Cutting and Grinding Fluids CG 4250

Cutting and Grinding Fluids CG 4250 is a light oil film rust preventative designed to protect parts stored indoors for up to 1 year. The light oil coating is not easily disturbed during shipping and handling and possesses residual protective characteristics even if part of the compound is wiped or rubbed from the metal surface. Due to surface-active ingredients, the coating will creep over uneven or unclean surfaces to insure a continuous film. Thus it can be used on porous metals and parts with deep crevices insuring 100% coverage.

Features: Corrosion Resistant, Non Corrosive

Compatible Substrates & Surfaces: Brass, Metal, Zinc

Product Note

CG 4250 should be applied to parts that are relatively dry, as the water displacing characteristics are limited with this product. CG 4250 should also be avoided if small parts are to be coated and stacked in boxes for storage, as the oily film is thick enough to collect on the surface of small parts and may cause issues during assembly. CG 4250 is to be used straight, do not cut back further with solvent or mix with water.
