Product Details
YD-151K Epoxy Curing Agent
PROFILE
YD-151K is a fatty amine modified epoxy hardener with light color
and very good initial hardness and strength build-up time. It is
recommended to be applied in stone dry-hanging adhesive pure white
formula, epoxy joints and other fields.
ADVANTAGES
Hardness and strength build up quickly, cost-effective.
- Light color, plus powder after placing 4 months without yellowing,
the surface of the colloid does not turn yellow.
Low odor.
APPLICATIONS
STORAGE
It should be sealed in its original packaging and stored in a dry
place at a temperature range of 0-40°C (the temperature must not
fall below 0°C). It should not be placed in direct sunlight.

Company Profile
Shenzhen Feiyang Protech Corp., Ltd. specializes in researching and
producing polyaspartic polyurea resin and other new chemical
products. We are recognized as a "National Special New Key Little
Giant" and a "State-level High-tech Enterprise", with more than 50
polyaspartic polyurea invention patents. We also participated in
the preparation of 13 industry standards for polyaspartic polyurea
materials as a leading company in this field, ranking No.1 in the
Chinese market.
In the coating industry, polyaspartic polyurea is used in
construction machinery, automobile, containers, fan blades, marine
heavy corrosion protection, and high-end industrial and commercial
floor coatings. In the adhesive field, it is mainly used in
sealants, stone adhesives, electronic adhesives, film circuit
packaging adhesives, and other high-end applications. In the
waterproofing materials sector, it is primarily used in
hydroelectric dams, water parks, building waterproofing repair
materials, and other areas. In the structural materials field, it
is applied to curling tracks, artificial ice skating rinks, and
other structural materials.
Polyaspartic polyurea is considered a high-end new material in the
strategy of manufacturing power. We have broken the foreign
technology monopoly and filled the domestic market gap. Due to its
comprehensive characteristics of "Environmental protection, Energy
saving, and Long durability", polyaspartic polyurea can contribute
to the realization of genuine carbon neutrality in the coatings,
adhesives, and materials industries.

Since 2012, Feiyang polyaspartic ester resin has been supplied
overseas. It has been widely used to replace Bayer's current
polyaspartic system in many coating companies and has been applied
in anti-corrosion and waterproofing by international coating
companies.
