SYNONYMS:
ARADUR® 20317, Aradur 20317, Formulated Aliphatic Polyamine Adduct, Aliphatic Polyamine Hardener, Epoxy Curing Agent, Epoxy Hardener, Formulated Polyamine Adduct, UV-Resistant Epoxy Hardener, Low-Yellowing Epoxy Hardener

Aradur 20317 is a formulated aliphatic polyamine adduct epoxy curing agent developed by Huntsman Advanced Materials for high-performance, solvent-free epoxy coating systems.
Aradur 20317 is specifically designed to provide excellent UV resistance, extremely low yellowing, low chalking tendency, and superior surface appearance, making it particularly suitable for decorative flooring and architectural coatings.

Unlike conventional aliphatic amine curing agents, Aradur 20317 produces nearly colorless cured films with excellent long-term color stability while maintaining high mechanical strength and good chemical resistance.
Aradur 20317 is recommended for use with liquid epoxy resins such as ARALDITE DY-31 CMR-Free, ARALDITE DY-C, and EPALLOY 5000 to formulate decorative, solvent-free flooring and protective coating systems.

Aradur 20317 is a formulated polyamine adduct used as an epoxy curing agent, manufactured by Huntsman.
Aradur 20317 is highly valued in decorative coatings, composites, and adhesives for its exceptional resistance to yellowing, minimal chalking, and excellent mechanical stress resistance.
Aradur 20317 is a formulated polyamine adduct.

USES and APPLICATIONS of ARADUR 20317:
Aradur 20317 is primarily used as a curing agent for solvent-free epoxy coating systems, especially decorative floor coatings and architectural flooring applications where color stability is essential.
Aradur 20317 is widely used in commercial buildings, shopping centers, hospitals, laboratories, schools, public facilities, pharmaceutical plants, food processing areas, and industrial floor coatings requiring attractive appearance together with high mechanical durability.

Aradur 20317 is also suitable for protective coatings on concrete, cementitious substrates, and metallic surfaces where excellent UV resistance and low yellowing are desired.
Because of its smooth surface finish and low tendency to water spotting, Aradur 20317 is frequently selected for decorative self-leveling epoxy floors, seamless flooring systems, clear epoxy topcoats, and premium protective coatings.

BENEFITS of ARADUR 20317:
Aradur 20317 offers outstanding color stability compared with conventional epoxy curing agents, making it particularly suitable for decorative applications where appearance is critical.
Aradur 20317's exceptional resistance to yellowing and chalking allows coatings to retain their original appearance even after prolonged UV exposure.
Aradur 20317 produces smooth, uniform coating surfaces with low water spotting and excellent gloss retention.

In addition, Aradur 20317 provides excellent mechanical strength, abrasion resistance, adhesion, and chemical resistance, resulting in durable flooring and protective coating systems with long service life.
Aradur 20317's solvent-free formulation also contributes to low VOC emissions and environmentally responsible coating formulations.

CHARACTERISTICS of ARADUR 20317:
Aradur 20317 is a modern formulated aliphatic polyamine adduct specifically engineered to produce decorative epoxy coatings with exceptional long-term appearance.
One of Aradur 20317's most significant characteristics is its extremely low tendency to yellow and chalk, even after prolonged exposure to ultraviolet radiation.
Unlike many conventional epoxy curing agents that discolor during service, Aradur 20317 enables the production of almost colorless cured films with excellent gloss retention and superior visual quality.

Aradur 20317 also provides excellent compatibility with liquid epoxy resins, allowing formulators to prepare solvent-free coating systems with smooth surfaces, low water spotting, high mechanical strength, and outstanding durability.
Aradur 20317's balanced curing profile provides sufficient working time while producing coatings that resist abrasion, mechanical stress, and environmental exposure.
