PL268
Alumina Core Paint

PL268
Alumina Core Paint

PL268 is used on designated areas where metal does not flow properly. PL268 is used for pre-forming ceramics for the casting investment industry. To prevent ‘canalling’ defects on DS (Directionally stable metal ‘crystal’) castings using preformed cores made with a pure thin alumina coating applied by brush. A pure aluminium poly-hydroxy nitrate binder (mentioned in Russian literature as early as 1960’s) in which is suspended very finely fused 5 micron alumina and other additives.

Used with PL 268 Aid for help in spray application specified by Rolls Royce in helping production of parts.

This material contains less than 1 part per million lead, 0.5 parts per million bismuth, 1 part per million silver, 10 parts per million tin, 20 parts per million zinc, 10 parts per million antimony and less than 900 parts per million iron. In addition, there is no magnesium, calcium or silica.

Used by Rolls Royce and Lake Erie Design on preformed ceramic cores

Used at temperatures up to 1,350°C (2,462°F)
