APPLICATION POSSIBILITIES
OF THE WATERBASED EPOXY SYSTEMS
INDUSTRIAL AND CIVIL ENGINEERING FIELDS
Waterpoxy – waterbased epoxy system
Waterpoxy – waterbased epoxy system
• Legislation • limitation of Volatile Organic Compounds (solvents, amines,reaktiv thinners etc.)
• health protection/-hygienics• products with lower health risk for workers (i. e. MAK-values)
• Saftey • limitation of flamebility-/explosion danger by unflammablecoatings
Reasons to switch to water based systems
•Epoxy resins Semi solid epoxides (oligomers) or liquid epoxy resin (high solid system ) Solid epoxy resin in emulsion ( water based system)•Hardner Switch to solvent free amino and polyamide based hardner (high solid system Switch to water based epoxy curing agent ( water based system)

When can we suggest to use a water based epoxy system ?
A good sealing properties on concrete are needed
For primer, coating or a self levelling with good adhesion retention on concrete where water is coming from the ground
We need to clean the equipment with water
When we need a ecologically friendly application

Limitation of the epoxy system:
Outdor exposure : chalking problem no available solution
Gloss behaviour : loss of gloss during apllicationsome additives help to minimise the problem
