K-CORR NF-410 is an ashless, easy to handle, extreme pressure additive and an outstanding yellow metal protecting additive. K-CORR NF-410 protects yellow metals and its alloys by scavenging the sulfur released by highly active sulfur carriers. To obtain maximum yellow metal protecting results, it is beneficial to use a combination of K-CORR NF-410 and K-CORR NF-200, a barrier film yellow metal deactivator.

K-CORR NF-410 specifically exhibits excellent EP properties in polyglycol based lubricants and greases. K-CORR NF-410 also provides outstanding FZG (ASTM D 5128) performance when used in mineral oils or synthetic base stocks.
K-CORR NF-410 protects oils from the catalytic pro-oxidant effects of dissolved copper ions. Even better protection can be obtained by using K-CORR NF-410 in combination with K-CORR NF-200.

Depending upon the base oil type and other additives used, the recommended treat level of K-CORR NF-410 is 0.04% to 0.50% by weight. When using K-CORR NF-410 as an EP additive, the recommended treat level is 1.0% to 3.0% by weight.
