"Polyurea" is derived from the reaction product of at polyisocyanate component and an amine-terminated vesin bleand. Compound with two part system there.
- One partis Isocyanate component "reactive isocyanate groups (-NCO)".
- One port is a Resin blend component "reactive group is amine (primary or secondary) (-NH2 or - NH-).
- Reaction of the two components yields aurea linkage.
!!! Polyurea is not a Poly urethane
!!! Polyurea does not contain a catalyst
!!! Poly urea improves moisture resistance
!!! Polyurea cure not affected by temperature or humidity
Characteristics
- Fast, consistent reactivity / no catalysts
- Relative environmental processing insensitivity
- Excellent mechanicsl properties
- Good adhesion to a variety of substrates
- 100% solids formulations
Advantage
- Single coat application
- Suitable for steel and concrete decks
- USDA & FSIS approved
- Potable water ANSI/NSF61 approved
- Flame Retardant
- In-service resistant to to cold and heat -40C to +230C
- Flexible
- Greater than 150๔ elongation
- Long life expectancy
- Will not hydrolyze or biodegrade
Long Life Expectancy
- After exposure to a total of 3800 hours, using UVB-313 bulbs at 50 C, the physical property retention was at least 80%
- Unlike crystalline nature of polyurethane and epoxy, BDM is amorphous in nature. It has 2 distinct Tg's or Glass Transition Temperature., with a low temperature noted at about -50 C to 260 C. This would be the performance range, temperature wise.
- BDM is saltwater resistant. A major construction project in Boston under the direction of Bechtel, Parsons & Brinkerhoff specified our system on the exterior of a concrete tunnel of an immersed tube/tunnel.
- When exposed to an elevated temperature of 80 C, this nominal temperature has little to no effect on the polymer.
- Based on testing, flexibility of the system, chemical resistance and thermal properties, our polymer is expeced to survive a minmum 75 years in saltwater application area.
