Details
Emulsione Epossidica 723 is a protective coating based on two-component water-emulsified epoxy resins. Its cured film has high abrasion resistance and is completely odourless. Emulsione Epossidica 723 is a protective coating (type C) for the surfaces of concrete structures in accordance with UNI EN 1504-2, and may be used in accordance with the following principles as set out in UNI EN 1504-9: Protection against the risk of penetration (principle 1), moisture control (principle 2) and increased resistivity (principle 8).
Instructions for use
Preparation for laying
The substrate must be solid, free from loose particles and cement residue, clean and even.
Product preparation
Mix the two pre-measured components thoroughly for a few minutes in their original containers, pouring component B into the container for component A until a perfectly homogeneous mixture is obtained. The mixed product remains workable for approx. 60 minutes.
Application instructions
‘Emulsione Epossidica 723’ is applied by brush, roller or airless spray at temperatures above +10 °C. It is recommended to apply at least three coats of no less than 150 g each, allowing sufficient time for the water to evaporate (approx. 2 hours at 20 °C) between successive coats. For spray application, the paint may be thinned. In this case, add up to 10% water to Component A and shake well. Then mix the two components together. In enclosed spaces, ensure adequate ventilation. The applied film must be protected from rain and accidental contact with water within the first 6 hours to prevent re-emulsification or washing off.
Cleaning
Tools should be cleaned with water – preferably hot – immediately after finishing the job. If the application takes several hours, it is advisable to give the brush, roller or spray gun a quick clean every 2 hours. An existing coat of ‘Emulsione Epossidica 723’ can be recoated after sanding.
Storage
Emulsione Epossidica 723 remains stable for at least 18 months if kept in its original, unopened packaging and stored at temperatures between +15 °C and +30 °C. It must be protected from frost.
Warnings
- Emulsione Epossidica 723 should not be applied at temperatures below +10 °C.
- If stored for more than one day at temperatures below approximately +15 °C, Component B may become coagulated due to the crystallisation of the epoxy resin it contains. This phenomenon is not a defect and can be easily remedied by bringing the affected containers to +40 °C overnight. The product must be stored at temperatures above +15 °C.
