COATIX® EP 1130 Primer
COATIX® EP 1130 Primer is a two-component, solvent-free, low-viscosity, epoxy resin-based surface impregnation primer. It has good penetration properties, is resistant to chemicals and has high mechanical strength. It fills the capillary pores of concrete floors, increases their strength and acts as a bonding bridge for subsequent epoxy coatings or paints. It can also be used on its own to prevent dusting of concrete.
Areas of Use
• Factories, warehouses and shopping centres
• Workshops and aircraft hangars
• Schools and hospitals
• Pharmaceutical and food industry facilities
• Laboratories and car parks
• Treatment plants
• Areas with heavy forklift traffic and corrosive chemicals
• As a primer coat before self-leveling and epoxy coatings; on its own to prevent dusting of the floor
Advantages
• Solvent-free; provides low emissions during application
• High penetration thanks to its low viscosity
• High resistance to chemicals
• High mechanical strength
• Moisture-tolerant; can also be applied on damp surfaces
• Fills the capillary pores of concrete floors
• Forms a strong bonding bridge for subsequent epoxy coating/paint coats
• Prevents dusting of concrete when applied on its own
