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.
