Recommendation: Boron Nitride Lubricoat®

Boron Nitride LUBRICOAT®  is an excellent choice to prevent dross/skull from welding to the press head.  LUBRICOAT® provides protection and release for 40 to 50 cycles before re-coating is needed.  In field trials, LUBRICOAT® provided longer lifetime than any other coating available.  Please refer to LUBRICOAT® product discussion page for added details.

Coating Maintenance Guide

Application to press heads is somewhat different that the standard application methods as described in the PAINTING INSTRUCTION GUIDE. The procedure for press heads is as follows:

1. Clean the press heads of any dross, dirt, ...etc.

2. Preheat the press head (gas burners) to about 400 - 600 F.

3. Air-spray onto the hot press head a coating of LUBRICOAT® between 5 to 8 mils. This is thicker than normal!

4. For maintenance, when dross/skull begins to adhere, any skull and loose coating is removed (usually by wire brushing), and fresh coating is applied as above.

The m ost commonly reported coating defect is flaking due to inadequate cleaning of the press head prior to coating.
