Carboxylated SBR Polymer Dispersion for Renders, Screeds & Tanking Systems
A high-solids styrene-butadiene polymer that won’t re‑emulsify like PVA, making it perfect for both internal and external applications—even on damp substrates. Widely used with Hey’di K11 tanking systems, this bonding agent enhances adhesion, flexibility, water and salt resistance, toughness, carbonation protection, and suction control on highly porous backgrounds :contentReference[oaicite:1]{index=1}.
Key Benefits
- Excellent adhesion to dense or porous substrates—concrete, brick, tile, steel, glass.
- Reduces cracking, shrinkage & dusting, while boosting frost and abrasion resistance.
- Improved water and salt resistance, ideal for external and salt-exposed applications.
- Non re‑emulsifiable—perfect for waterproofing, damp zones, and tanking systems.
- Site suction control on highly porous backgrounds—eliminates dusting.
Product Details
- Form: Milky-white dispersion with high solids polymer content.
- Pack Size: 5 kg (also available in 10 kg)
- Water-based & non-combustible; store between +5 °C and +35 °C, protect from frost/sun.
Mix Ratios & Uses
- Primer (seal dust control): 1 part SBR : 5 parts water – controls suction on porous substrates :contentReference[oaicite:9]{index=9}
- Sealer (timber edges): 1 part SBR : 3 parts water – reduces moisture ingress behind tiles (avoid tile face).
- Bonding slurry: 1:1 SBR:water with 1½ parts OPC – apply tacky before render or screed.
Extensively used in cementitious mortars, concrete repairs, and Hey’di K11 waterproof systems.
Safety & Storage
- Not classified hazardous; gloves & eye protection recommended.
- Non-irritant, rinse with water if contact occurs
- Non‑flammable; store at +5 °C to +35 °C; avoid frost & direct sunlight.
- Dispose responsibly—avoid drain contamination.
Ideal For
- Bonding renders, screeds, and waterproof coatings to porous or dense surfaces
- External and salt-exposed areas (e.g. basements, tanking systems)
- Concrete repair mortars—enhancing steel protection & carbonation resistance
- Priming/sealing timber edges before tiling or rendering
