Advanced Hybrid Cycloaliphatic (AHC)
Definition - What does Advanced Hybrid Cycloaliphatic (AHC) mean?
This is a solid epoxy designed from the upgrade of cycloaliphatic amines by chemistry through combining it with specialty aliphatic amines. The chemistry is used in the manufacturing of two-component epoxy coatings and primers. It is used in the lining technology of tank containments and pipes to solve the problem caused by leakages, cold climates, short production schedules and corrosion. It is mostly used in a single coat application.
Corrosionpedia explains Advanced Hybrid Cycloaliphatic (AHC)
Cycloaliphatic amines are made from a six-member carbon-atom ring in the backbone of the curing agent, whereas the aliphatic amines are straight-chained. It is characterized as a solvent-free and low-odor epoxy. Its self-priming feature makes it useful in spray applications.
Therefore, the cross-linking of these two polymers helps in providing superior properties and strengths such as:
- It provides excellent adhesion and sealing properties on steel or concrete pipes and tanks.
- It has an improved resistance to chemical and UV degradation; it can withstand constant immersion in chemicals (organic solvents, dilute acidic exposures and caustic environments).
- Epoxy made from this chemistry is user-friendly in handling and application without runs or sags; increased flexibility and durability.
- It provides improved surface hardness, adhesion and abrasion resistance.
- It contains fast-curing features at a low temperature of 0°C.
