Macropoxy 2600

The intermediate layer

Sherwin-Williams’ Macropoxy 2600 is an innovative high solids, epoxy intermediate coating solution for use in multi-layer systems in corrosive environments. Formulated to be an optimum intermediate solution and meet the highest performance criteria while offering superior application, it also helps reduce costs right across the value chain.

Macropoxy 2600 comes with conventional pigmentation, or pigmented with micaceous iron oxide for enhanced overcoating properties and excellent barrier protection – especially on sharp edges, corners and welds. Specifiers, contractors and applicators looking to exceed the highest productivity expectations while improving efficiency and quality should also note the low levels of Volatile Organic Compounds (VOC).

Product Highlights

• Excellent corrosion resistance as part of certified systems according to ISO 12944-6:2018 up to CX on steel for two- or three-coat systems, and Norsok M501 System 1 as part of a primed system.
• The high film build and wide Dry Film Thickness range 100 – 250 µm allows for a reduction in the number of coats and simplifies specifications
• VOC is 174 g/L to meet stringent VOC requirements, even when thinned
• 82% +/-3% volume solids
• Optimised at low temperature for site applications up to -5°C

Macropoxy 4600

The primer

Sherwin-Williams’ Macropoxy 4600 is an innovative high solids, multi-functional epoxy zinc phosphate coating solution for the protection of carbon steel, stainless steel and galvanised surfaces. Formulated to be the optimum primer solution and meet the highest performance criteria while offering superior application, it also helps reduce costs right across the value chain. Specifiers, contractors and applicators looking to exceed the highest productivity expectations while improving efficiency and quality should also note the low levels of Volatile Organic Compounds (VOC).

Product Highlights

• High corrosion resistance with certified systems according to ISO 12944-6:2018 up to C5 on steel for two- or three-coat systems 
• The high film build and wide Dry Film Thickness range 75 – 250 µm allows to reduce the number of coats and simplify specifications
• Optimised at low temperature for site applications up to -5°C
• VOC is 216 g/L to meet stringent VOC requirements, even when thinned
• 80% +/-3% volume solids
