• Anti-corrosion protection against the attack from strong chemical agents such as diluted alkali and acid solutions.
• Adhesion promoter on metal surfaces for subsequent coating systems.
• Excellent adhesion on metal substrate.
• It reacts even with steel which has been sandblasted to white metal or over only partially rusted surfaces.
• Water-based liquid, solvent-free and non-flammable.
• One-component product, easy and ready to use.

Apply two coats, the second one when the first coat is dry to touch (between 2 – 3 hours at 20ºC). Avoid staining the concrete around the reinforcement. More successive coats can be applied if required.
Do not apply below 5 ºC of if such temperature is expected within 24 hours. Do not apply if rainfall is expected within 24 hours. Do not apply on frosted or frozen surfaces.
MAXREST® PASSIVE can be coated with other epoxy or polyurethane coatings 24 hours after application.
Clean with water all tools and equipments immediately after use. Once it hardens, product can only be removed by mechanical methods.
Estimated consumption of MAXREST® PASSIVE is 0,15 kg/ m2 per coat, for a dry film thickness of 50 microns, in order to achieve a total consumption of 0,3 kg/m2 in two coats. Consumption may vary depending on texture and surface conditions, a preliminary test on-site will determine consumption exactly.
MAXREST® PASSIVE is supplied in 500 gram, 1 kg, 25 kg and other amounts on application.
Twelve months in its original unopened packaging, in a dry covered place, protected from humidity and frost with temperatures above 5 ºC.
