Bonding Agent (SBR Latex)

SBR latex bonding agent for repair mortars and cementitious overlays—improves adhesion, cohesion, and flexibility in compatible systems.

Grade selection typically depends on solids content, viscosity, intended use (bond coat vs. mortar modifier), substrate condition, and site temperature/humidity.

Site note: Surface prep and curing practices are often the biggest drivers of bond performance. Share substrate condition (dry/damp, roughness, contamination) and your repair system so we can align the correct SBR profile.

Product overview

SBR latex is commonly used as a polymer modifier and bonding aid in cementitious systems. In compatible repair mortars, slurries, screeds, and renders, it can improve adhesion to prepared substrates, reduce water absorption, and increase flexibility—supporting more durable repairs under service conditions.

What it does

Improves bonding, cohesion, and workability in compatible cementitious mixes; supports reduced cracking tendency via improved flexibility.

How it’s used

As a bonding slurry/bond coat and/or as a polymer modifier in repair mortar, screed, render, and patching formulations.

Selection drivers

Solids %, viscosity, film-forming profile, site temperature, mixing method, and compatibility with cement/additives.

Note: Final performance depends on substrate preparation, mix design, and curing. Validate by trial areas and site QA/QC.

Applications

Typical usage patterns. Tell us your process and constraints and we’ll align the right specification.

  • Bonding slurry (cement + SBR) for concrete-to-concrete repairs
  • Polymer-modified repair mortars and patching systems
  • Screeds and renders where improved adhesion and reduced permeability are needed
  • Cementitious overlays and toppings (project dependent)
  • General adhesion improvement in compatible cementitious mixes

Bond coat use

Used as a cementitious slurry to promote bonding between prepared substrate and repair material.

Mortar modifier use

Added to mixing water to improve cohesion, adhesion, and durability in polymer-modified repair mortars.

Where it’s common

Structural/architectural repairs, patching, overlays, and refurbishment work (compatibility dependent).

Quality & documentation

Bond coat timing

Apply repair mortar while the bonding slurry is still tacky/wet (common practice). Avoid letting the bond coat fully dry unless your method specifies otherwise.

Mix consistency

Solids % and dilution influence viscosity and workability. Align with your method statement and confirm by trial mixes.

Surface prep

Remove laitance, dust, oils, and weak layers. Roughen as required. Good prep is often the biggest driver of adhesion performance.

Curing

Cementitious systems still need appropriate curing. Protect from rapid drying, heat, and wind to reduce shrinkage cracking.

Compatibility

Confirm compatibility with other admixtures (water reducers, accelerators, fibers) and cement chemistry via trial mixes.

Storage & handling

Protect from freezing and extreme heat (grade dependent). Follow SDS for PPE, storage, and disposal guidance.

Safety note: For industrial/construction use. Follow SDS for handling, PPE, storage, and disposal. Always comply with site requirements and local regulations.

Typical specifications & formats

Values depend on grade and customer requirements. Confirm details on quotation and COA.

Indicative procurement specification (example)

This is a common procurement/QC format. Exact limits should be confirmed in your RFQ and via the supplied COA/TDS.

Parameter Typical listing (indicative) Commercial / QC note
Product Bonding Agent (SBR Latex) Specify if for bond coat, mortar modifier, or both
Form Liquid latex emulsion Confirm viscosity range for your application method
Solids content Grade dependent Request solids % and test method on TDS/COA
Packaging Drum / IBC / bulk Define net weight, palletization, storage constraints
Documentation SDS / COA (TDS as available) State required language/format and onboarding templates
Storage Protect from freezing / extreme heat (grade dependent) Confirm shelf life and storage temperature range

If your project requires specific tests (bond strength, tensile/flexural), include them in the RFQ so we can align the right grade and documentation.

Specifications may vary depending on batch, origin, and packaging selection.

FAQ

Quick answers for site, engineering, and procurement.

Start an RFQ
Is SBR latex used as a bonding coat or mixed into mortar?

Both are common. Some projects use SBR in a cement slurry as a bonding coat; others use it as a polymer modifier in the repair mortar itself. Share your method statement so we can align the right grade and viscosity profile.

What matters most for adhesion performance?

Surface preparation (sound substrate, roughness, cleanliness) and curing practices often dominate results. The SBR grade must also be compatible with your cement system and other additives.

What information helps you quote fastest?

Use case (bond coat vs. mortar modifier), solids/viscosity preference (if any), packaging, volume, destination + Incoterms, and document requirements (SDS/COA/TDS).

Does SBR improve water resistance?

In compatible cementitious systems, SBR modification can reduce water absorption and improve durability characteristics. Final performance depends on mix design and curing—validate by trials.

How should it be stored and handled?

Storage requirements vary by grade, but protection from freezing and excessive heat is commonly important. Follow the SDS for PPE and handling guidance.
