Aromatic isocyanates, especially MDI, have high reactivity. The flowable time of two-component raw materials after mixing is relatively short, which can not meet the process requirements of some products requiring long flowable time. The polymerization inhibitor NCAT-YC03 is developed to solve the above problems. It is especially suitable for black material (PAPI) + castor oil system.
Typical Properties：
Appearance | colorless transparent liquid |
Density (g/cm3, 25℃) | 1.073±0.02 |
Viscosity (mPa.s, 25℃) | 1-10 |
Odor | With slight special odor |
Solubility：Easily soluble in general polyurethane raw materials
Eco-friendly Characteristic:
It does not contain heavy metals, polycyclic aromatic hydrocarbons, o-benzene plasticizer and other environmentally restricted components, which complies with international general environmental protection regulations.
Features & Advantage:
Aromatic isocyanates, especially MDI, have high reactivity. The flowable time of two-component raw materials after mixing is relatively short, which can not meet the process requirements of some products requiring long flowable time. The polymerization inhibitor NCAT-YC03 is developed to solve the above problems. It is especially suitable for black material (PAPI) + castor oil system. It has the feactures and advantages as follows:
l Long pot life. It can effectively delay the reaction speed of polyurethane reaction and make the material have longer low viscosity operation time.
l The physical properties of materials are not reduced. NCAT-YC03 is a non reactive polymerization inhibitor, which does not participate in the growth reaction of polymer chain segments and does not affect the physical properties of materials.
l Good compatibility. Good compatibility with polyurethane raw materials, no phase separation and precipitation.
l Good environmental protection. No restricted substances, and no restrictions on environmental protection applications.
Applications：
It can be widely used in the process occasions of the polyurethane industry where it requires to extend the operation time. Particularly be recommended for the reaction system of PAPI + castor oil, such as floor coating, structural gel and aluminum honeycomb gel with good leveling performance.
User's Guide:
It is suitable for all kinds of single and two-component polyurethane. For single component, it is recommended to be added and stir evenly after the reaction and before discharging. For two components, it can be added to white material (polyol component) at any stage.
The general dosage is 0.05 ~ 0.3% of the weight of PU.
Be sure to seal and store immediately after use.
Handling & Storage:
Product should be stored in a cool, dry environment away from sunlight, excessive heat and rain.
Package: 25kg/200kg in HDPE drum
Shelf Life: The unopened shelf life is 18 months from the date of manufacture. After expiration, it can still be used if it passes the inspection.
