What is SBR latex used for?

What is SBR latex used for?

SBR LATEX is a carboxylated styrene butadiene copolymer latex admixture that is designed as an integral adhesive for cement bond coats, mortars and concrete to improve bond strength and chemical resistance.

Where is SBR latex used?

SBR Latex is largely used in construction industry nowadays. This is used as an admixture for Cement slurry, Cement mortar & Concrete to improve some of their properties. In Cement slurry: When it is used with cement slurry it works as a bonding agent.

Who makes SBR rubber?

Some major manufacturers of SBR rubbers are Firestone, Dynasol, Eni, Asahi-Kasei, LG Chem, GoodYear, JSR, and Lanxess.

How do you mix SBR latex?

Mix SBR LATEX (M) : water in a 1 : 1 ratio. Use a maximum of 25 ltr of this solution in a mix containing 50 kg of cement and 150 kg of sand. This will yield approximately 100 litres of mortar which will cover 10 m2 to a thickness of 10 mm.

What is SBR bonding?

SBR Bond is a latex based, water resistant bonding agent and admixture for use in areas subject to humidity, dampness and continuous water contact.

How SBR is produced?

Solution SBR is produced by termination-free*, anionic solution polymerization of styrene and butadiene with alkyl lithium initiator (e.g., butyllithium) in a hydrocarbon solvent, usually hexane or cyclohexane.

Is SBR rubber waterproof?

SBR rubber is highly regarded for its excellent abrasion resistance, crack endurance and positive ageing characteristics. It also delivers good compression set and water resistance, as well as favourable bonding and heat-ageing properties.

Does SBR absorb water?

SBR is tolerant of oil-contaminated air, water, industrial water and glycol. This grade of rubber can endure temperatures ranging from -50 to +100 °C and is suitable for damping, insulation and shock absorption.

Is SBR the same as neoprene?

SBR foam is similar to neoprene foam and can be lined with nylon or polyester to get the same appearance as a normal neoprene wetsuit. However, SBR foam has poor elongation capabilities and is hardly ozone or chemical resistant. This is why manufacturers mainly use SBR foam in very cheap and poor quality wetsuits.

Is SBR rubber vulcanized?

All types of SBR are vulcanized using the same vulcanization agents as for natural rubber. Styrene-butadiene rubber can be vulcanized using sulfur, sulfur donor systems and peroxides.

How do you SBR a concrete?

Mix 1 part by volume SBR with 1.5 parts fresh Portland cement to produce a stiff grout. Scrub this grout on to the pre dampened concrete or wall. DO NOT allow to dry prior to the application of subsequent layers.

How do you use SBR on paving slabs?

Add the SBR to the dry cement mix slowly while mixing to avoid lumps, continue until you achieve a gloopy consistency that coats the back of the paver. If the paving is very light in colour and is prone to absorption, we do recommend using a white cement, this will minimise the risk of discoloration.
