Room Temperature Curing Polyurethane materials is Bi-component. A is polyol component, and B is MDI-terminated prepolymers.
Room Temperature Curing Polyurethane resin has excellent processing properties, cured under room temperature, short demould time, and the color can be changed by adding pigment. The final polyurethane products are transparent which enjoy good abrasion resistance, water resistance, good resilience. The hardness is in the 30 to 93 shore A hardness range.

Operation by manual
1. Take certain A component to make reserve.
2. Calculate B component to make reserve.
3. Pour B component to A component and stir evenly.
4. Cast the mixture of step 3 to the mould.
5. Open the mould when the product is hard.
6. Post cure 16 hours at 100℃.
Note: The mixture in the step 3 can be vacuumized to get rid of bubble.
Operation by casting machine
1. Put some A component into A tank, vacuumize to make reserve.
2. Put some B component into B tank, vacuumize to make reserve.
3. Cast the two materials according the ratio to the mould.
4. Open the mould when the product is hard.
5. Post cure 16 hours at 100℃.
Safety
