Silicone Hydrofobe Poeder

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.

Belangrijkste voordelen

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

Typical Applications

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

Poederontstopper

Ontschuimer

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.

Belangrijkste voordelen
