- Solvent component: Ethyl Acetate
- Improve heat resistance of adhesive
- Enhance water resistance of adhesive
APPLICATION & CHARACTERISTIC
- WPU-70-62I is a water-emulsifiable polyisocyanate.
- Cross-linking action enhances heat resistance performance, water resistance, resistance toward plasticizers and organic solvents for cement.
- WPU-70-62I serves as a cross-linking agent for aqueous PU dispersions.
PHYSICAL PROPERTY
| Appearance | Nearly colorless or Light-yellowish liquid |
| Viscosity | < 100 cps (VT-04/25℃) |
| Main Component | polyisocyanate |
| Solid Content | 50 ± 2 % |
| NCO% | 10 ± 1 % |
| Solvent components | Ethyl Acetate |
| Storage temperature | 5 - 40℃ |
PROCESSING METHOD
- Add 3-5% WPU-70-62I by weight to the Water Based PU adhesives and mix by agitator at 300-500 RPM for 8-10 mins, use up the mixed cement within its pot life (2 hours)
- Add 1% more WPU-70-62I during raining days and high humid days.
- When mixed with PU dispersions, it will generate CO2, so don’t seal mixed cement.
NOTICE
- Over exposure to water / moisture will cause the hardener turn viscous and cure itself.
- WPU-70-62I should be kept in tightly sealed containers at temperature between 5-40℃. Below this storage temperature WPU-70-62I may partly crystallize.
- When the product is transferred from one container to another, must prevent its over exposure to water, including moisture in the air .
- After pouring out from the original containers, containers of WPU-70-62I should be made of glass or aluminum .
- Close the cap of container tightly when not use, should be sealed well to prevent it reacting with moisture.
PACKING
1kg/aluminum can.
