SHP

Silicone Hydrophobic Powder is a free-flowing, highly effective water-repellent additive based on silane/siloxane technology. It significantly reduces water absorption while maintaining vapor permeability, improving durability and weather resistance in cement-based and gypsum-based materials.

Avantages Clés

Excellent Water Repellency
Reduced Water Absorption
Maintained Vapor Permeability
Improved Weather Resistance

Applications typiques

Dry-mix mortars Exterior wall systems Tile adhesives & grouts Renders and plasters
Défroisseur en poudre
Efficient Air Control
02

Défroisseur en poudre

Détartrant

Powder Defoamer is designed to effectively eliminate and control unwanted air bubbles during mixing and application. It improves density, surface quality, and mechanical strength of mortars and cementitious systems without negatively affecting workability.

Avantages Clés

Rapid Defoaming Performance
Reduced Air Entrainment
Improved Surface Appearance
Enhanced Mechanical Strength

Applications typiques

Tile adhesives Self-leveling compounds Cement-based mortars Gypsum formulations
