Product introduction

High-solid epoxy high-build coating 3217 is a polyamideadduct-cured multi-functional epoxy high-build coating withhigh solid content. its paint film provides good toughnesswettability and curing property at low temperature.

Recommended applications

It can be used as a self-priming surface-resistant coating system or asan intermediate coat or topcoat in systems requiring low VOCs andhigh film formation. Additionally it can be used as a low surfacetreatment primer to enhance the adhesion and toughness of thewhole coating.

Construction conditions

New steel: Sand blasting to Sa2.5 and Medium(G) surfaceroughness(ISO 8503-2).

Steel coated with shop primer: Cleaning for sand blasting orgrinding with an elastic grinding wheel to polish the corrodedparts to St3.

Use welding, flame cutting or hot work to correct the burnedparts: Remove the welding slags and spatters, grind and then polish it to St3 with an elastic grinding wheel.

The substrate must have a temperature >3°C above the dewpoint. The environment should be <85%RH.

Use this product only when the painting and curing can becarried out normally at above -10°c. The painting surface mustbe clean and dry.
