The auto industry is hyper-competitive, pushing their
factories for maximum productivity while pushing their suppliers for lower
prices. SolEpoxy rose to this challenge with two of the world’s most productive
and affordable motor armature coating powders.
DK7-20H is a new Class H motor insulation epoxy with the most
cost-effective Class H formulation on the market today. In side-by-side
testing, DK7-20H outperformed the two leading Class H coating powders:
- 12% more armatures per hour when run
side-by-side on electrostatic fluid bed coating lines.
- A Thermal Index of 186°C, higher than
the competition and comfortably above 180°C for Class H.
- Floor life greater than 3 months at 23°C;
Storage life greater than 18 months at 10°C.
- The most affordable Class H coating powder on
the market today.
But most DC motors do not require Class H insulation. Most
micro-motors operate well below 180°C and only require Class F
insulation. Many manufacturers use Class H powder on all of their motors – whether
needed or not, simply to avoid downtime needed to thoroughly clean and change
powders in their powder coating equipment.
SolEpoxy offers a solution. DK7-20H is color-matched and
chemically compatible with our most economical Class F insulation powder:
DK15EG-05. And, DK15EG-05 is also solvent and gasohol resistant. It’s been used
on in-tank fuel pumps for years!
We’re inviting our most cost-sensitive customers to try
DK7-20H and DK15EG-05 in a single
coating line. Utilize DK15EG-05 for motors requiring gasohol resistance and lower
operating temperature because this is the most affordable Class F powder on the
market today. Then vacuum out DK15EG-05 and load DK7-20H for those motors which
require Class H insulation.
- DK7-20H and DK15EG-05 are color-matched and chemically
compatible so change-over is easy.
- Both DK7-20H and DK15EG-05 ran faster than the
competition in our side-by-side production test on electrostatic motor coating
lines. These were the two most productive powders!
- Both powders have 3-months of floor life at 23°C,
- Both powders feature SolEpoxy’s proprietary
catalyst technology which enables their useable life to be extended with
refrigeration. At 10°C they’ll keep for a year and half!
We formulated these powders to make manufacturing and
And, both DK7-20H and DK15EG-05 are very affordable –
especially when compared to the current Class H competition. By using both powders
for different motors but on the same coating line, fractional horsepower motor
manufacturers can minimize their cost of coating powder and maximize the
productivity of their coating lines. Contact SolEpoxy for more information, for
samples and for pricing.
