ARALDITE® GZ 540 X 90

• Good gloss, flexibility and adhesion
• Good moisture resistance
• Excellent corrosion resistance
• Easily soluble in solvents to obtain desired viscosity and solids
• Excellent resistance to dilute acids, alkalis and sea water

High solids coatings with excellent corrosion protection. Can be formulated as primers and topcoats.Typical uses of these resins include formulations for maintenance coatings, marine finishes, tank linings, floor finishes, concrete coatings and interior pipe coatings.

The following types of curing agents are typically used for room temperature curing coatings. The epoxy resin and the curing agent are stored separately and mixed shortly before use. These hardeners include:

• 1-Formulated polyamines and cycloaliphatic amine hardeners. Used at levels of ~12 to 25 phr. Two component systems using these curing agents are characterized by fast dry times and short pot life. Examples are Aradur® 943 and Aradur® 837.
• 2-Formulated amidoamines hardeners. Used at levels of ~25 to 100 phr. High viscosity polyamidoamines are reduced with organic solvents to give better handling properties as solvent-containing, two-component systems. Low viscosity polyamidoamines are used without additional dilution in high solids formulations. Examples include the following products:
   

  High Viscosity	High Solids
  Aradur® 815-2 X-70	Aradur® 283
  Aradur® 825-2	Aradur® 360
  Aradur® 840-2	Aradur® 250

• 3-Phenalkamine hardeners. Used at levels of ~28 - 45 phr. The products offer fast cure speeds at temperatures as low as 5°C, excellent adhesion and water resistance, good chemical resistance and relatively long pot life. Examples include Aradur® 3440, Aradur® 3442 and Aradur® 3460.
