2, the coating film appearance is smooth, good luster, high transparency;
3, super group of uniform electrophoresis ability, easy to adjust
tank liquid;
4, the tank liquid stability is good, no coating flow hanging, no
special technology, easy coating management;
5, the coating of high efficiency, economic saving, no waste
water discharge, green environmental protection;
6. The coating film has high hardness, strong corrosion
7. resistance and superior performance;
7, can be transparent bright electrophoretic coating, add
matching colorful paste, can also be a variety of color
electrophoretic coating, elegant color natural.

5. Packaging and storage
(1) Packaging :25L or 200L plastic bucket;
(2) Storage: When storing this product, it should be kept
ventilated and dry, prevented from direct sunlight, away from
heat source and fire source, and also prevented from freezing
under low temperature in winter. The product can be stored for
12 months at 0 ~ 30℃ from the date of production. Products
beyond the storage period should be tested to determine
whether to continue to use.
Ⅲ.Application field, market prospect and industrial production conditions of project products
This product is mainly used for electrophoretic coating of
aluminum alloy building profiles. It is one of the coatings that
must be used in aluminum profile factory. Each ton of aluminum
needs about 15 ~ 18 kg of coating, and the aluminum
processing plant that produces 1000 tons of aluminum profiles
consumes about 16 tons of electrophoretic coating every
month.
The market demand is large and the application prospect is
broad.
The production equipment and process of special
electrophoretic coating for aluminum profiles are relatively
simple, mainly the reaction kettle and peripheral equipment,
simple packaging equipment, equipment investment is less, the
production process is easy to master.
Ⅳ.Analysis of technical and economic benefits of
Industrialization，Project environmental assessment and analysis
The gross profit of electrophoretic coating for aluminum
profiles is 8500-9000 yuan per ton. It is easy to buy raw
materials in the market, and mass production forms a scale
with good economic benefits. The raw materials of color
electrophoretic coating for aluminum profiles are non-toxic
common chemical raw materials, and there is no waste water,
waste gas and waste residue discharge in the production
process, which will not pollute the environment.
Ⅴ.Mode of technology transfer cooperation
One-time technology transfer, provide a full set of technical
formula, production process, equipment list and raw material
procurement manufacturers, construction specifications, etc.
Can study in my company, on-site training, learn so far.
Engineers can also be sent to provide on-site technical services
to guide the production of qualified products. At the same time,
we can provide a complete set of solutions such as plant and
equipment selection, how to promote the market, raw material
procurement, how to make color plate, how to reduce
production cost and improve production efficiency, so that you
can put into production in the shortest time and make profits
quickly. You can change the formula as needed. And a
professional engineer consultant, can long-term tracking
technical guidance, remove worries.
Detailed project feasibility analysis report on request.
Product technology for large-scale production of mature
technology, technology transfer fee call to discuss.
