PAVIRESISTANT TIXO A+B
Epoxy product for chemical resistant coatings
Used to make waterproof protections for conduits and containment tanks, it is resistant to contact with aggressive chemicals such as acids, bases and solvents, especially ethyl acetate.
Type: Chemical resistant coverings
Description
Two-component product based on epoxy resin used in combination with cycloaliphatic amine hardeners.
Formulated at 90% by weight of dry residue, used to make coatings resistant to contact with aggressive chemicals (acids, bases, solvents in particular ethyl acetate).
Use
Waterproof protection of ducts and containment tanks.
Support
The substrate must have a minimum compressive strength of 25 N/mm2 and a tensile strength of 1,5 N/mm2
Preparation of the support
Concrete bases must be solid, dry (seasoned if newly built), leveled, absorbent, not polluted by oils, detergents, powders or other substances.
Evaluate the most convenient type of mechanical preparation (sandblasting, hydrowashing) and then apply a recovery of ECOFONDO on a regularized support.
Application
At the time of application, combine the two components in a single container and mix carefully with appropriate equipment.
Quickly use the entire content. When emptying the container avoid scraping the edges and the bottom, as there may be some product not perfectly blended.
Apply the product with a roller or brush with a consumption of 300-600 gr/m2.
Warnings
PAVIRESISTANT coatings exposed to sunlight may fade or change color with a turn towards yellow; this fact does not affect the performance of the coating in any way.
Between different production batches of the same color there may be slight differences: when possible use material from the same production batch.
For low temperature applications, the material can be heated to 25°C for easy application and catalysis (viscosity decrease).
Tones on yellow, orange or some reds may require more coats to obtain a good covering effect.
Product for professional use, the buyer undertakes to follow the above warnings in the application of the purchased product and the instructions in the safety data sheet.

| (*) PAVIRESISTANT TIXO applied at substrate temperatures below 15 °C could stain in contact with water or water-basedpreparations and form whitish spots. Such a defect in chemical resistance is caused by incomplete cross-linking. Therefore, PAVIRESISTANT TIXO should be applied at a media temperature of not less than 15 °C and at least 3 °C above the condensation temperature. | |
