4030A/4030B polyurethane resin (Domes Resin)
First, the features:
4030A/4030B two-component room temperature curing series polyurethane resin system, does not contain any solvents and volatiles, cures crystal clear, crystal clear and brilliant protective coating.After curing the coating thickness is typically in the 1.5-2mm formed three-dimensional effect can be widely used in various signs, nameplates and ornaments.4030A / B cured with a very excellent weathering properties and resistance to UV, long-term use in the outdoors, can fully meet the demanding requirements of the automotive industry for materials in the outdoor sun 4030A / B can ensure that more than three years remain yellow.
Second, the composition:
4030A multi-isocyanate component, 4030B for the polyol component, depending on customer requirements can be cured with different hardness, different curing time, viscosity of different products, and machinery to meet the hand-drip infusion ofrequirements.

Fourth, the use of technology:
4030A / B sub-type and mechanical manual drip drip-type, hand-drip-type can be used for a long time, slow curing, mechanical infusion model can be used a short time, curing fast.
1, manual infusion
a, control the temperature at 15-25 ℃, relative humidity <70%, 4030A and 4030B in this condition for 24 hours after use, 4030A may be crystallized at low temperature behavior, heat recovery to the clear liquid before use.
b, the level of home plate on the surface, and fixed with adhesive.
c, clean plate surface buildup of dirt and oil.
d, the right weighing 4030A 4030B, by weight ratio 100:55 full uniform mixing.
e, mixture of vacuum removal of air bubbles.
f, hand signs or devices on the surface of infusion.
g, with a needle struck the surface covered with glue to glue set, and pick in addition to residual air bubbles.
h, set infusion of good signs in the temperature 15-25 ℃, relative humidity <70% of the dust-free environment.
i, 24 hours that complete cure can be closed container.
2, mechanical infusion process
⑴ standing 4030A 4030B packaging at room temperature 15-25 ℃ relative humidity <70% dust-free environment,> 96 hours to remove the folder during transport into the bubble.
⑵ were put into the feed pump and seal fixed, for 24 hours.
⑶ home plate on the horizontal surface, and fixed with adhesive.
⑷ clean plate surface of the buildup of dirt and oil.
⑸ washed with dichloromethane and cast head pipe mixer
⑹ play materials, excluding pipelines, mixers and air bubbles in the casting head
⑺ drip on plate surface
⑻ struck with a needle covered with glue is the glue surface, and pick in addition to residual air bubbles.
⑼ good sign for home infusion temperature of 15-25 ℃, relative humidity <70% of the dust-free environment.
⑽ 24 hours that complete cure can be closed container.

7, Packing specifications:
Packaging 20KG, 50kg, 200kg metal drums.
Eight, storage, transportation and precautions:
1 such products as non-dangerous goods, transport as common chemicals.
2 in 15% -25 ℃ relative humidity <70% condition, dark enclosed storage, product storage period see drums.
3 manual drip, press the correct ratio of weighing, the full mix, weighing more than 100g, you can use shortened.
* Note: The above performance data for the product in 70% humidity, temperature 25 ℃, the typical test data for customers reference, and can not guarantee that in a specific environment can be achieved when all the data.Please use the customer, subject to the measured data.
