Meets Mil Spec: CID A-A-56032D Types I, II & III Formerly: MIL-I-43553b
Measure ink and catalyst at the proper mix ratio. Both the ink and catalyst should be weighed accurately. Excessive and insufficient amounts of catalyst are detrimental to cured ink film properties. Mix thoroughly without introducing excessive amounts of air. Avoid the use of paper or wax coated cups. Stir from bottom of the container
OBSERVE INDUCTION PERIOD
All catalysts: 30 minutes
Catalysts 45 and 5: 60 minutes
Allow ink/catalyst mixture to stand for at least 30 minutes prior to application. This provides an induction period ensuring a homogeneous mix of resin and catalyst and allows any entrapped air to escape from the mixture. The average pot life begins after the induction period
50-000 Series inks may be applied by screen printing, spraying, brushing and roller printing. To ensure optimum adhesion, it is imperative that the surface to be printed is clean and free of any residues or particulates.
BLACK and WHITE stocked / all other colors are not as popular and are considered a special order
