Cycloaliphatic and Aliphatic Amines
Cycloaliphatic Amines
Admark offers low viscosity modified cycloaliphatic amine adduct hardeners for epoxy resin based lacquers and coatings.
The Cycloaliphatic hardeners are used in combination with liquid Epoxy resins, or epoxy resin modified by means of reactive as well as non-reactive diluents. Ideal for high solid protective coatings, self-levelling floor coating and structural steel.
Cycloaliphatic Amines exhibits good film hardness and film properties of excellent gloss. Very good chemical resistance and mechanical properties especially at heat cure temperature and good elevated temperature performance.
Typical Applications
- High solids coatings
- Flooring
- Chemical resistant linings
- Secondary containment
- Adhesives
General Performance
- Colorless liquid
- Good chemical resistance
- Color stability
- Low viscosity
- Good high temperature physical and electrical properties
- Moderately high heat distortion temperature
- Excellent mechanical properties
Aliphatic Amines
Aliphatic amines are usually fast curing, low viscosity, and good chemical resistance to the applied system. However, it is usually modified to eliminate problems caused by the objectionable volatility of the amines. The aliphatic polyamine cured system is resistant to attack by alkalies, solvents and some inorganic acids; they are less resistant to most organic acids.
Typical Applications
- Civil Engineering – patch repair systems
- Flooring
- High solids coatings
- Adhesives
- Wet lay-up laminating
- Small electrical encapsulation
- Acceleration of other amine curing agents
General Performance
- Low viscosity.
- Developed to improve certain characteristics such as pot life, faster cures and easier handling.
- Excellent cured resin physical characteristics including chemical and solvent resistance.
- Good long-term retention of properties.
- Short-term exposure at high temperature can be tolerated.
- Excellent resistance to aqueous alkali.
- Strong organic acids such as acetic acids not recommended.
- Good solvent resistance.
