EpiMax 225 Construction Grade Epoxy Binder is a low viscosity, high strength epoxy system which adheres tenaciously to all forms of prepared concrete surfaces. Epoxy renders, mortars and grouts can all be produced easily in the field with EpiMax 225.

1. Positioning
EpiMax 333AR High Build Acid Resistant Coating is an exceptional two-pack solventless, novolac based coating system suitable for a variety of applications including acid-proofing of tanks, secondary containment structures and wastewater asset protection.

2. Key Uses
• Wastewater infrastructure
• Secondary containment bunds
• Chemical processing areas
• Effluent channels and pits
• Industrial floors subject to chemical exposure
Typically applied as a multi-coat lining system to achieve required DFT and durability.
Used where conventional epoxy systems are insufficient.

3. Typical Substrates
• Concrete
• Steel

4. Typical Thickness Range
• Nominal system DFT: 600–1000 μm
• Minimum DFT: project-specific (commonly ≥650 μm)

5. Key Properties
• Novolac epoxy chemistry → high chemical resistance
• High cross-link density → low permeability
• Excellent adhesion to prepared concrete and steel
• Solvent-free system → high film build capability
• Suitable for immersion service

6. Where It Fits (System Context)
Typical system combinations:
• Primer: EpiMax 225
• Epoxy render: EpiMax 225 + processed quartz
• Build / lining: EpiMax 333AR
