What is Polyurea - basic chemistry:

Unique formulation:
- reaction of isocyanate (A) & polyamine (B), terminated -NH2 - no polyols, no hydoxyl termiated -OH
- no catalysts
- no solvents
- no VOCs (Volatile Organic Compounds)



Isocyanate (Prepolymer):

• Aromatic
   - General purpose
   - Poor weather/color stability

• Aliphatic
   - Generally more expensive
   - Good weather/color stability
          

Resin (Amin)

• Polyetheramines
   - Produced first commercial polyureas in 1980s
   - Used extensively

• Polyaspartic amines
   - Commercialized in late 1990s
   - variety of cure speeds
   - Weather/color stability
   - Often used as top coat (10-15 mils) on other,
   - general purpose coats
