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
Tensile Strength High (enhanced when cured or blended)
Water Resistance Excellent when fully cured
Key Features
Improves flexibility and reduces cracking in mortars and concrete
Enhances adhesion to various substrates
Improves water resistance and reduces permeability
Compatible with cementitious materials
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.
