SBR latex (Styrene-Butadiene Rubber latex) is a synthetic rubber emulsion, widely used in various industrial and construction applications due to its excellent bonding, flexibility, and water resistance properties. Here's a detailed overview:
Chemical Composition
SBR latex is a copolymer of styrene (C₈H₈) and butadiene (C₄H₆).
It's produced via emulsion polymerization, resulting in a milky-white, water-based liquid.
Properties
Property Description
Appearance Milky white liquid
pH Typically 9–10 (alkaline)
Solid Content 45%–55% (varies by manufacturer)
Particle Size 100–300 nm
Viscosity Low to moderate
Film Forming Temp ~0 to 5°C

Applications
Industry Uses
Construction Waterproofing slurries, bonding agents, tile adhesives, patching compounds, repair mortars
Textile Back-coating of fabrics, nonwoven binders
Paper Coating and impregnation
Carpet backing As a binder for carpet tufts
Paints & Coatings For flexibility and water resistance
Advantages over Natural Rubber Latex
More resistant to aging and heat
Better chemical resistance
More consistent quality due to synthetic production
Handling & Storage
Store between 5–35°C; avoid freezing
Use personal protective equipment (PPE)
Shelf life is typically 6–12 months in sealed container.
SBR Latex Admixture Is A Milky White Liquid Used In Construction To Improve The Properties Of Cement-based Materials. It Is Made From Styrene Butadiene Rubber And Acts As A Bonding Agent And Modifier. When Added To Cement Mortars Or Concrete, It Increases Adhesion, Flexibility, Water Resistance, And Durability. It Is Commonly Used In Repair Works, Waterproofing Systems, Floor Toppings, And Tile Fixing Applications. Continue
