Description

AQUAPURE is a two-component solvent free polyamine cured epoxy system with outstanding corrosion protective properties. Binding agents contain modifying components to ensure excellent adhesion properties on most surfaces. Pigmentation consists of specially developed extenders and coloring pigments, which as a combination gives excellent chemical-, abrasion-, heat- and impact resistance together with a diffusion tightness far beyond what is known for similar products. The product cures rapidly and the surface may be immersed shortly after application. It also cures effectively at temperatures below freezing.
AQUAPURE is moisture tolerant, but application should nonetheless not be done on wet surfaces in order to obtain optimal adhesion values. One should also try to avoid application when relative humidity is above 85% unless this is absolutely necessary. In such cases operation should be followed up closely together with the client or his appointed representative to ensure that surface temperature is above dew point during application.

Composition

AQUAPURE is a two-component system. Both the A and B component are delivered predosed in separate packaging. The base or A component contains non-crystallisable epoxy resins. The B component contains the polyamine hardener complex, high-tech modifying agents, lamellar abrasion/impact/heat resistant fillers, and coloring pigments.

Application
AQUAPURE is an outstanding coating designed to protect metal surfaces from corrosion and may also be used on concrete structures. However, an optimal result requires a well qualified crew when it comes to surface preparation and product application. Under normal conditions the steel surface shall be abrasive blasted in accordance with SSPC SP-10, using abrasive of a size which will produce a surface profile height of 1-3 mils. It can be applied in one single layer up to a thickness of at least 25 mils depending on ambient temperature, by use of two-component high-pressure airless spray equipment. Product temperature should be kept at about 95 degrees F by means of indirect controlled heating of both pump containers and hoses. Prior to spraying, touch up should be done manually on generally difficult areas such as sharp edges, bolt heads, pittings etc. Overcoating can if necessary be done immediately, or within 48 hours. Although interadhsesion shows outstanding results even for longer intervals, light grinding might be an option depending on conditions.
