N-Octyltriethoxysilane Silway740

Description

Silway-740 is high purity, undiluted N-octyltriethoxysilane. Treated substrate with OTES will have good water repellent performance and retain the original appearance.

Alkaline environments, such as pouring concrete, will stimulate the reaction and accelerate the formation of hydrophobic layers. After using Silway-740 silane, the protection effect would be obvious on highly alkaline new concrete (less than on year old), but be poor on old concrete or neutral substrates.

Usage

• In order to achieve optimal application results, new surfaces that are still unsoiled must be cleansed of coarse particles and dust deposits by sweeping or, if necessary, using compressed air. Surfaces already weathered, and those heavily soiled by oil, rubber residue, etc., must first be cleaned using superheated steam or high-pressure water before commencing treatment.

• It is strongly recommended carry out preliminary tests to determine the optimum quantity for particular application.

• Keep container tightly closed once opened
