1.Benzoin is
also called 2-Hydroxy-1.2-Diphenylethanone.
Whose chemical structure is : 
It can be applied to chemical industry, pharmaceutical products etc.
With rapid development of powder coatings, it is extended to this new
field to overcome the defects of pinlldes etc., which is caused by powder
coating raw material bonzoin is an ideal additive in powder coatings production.

Benzoin is widely applied in coatings and plastic, printing and electrical
industry, it is the best choice of high & midgrade photosensitive
material.
3. Luster-enhancing Agent
AC911 (bright resin)
Luster-enhancing agent AC911 is developed from monopolymer of acrylic
acid. It can improve the luster and surface hardness of powder coatings.
Moreover, it is provided with resistance to pollution.
4. Transparent Resin Coating
for Steel Measuring Tape:
It is developed from modified acrylic resin, provided with properties
of transparency and clarity, brilliance, good gloss retention, weatherability,
mechanical performance and resistance to chemicals. Moreover, its adhesive
power is quite strong to metals and it has the high-temperature solidifying
properties.
Uses: steel measuring tape, apparatus, domestics electrical appliances,
light industry products, etc..
5. Colored Resin Coating
for Steel Measuring Tape:
It is made from monopolymer and adjuvant of pigments. The coating of this
product is provided with good brilliance, luster, weatherability, mechanical
performance and resistance to chemicals. In particular, its adhesive power
is quite strong to metals and it has the high-temperature solidifying
properties.
Uses: steel measuring tape, apparatus, domestics electrical appliances,
etc..
