One of the most important aspects of metal finishing is protection against rust.
Fortunately EPi has developed a rust preventative oil called E-Tec 515 that offers incredible protection against metal's age old enemy: rust. E-Tec 515 is a rust preventative oil concentrate formulated with emulsifiers. The advantage of emulsifiers, is that E-Tec 515 can be diluted in water at either 5% or 20% concentration. Film thickness, dry time, and coverage varies with the concentration in water. The corrosion resistance of the films will also vary with the concentration. E-Tec 515 produces approximately 50 hours salt spray resistance, and 96 to 150 hours resistance is obtained with 20% solutions.
