SBR (Styrene-Butadiene Rubber) waterproofing chemical is a synthetic polymer latex widely used in construction for enhancing the performance of cementitious materials. It is a milky-white, water-based emulsion that, when mixed with cement, improves adhesion, flexibility, and water resistance.
Base Material: Styrene-butadiene copolymer latex
Appearance: Milky-white liquid
Specific Gravity: Typically around 1.02
pH Value: Approximately 8
Solid Content: Ranges from 40% to 50%
Viscosity: Varies; for example, Ressi SBR 5850 has a viscosity of 30 mPas
Tensile Strength: Approximately 6 N/mm
Elongation at Break: Up to 1000%
Mixing Ratio: Commonly, SBR latex is mixed with cement and water in a ratio of 1:4:8 (SBR:Water:Cement)
Application Method: Can be applied using brushes, rollers, or trowels, depending on the specific use case
Curing Time: Allow sufficient time for curing to achieve optimal strength and water resistance
Storage: Keep in a cool, dry place, away from direct sunlight and frost
