The function of a hydrophobic agent
Product Metrics:
Appearance: White, free-flowing powder
Composition: silicon oxide compounds, dispersion and adsorption complexes
Viscosity: Light, freely flowing powder
Apparent density: 300–350 g/L
Fineness: 98% pass 200 mesh
Function:
1. Prevent liquid water from penetrating cured cement-based materials via surface or capillary action;
2. Significantly reduces the water absorption of cement-based materials, even when in direct contact with water for more than 24 hours.
3. When the addition level is 0.2% to 2.5% by weight of the dry mix, there is virtually no adverse effect on the compressive strength of the material.
Addition amount and method of use:
1. It is recommended to add 0.5%–1.5% by weight of the total dry powdered building materials to achieve excellent waterproofing and impermeability performance.
2. It can be blended with other dry-powder construction materials without compromising performance.
For best results, please test beforehand.
By employing G-Technology’s carrier and controlled-release technologies, the active ingredients are released in a timely manner upon contact with water and, following curing of the substrate, form a hydrophobic protective layer. As a hydrophobic additive, it is suitable for dry-mix mortar systems based on cement and mineral materials, effectively inhibiting capillary and pore absorption of water within the material, thereby significantly reducing the substrate’s water absorption and imparting outstanding hydrophobic performance. It is particularly well suited for grouts, putties, waterproof mortars, as well as skim coats and decorative mortars used in exterior thermal insulation systems.
