This is the best for Waterproofing, Epoxy Flooring, Corrcion Protection, Fact repair compounds, Heat Reflective Coating and more...
"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.
