aromatic binders
AROBOND 300
AROBOND 300 is a modified aromatic diphenylmethane diisocyanate (MDI) developed for spray polyurea elastomer systems. It is formulated to provide balanced reactivity, suitable surface dry time, and strong overall physical performance in protective coating applications.
This Modified MDI prepolymer / aromatic isocyanate is designed for:
- Spray polyurea elastomers
- Protective coatings
- Waterproofing systems
- Polyurea hybrid applications
- Balanced reactivity
AROBOND 300 is pale yellow liquid at room temperature with a balanced reactivity for high-pressure spray applications. Our aromatic binder has a higher viscosity, and a slightly slower reaction profile allowing for a longer workable surface dry window.
Processing and Handling
AROBOND 300 is moisture sensitive and is important to keep containers tightly sealed and free from moisture. If crystallization occurs at low temperatures, heat the liquid to 70–80°C and agitate thoroughly before use. While heating, avoid localized overheating, wrap in warming blankets or use enclosed ambient temperature to uniformly bring the aromatic binding chemical up to temperature.
AROBOND 300 is to be stored indoors at 15–25°C, protected from frost and moisture. Enerlab’s aromatic binder has a shelf life of 6-months under recommended conditions.
Enerlab’s protective coatings are recognized for their consistent application and efficient yields, and the AROBOND 300 aromatic binder is no exception in terms of quality. Enerlab prioritizes the contractor application as much as the customer’s product. Choose AROBOND 300 for your next coatings and membrane project and experience the quality and technology of Enerlab’s polyurea chemistry.
Where AROBOND 300 Aromatic Binder Is Used:
