LASER MARKING PRODUCT
1.0 Product description
RD-6012 is a laser marking material for metals. It is similar to LMM-6000 but is applied to the substrate by screen printing. It can be used on a variety of bare metal substrates including stainless steel, brass, aluminum, titanium, tin, nickel, and many more. RD-6012 will not work on metals with a lacquered coating.

3.0 Product Preparation
Insure that the product has been well mixed prior to use. Some settling may occur during long storage. Paste temperature should be equivalent to your printing room temperature prior to measuring viscosity or application.
4.0 Viscosity Test Method
Cerdec product viscosity is measured by a Brookfield™ RVT DVIII Viscometer using a #27 spindle, 100 rpm at 24.0 ºC.
5.0 Storage Recommendations
Product must be stored in cool and dry conditions. The storage temperatures should not be below 5ºC and not exceed 35ºC. Settling could occur if stored for long periods of time. Before use, products must be stirred thoroughly. Partly used containers must be tightly sealed after use. If stored as recommended, a minimum shelf life of six months after the production date is guaranteed.
