide.  Ultra Glide is a middle performance wear product.

Friction Guard Alpha Coater Blade Steel
Industry’s first coater blade that uses our long wear encapsulation principal.  This process encapsulates the entire blade and bevel with our patented coating.  This product is extremely positive where coating formulations burn the heel of the standard coater blade which in turn creates defects in the sheet.  This product greatly enhances blade life and in most cases eliminated blade wear related coating defects.  This product is a direct drop in for blue polished steel coater blades.

All Friction Guard and Ultra Glide Coater Blades are manufactured using the Du-Mor Patent Pending Process and are available in stages to serve the needs of all coating situations. 

Friction Guard Superia Coater Blade Series:
(Du-Mor Friction Guard Ceramic Technology)

Friction Guard Superia I – This is the true work horse of ceramic blade technology. Outwears and outperforms all competitors.
· Aluminum Oxide plus Zirconium Oxide
· Higher Hardness than II, therefore giving Longer Life

Friction Guard Superia II – Not quite the wear of Superia I but contains enhanced profiles and greater sheet gloss, excellent performance for a ceramic coater blade.
· Aluminum Oxide and greater amounts of Zirconium Oxide
· Lower Hardness than I, reduces life over Superia I
· Better Profile
· Improved Glossiness

Friction Guard Superia I + or II + - Special Extra Procedure that can be added to Superia I or II.
· Reduces any Scratches
· Reduces any Streaks
· Further Extends Life
· Better Smoothness of Coated Surfaces – Furthermore Improving Paper
