5. JA202# Polyurethane Resin 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
