Product Description

 

Product Description

Silway 732

Silway 732 water repellent is nontoxic and odorless. As there are relatively active Si-H bonds in the molecule, under the action of catalysts it can react with chemicals containing active groups, such as double bonds or hydroxyl groups.
Silway 732 water repellent can be converted into film and produce a resilient waterproof coating on various substrates by catalyst at low temperature. Therefore, Silway 732 water repellent has the outstanding property which prevents moisture, mildew and rust.
Besides, Silway 732 water repellent has a high permeability to water vapor, allowing the material to breathe.

Typical Applications

Typical Applications

 As a surface treatment in applications that utilize its ability to impart a water repellent surface and reduce water absorption
 For use on powders, glass, ceramic, leather, paper, metal, cement and marble

Key Features

Usage

 

HOW TO USE THE SILWAY732

Silway 732 is usually applied from dilute solution.  
Solutions are prepared by diluting Silway 732 with hydrocarbon solvents, and stirring the mixture gently until uniform. 
The extent of dilution will depend on the surface to be treated and surface properties desired.  
Curing times are much shorter at higher curing temperatures.  
Catalysts are often used to accelerate cure.
