Nano tech concrete sealer

Product Overview

Description

 

Description:
RJ-WP21 is a new generation solvent based water repellent developed by nano technology, it can impart super hydrophobic water repellency to various substrates.
After nature stone is treated by RJ-WP21 and fully cured, contact angle between water drop and substrate can reach 150°or more. RJ-WP21 will impart excellent lotus effect and self-cleaning function to the substrates.

Technical Index:

Features:
*Excellent contact angle higher than 150°.
*Good depth of penetration.
*Self-cleaning function.
*Real lotus effect.
*Suitable for various substrates, no matter alkaline substrates or neutral substrates.
*Contains no organic tin catalyst which is toxic.
*High resistance to alkalis.
*Tack-free drying.
*Rapid development of water repellency.

 

 

 

Application:
*All kinds of concrete include aerated concrete.
*Highway, airport runway, bridge & tunnel.
*Cement mortar, lime mortar & cement fiber boards.
*Interior or exterior wall

Use guide:
    Dilute RJ-WP21 with organic solvent such as petroleum solvent or solvent oils. RJ-WP21 should be diluted with a weight ratio of 1:20-1:25.
Spray or brush RJ-WP21 on substrates, or impregnate substrates into RJ-WP21 for few minutes. 1 liter RJ-WP21 can treat more than 10 m3.

Fully cured treated substrate for 1-3 days, no contact with water or fire. In summer tack-free time is only 2-3 hours, after that substrates will be water resistant, then 3 days later there will be super hydrophobic properties.

 

 

Storage:
Sealed storage under 5-30℃, Avoid contact with acids and alkali substance.
