JA201# Polyurethane Resin

1. Description
JA201# polyurethane resin is a polymer material developed material， room temperature curing， two-component, with low viscosity, small odor, soft, transparent glue. For it’s good advantages of Wear resistance, yellowing resistance, UV resistance and never hardens,it is widely used for outdoor application.

2 Application
1)Used in aviation, railways, construction, sports and other aspects;
2)Surface varnish for wooden furniture and metal;
3)Insulation for storage tanks, pipes, cold storage, beer, fermentation tanks, cold preservation barrels
4)Waterproof for building insulation
5)Used for prefabricated polyurethane sheet
6)For the products making of plastic products, wear-resistant synthetic rubber, synthetic fibers, hard and soft foam products
7) For adhesives and coatings;such as for :all types of wood, chemical equipment, telecommunications equipment and instrumentation and surface finishing of various means of transport, toys, handicrafts, hand model, gifts, etc.

＊Low viscosity, and good leveling

5. Operation instructions
1. Operated under the conditions of ventilation environment.
2. Prepare the tools , and make sure it is clean ,dry . Un-oil ,and not contact with any chemical Solvent
3. Weigh part A and part B exactly ( multi-component part A will leads to the bottom of the bubble, multi-component B may cause surface sticky).
4. Carefully stir in the same direction to avoid a large number of bubbles, you need patience and stir until completely transparent.
5. Vacuum Pumping : Vacuum pumping by vacuum machine

6. Warm tips :
1 The humidity should less than 60% if using by hand , you would better to use a dehumidifier
  2 You would better to use metal or plastic tools instead of wooden articles .
  3 You should make sure your products is very dry , and can not use inks containing glycerol.
  4 This product (especially B glue) can’t contact with skin , otherwise please wash with plenty of water and soap
  5 Resin will be cured with High temperature and cured very fast
  6 Far away from children to prevent eating.
