SBR Latex Admixture
Definition:
SBR latex admixture is a styrene butadiene rubber based polymer used as an additive in concrete and mortar to improve their properties.
Composition:
It is a liquid polymer emulsion made from styrene and butadiene monomers.
Purpose:
Enhances bonding between cement and aggregates
Improves flexibility and elasticity of the mix
Increases water resistance and durability
Reduces permeability and shrinkage cracks
Applications:
Concrete repair works
Waterproofing
Tile adhesives
Grouts and screeds
Masonry mortars
Advantages:
Improves tensile strength and adhesion
Provides better resistance to chemical attacks
Enhances freeze thaw resistance
Increases abrasion resistance
Usage:
Typically added by replacing part of the mixing water in the concrete or mortar mix as per manufacturer recommendations.
