Epoxy gum frameworks comprise of two sections, an “A” side and a “B” side. The B side, otherwise called the “hardener,” is the epoxy’s relieving specialist; the curing agent is liable for responding with the epoxy bunches contained in the A side of the epoxy sap. The response of the curing agents with the epoxy saps brings about hard and thermosetting materials. These thermosetting materials are frequently utilized as coatings and as parts in completed items, like cements or mixtures.
The sort of epoxy curing agent impacts both the relieving qualities of an epoxy tar framework and the last thermosetting presentation. Fix qualities incorporate things, for example, pot life and meager film fix rate, while thermosetting execution incorporates things, for example, hardness, glass progress temperature, and elasticity. The following is an outline of the sorts of epoxy curing agents that Huntsman Advanced Materials fabricates:
- Polymercaptan Curing Agents
- Polyamide and amidoamine relieving specialists
- Amine Curing Agents
- Aliphatic Amine Curing Agents
- Cycloaliphatic Amine Curing Agents
- Sweet-smelling amine relieving specialists
- Phenalkamine Curing Agents
POLYMERCAPTAN CURING AGENTS
With unequaled green strength advancement, Polymercaptans are appropriate for time-basic applications. Polymercaptan resin fix rates can be changed in accordance with be pretty much as quick as 30 seconds (gel time) or as quick as 30 minutes (gel time). Polymercaptan relieving specialists are known to show decreased reliance on restoring temperature; this makes polymercaptans particularly important in a limited scope and low-temperature applications.
POLYAMIDE AND AMIDOAMINE CURING AGENTS
Polyamide and amidoamine epoxy hardeners depend on a spine of aliphatic chains associated by amide bonds. This extraordinary spine grants durability to the last thermoset; this sturdiness converts into execution increments considered in such things to be influence strength, break opposition and substrate grip.
Polyamide and amidoamine specialists contrast principally in their particular viscosities; polyamides are substantially thicker than amidoamines. Both relieving specialists offer brilliant water opposition in the last thermosets. Great water obstruction, joined with durability, make polyamide and amidoamine curing agents the favored decision in applications like glues, preliminary coatings, dampness hindrance coatings, and electrical preparing.
AMINE CURING AGENTS
Many epoxy curing agents being used today are of the amine assortment. Amine relieving specialists are generally utilized because of their viable fix rates and extreme thermosetting execution. There are three fundamental sorts of amine relieving specialists:
ALIPHATIC AMINES CURING AGENTS
Amines in view of straight aliphatic chains that respond quickly at room temperature.
Normal applications incorporate
- Level
- Concrete
- steel coatings
CYCLOALIPHATIC AMINES CURING AGENTS
Cyclic aliphatic chain-based amines showing enhancements in synthetic obstruction and glass progress temperatures
Normal applications incorporate
- Level
- Concrete
- steel coatings
Fiber Reinforced Composite Parts with Low Heat Resistance Requirements
Fragrant AMINE CURING AGENT
Amines in light of sweet-smelling affixes prompting high glass change temperatures.
Normal applications incorporate
- Fiber Reinforced Composite Parts
- High temperature
- Substance obstruction coatings
PHENALCAMINE CURING AGENTS
Phenalkamine curing agents depend on a bio-inexhaustible cardanol spine. Because of this cardanol-determined spine, phenylamine have fantastic water obstruction and hardness like those of polyamides and amidoamine; phenalamines, in any case, have further developed low-temperature fix execution. This higher low-temperature fix execution makes phenalkamines famous in outside covering applications, considering longer application seasons in chilly environments. Normal applications incorporate marine coatings, modern preliminaries, and dampness boundary coatings.
