Alpha Chem SBR Bond 25 Litre the most cost effective option from Cromar a liquid, which has numerous uses both internal and external as an admixture, primer, bonding agent and sealer.

Cromar Alpha Chem SBR Bond is a water‐based non‐ionically stabilized hydrolysis‐resistant dispersion of a carboxylated styrene butadiene copolymer.

Sbr Bond is a white Polymer Emulsions used extensively by the building industry for many years used as an admixture for cement and concrete applications,

including repair and renovation, surfacing of floors and bonding generally.

SBR contains anti-foam to control the density of cementitious mixes.

SBR Bond is used for modification of hydraulic blinders in common building applications including repair mortar, flooring, rendering, bonding, mineral sealing slurries and as cement based adhesive.

At higher temperatures 25 degree C the addition of SBR Bond prevents a premature stiffening of the mortar allowing for mor time on the job and less wastage.

Free from plasticizer and other additives which can migrate.

Alpha Chem SBR Bond Benefits

• 25 Litre more economical
• Greatly improved adhesion to a wide range of substrates including dense concrete, steel, tiles etc.
• Mixes may be applied in much thinner sections.
• Excellent resistance to water and water vapor.
• Aids in the adhesion of self-levelling compounds to the base surface.
• Gives A high level of resistance to salt permeation.
• Much improved toughness and flexibility.
• Reduced surface dusting of concrete.
• Greatly improved resistance to many chemicals.
• Reduced water cement ratio for equivalent work ability.
• Improved frost resistance.
• SBR Bond is also freeze thaw stable.

SBR Bond Typical Uses

• Admixture for mortar, screeds, renders.
• Bonding agent for screeds, renders, self-Levellers.
• Primer and sealer in tiling applications.
• Flexibliser for cementicious based tile adhesive when tiling on wooden, asphalt floors.
• In addition, SBR Bond has the advantage over PVA bonding aids in that its not adversely affected in wet conditions and is recommended for exterior use.
