Ⅰcharacteristics
Our domes resin
4030A/4030B is a two-component, room temperature curing
product. It doesn’t contain solvents or any other volatile
materials. It produces a clear, attractive and protective
coating. The thickness is about 1.5~2 mm with
three-dimensional effect. Our products can be widely used in
producing various kinds of label, nameplates as well as
decorations. What’s more, because of its excellent
resistance to weathering and ultraviolet light, our resin
satisfies the strict requirements of auto industry.
The outdoor use
resin is guaranteed against yellowing when exposed to
sunlight for a period of three years at least.
Ⅱcomponents
4030A is
polyisocyanate, 4030B is polyalcohol, no matter using by
machine or by hand, the products can meets customer’s
requests of different hardness, curing time and viscosity.

working process
Here the
techinics can be divides into two kinds: manual process
andmachine process, the former one cures longer than the
later one.
1、manual
process
a、
Keep 4030A/B in the room with the temperature of
15~25℃
and the humidity < 70% for 24 hours before use. 4030A may
rime in low temperature, please warm up to 30~40
℃
till it turns to clear liquid
b、Put
label on the worktable and fix with adhesive tape.
c、Clean
the dust and dirt on
the label
d、Weigh
4030A/B correctly, the weight ratio is 100: 55. Stir them
adequately.
e、Vacuum
the mixture to de-bubble
f、Inject
on the surface of
label
g、make
the liquid all around the surface with needle, and break the
bubble
h、Put
the
label in the clean room of 15-25℃
and humidity <70% for 24 hours
2、machine
process
⑴
Keep 4030A/B in the room with the
temperature of 15~25℃
and the humidity < 70% for 96 hours before use to eliminate
bubbles
⑵
Put the pump respectively into 4030A and
4030B, sealed and fixed, leave them still.
⑶
Put
label on the worktable and fixed with adhesive tape.
⑷
Clean the dust and dirt on
the label
⑸
wash blender, pipe and injecting pinhead
with dichloromethane
⑹
inject 4030A/B into the machine in
advance to eliminate bubbles from blender, pipe and
injecting pinhead
⑺
inject on the surface of
label
⑻
make the liquid all around the surface
with needle, and break the bubble
⑼
Put the
label in the clean room of 15-25℃
and humidity <70% for 24 hours

cautions
1.
Not belong to dangerous goods, can be delivered as
common ones
2.
Store it at the cool and dark place(15-25℃
humidity<70%)
Weigh up 4030A/B
correctly and stir them adequately. Pot life may shorten if
the amount is more than 100g.
Note: the
data above3 are typical tested at relative humidity of 70%
and a temperature of 25℃.
They are just for reference. We cannot guarantee all the
listed data will be reached under specific test conditions.
When applying the product, the customers should use data
obtained through their own testing.
