Silane Impregnating Liquid vs. Silane Impregnating Paste: A Comprehensive Analytical Guide to Properties, Composition, and Application ​

Concrete corrosion protection, Silane Impregnating Agent material is a “star player”, but in the face of a wide range of silane impregnation liquid and silane impregnation paste on the market, many people can not tell the difference between them, today I'll give us a popular science!

Performance Comparison

• 1.Penetration and waterproofing effect 

• Silane Impregnating Liquid: small molecule structure, can penetrate to the inside of the concrete at 10mm, especially suitable for deep protection of high grade concrete.

• Silane Impregnating Paste: strong adhesion, vertical surface construction is not easy to hang, but the depth of penetration is slightly lower, about 1-4mm, more suitable for crack repair or surface protection.

2.Weathering and corrosion resistance

• Both are characterized by hydrophobicity, resistance to chlorine ions, and resistance to freezing and thawing, but the liquid performs better in extreme conditions such as marine engineering and salt spray environments due to its high purity.

• The paste, due to the thickening component, has more prominent carbonation resistance and acid rain resistance, and is suitable for acidic environments such as chemical plants and sewage treatment ponds.

Form and composition

• 1.Appearance

• Silane Impregnating Liquid:Colorless transparent liquid with high flowability 

• Silane Impregnating Paste:White paste with high viscosity

2.Principle of action

• Silane Impregnating Liquid:Deep penetration to form polysiloxane networks 

• Silane Impregnating Paste:Surface and shallow penetration, chemical bonding reactions

3.Core Ingredients

• Isobutyltriethoxysilane 

• Isooctyltriethoxysilane

Applicable Scenarios

• Silane Impregnating Liquid:Corrosive scenarios such as sea bridges, airport runways, nuclear power plants, etc., where deep penetration is sought.

• Silane Impregnating Paste:facade or topside construction, crack repair or projects with limited budgets.
