Description
ReBond 020 SBR (Styrene Butadiene Rubber) by Chemix is a high-performance bonding agent and mortar additive widely used in construction to improve the physical properties of cementitious mixes.
Here are the primary advantages of using ReBond 020 SBR:
ReBond 020 SBR
Size – 1L. 5L. 10L. 20L.
per litre price – 450/-
ποΈ Enhanced Bonding & Adhesion
-
Superior Grip: It significantly increases the bond strength between old and new concrete, making it ideal for patches and structural repairs.
-
Reduced Shrinkage: It helps control the drying process, reducing the risk of shrinkage cracks when applying thin-set mortars or screeds.
π§ Waterproofing & Chemical Resistance
-
Low Permeability: By filling the microscopic pores in the cement matrix, it acts as a waterproofing agent, making it perfect for water tanks, basements, and swimming pools.
-
Corrosion Protection: It provides a barrier against chloride ions and moisture, which helps protect embedded steel reinforcement from rusting.
-
Chemical Stability: Once cured, it offers improved resistance to mild chemicals, salts, and sewage, extending the lifespan of the structure.
π οΈ Mechanical & Workability Benefits
-
Flexibility: Unlike standard cement, SBR-modified mixes have higher “flexural” strength, allowing the material to withstand slight movements or thermal expansion without cracking.
-
Abrasion Resistance: It creates a tougher, more durable surface that is resistant to wear and tear, making it suitable for industrial flooring and walkways.
-
Ease of Use: It improves the “trowelability” of the mix, allowing for a smoother finish and better coverage over large areas.
