Hydrophobic Polymer Powder

Guudpoly Hydrophobic polymer powder is a free-flowing, spray-dried additive designed for dry-mix construction materials. It disperses in water to form a highly water-repellent, flexible, and durable polymer film integrating hydrophobic property and excellent waterproof performance.

🌱 Core Advantages

Superior water repellency: –Creates a high-contact-angle surface that beads water, drastically reducing capillary water absorption and moisture ingress.

Alkali & chemical resistance: – Stable in high-pH cementitious environments; resists saponification and degradation.

Vapor permeability (breathability): –Blocks liquid water while allowing water vapor to escape, preventing blistering and efflorescence in exterior systems.

Enhanced durability: – Improves resistance to freeze-thaw cycles, UV aging, salt weathering, and chemical attack, extending service life.

Strong adhesion & flexibility: – Boosts bond strength to concrete, masonry, and insulation boards; bridges cracks and absorbs structural stress.

🧱 Key Application

Exterior insulation & finish systems (EIFS/ETICS): –Basecoats, renders, and facade putties for water protection and thermal performance.

Tile adhesives & grouts: – For bathrooms, kitchens, and swimming pools; prevents bond failure and efflorescence.

Cementitious waterproofing: – Slurries, membranes, and coatings for basements, roofs, balconies, and terraces.

Concrete repair mortars: – Adheres to aged substrates; reduces water penetration and corrosion of reinforcement.

Waterproof Dry-mix formulations: – Compatible with masonry mortars, joint fillers, and crack isolation membranes.
