Sikabond SBR

Sikabond SBR

SikaBond® SBR is a styrene-butadiene co-polymer, which has numerous uses as an admixture, primer, bonding agent and sealer for use in areas subject to humidity, dampness and water contact. Improves water resistance of cement mixtures by forming a reinforcing polymer that increases long term durability and flexibility of the mix on renderings and floor screeds. An admixture for cement and concrete applications, including repair and renovation, surfacing of floors and bonding generally. It contains anti-foam to control the density of cementitious mixes.

Features:

• Excellent adhesion to steel and concrete.
• Adheres well to brick, tiles, glass, asphalt, wood, expanded polystyrene and most building materials.
• Mixes may be applied in much thinner sections.
• Excellent resistance to water and water vapour.
• A high level of resistance to salt permeation.
• Increased toughness and flexibility.
• Reduced surface dusting of concrete.
• Prevents bleeding.
• Enhanced corrosion protection.
• Resistant to many chemicals and to mineral oils.
• Reduced water: cement ratio for equivalent workability.
• Improved frost and abrasion resistance.
• Freeze thaw stable passing 5 cycles at -15 °C to +20 °C.

Usage:

• Component to improve concrete repair.
• Component to improve external rendering.
• Waterproofing and tanking mortar preparation.
• For corrosion protection of steel.
• Silage pit lining and protection.
• Admixture for mortar, screeds and renders.
• Bonding agent for screeds and renders.
• Primer and sealer in tiling applications.
• Recommended for exterior use, unlike most PVA bonding aids.
• Flexibliser for cementicious-based tile adhesive when tiling on wooden or asphalt floors.
