Catalyst for the 2 Part Epoxy Ink
We supply catalyst for virtually any epoxy ink. Inquire if you do not find what you are looking for. Most of these catalyst are available from 1oz to 4oz containers.
Mixing Ink With Catalyst: Add 1 part catalyst to 6 parts ink by weight.
Catalyst: The amount of catalyst should only be based on the weight of the ink and not include
the weight of any other additives. Catalyzed ink requires an “induction period” or time lag of
about 30 to 45 minutes. Catalyzed ink has a pot life of 6 to 8 hours.
HYSOL / ENTHONE CATALYST DESCRIPTION
Catalyst / Description Cure / Average Pot Life* (hours)
20/A Basic air cure catalyst. Cures at room temperature in 5-7 days.
Tack free after 1-2 hours.
May also be heat cured. *R.T. or Heat 2 hours
B-3 Basic heat cure only catalyst. Higher cure temperatures decrease cure time.
Heat 4 hours
5 Long pot life. Excellent adhesion properties. Special mix
ratios are required for this heat cure only catalyst (refer to
Color Numbers and Mix Ratios Section). Heat Cure. Average Pot Life (hours) 24 Max.
B-13/28 Accelerated air cure catalyst. Cures at room temperature in 3 days. Shorter pot life.
*R.T. or Heat 1 hour
45 Discontinued
77 Adhesion promoting catalyst. Cures at room temperature in 5-7 days.
Provides similar characteristics as Catalyst 45.
Maximum adhesion is achieved by heat cure @ 65.6-93.3 oC (150-200oF)*R.T. or
Heat 1 Hour * @ 21°C (70°F)
9 Basic heat cure only catalyst with good anti-yellowing resistance.
(Recommended for use with 50-110RX). Heat Cure. Average Pot Life (hours) 7.
* Note: When using Catalyst #5 discard ink after 24 hours.
ADE Catalyst for the ADE Epoxy Inks
MIXING INSTRUCTIONS Measure
ink and catalyst at the proper mix ratio (refer to Section 2.0). 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 homogenous mix
of resin and catalyst and allows any entrapped air to escape from the
mixture. The average pot life begins after the induction period
APPLICATION
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.
OPTIONAL ADDITIONS Additions of thinner or flow agents
should always follow the induction period. If the induction period is
not observed, the thinner or flow agent may interfere with the
catalyzation process and could effect the final cured properties.
