Sicador®-32 High Mode (A-B)

In renovation and construction expansion projects, contractors face a decisive technical challenge: how to ensure a strong structural bond between old and new concrete that can bear loads and pressures without separation or cracking? Sikadur®-32 Hi-Mod is a two-component epoxy bonding agent that solves this dilemma efficiently, proven in thousands of construction projects in Saudi Arabia and the Gulf countries. This Swiss product provides exceptional adhesion strength reaching 15 MPa, with high resistance to heat and humidity, making it the first choice for engineers in infrastructure and government building projects. What is Sikadur®-32? Composition and technical properties Sikadur®-32 Hi-Mod is a liquid structural adhesive based on high-viscosity epoxy resins, specifically designed for structural bonding applications between concrete and concrete, or concrete and metals. It consists of two components (Component A + Component B) mixed in specified ratios to form a solvent-free bonding material with superior mechanical properties. Chemical composition and technical specifications Sikadur®-32 relies on a chemical reaction between epoxy resins (Component A) and a modified hardener (Component B), according to the following ratios: Component A (resin): 2.82 kg - light gray color Component B (hardener): 4.25 kg - dark gray color Total package weight: 7.07 kg Mixing ratio: 2:3 volumetrically (A:B) Physical properties after curing (23°C): Tensile strength: 15-18 MPa (ASTM D638) Compressive strength: 80-90 MPa (ASTM D695) Elastic modulus: 6000-7000 MPa Shear bond strength: >4 MPa Operating temperature: from +10°C to +35°C Heat resistance after curing: up to +50°C Technical features that make Sikadur®-32 the preferred choice 1. High structural bonding strength The product achieves shear bond strength exceeding 4 MPa, meaning failure will occur in the concrete itself before the epoxy layer — this is the true indicator of successful structural bonding. This value exceeds most international standards like ASTM C881 Types I and II. 2. Effective on damp surfaces Unlike traditional epoxy materials that require completely dry surfaces, Sikadur®-32 works efficiently on concrete with surface moisture (up to 6% by weight). This feature is critical in Saudi work sites where morning condensation or trapped moisture inside old concrete is common. 3. Excellent resistance to harsh Gulf conditions Developed to withstand: High temperatures: maintains mechanical properties up to 50°C High humidity: unaffected by atmospheric moisture during and after curing Salinity: resistant to salt environments in coastal areas (Dammam, Jeddah, Yanbu) UV rays: does not degrade under direct sunlight 4. Thixotropic properties The product has controllable viscosity — it flows under pressure (during roller or brush application) but does not drip or sag from vertical or overhead surfaces. This makes it ideal for wall and ceiling bonding applications. 5. Wide application range Works efficiently in various site conditions: Low temperatures: can be applied from +10°C Horizontal, vertical, and overhead uses: full control over flow Multiple thicknesses: from 1 mm to 5 mm depending on application Uses of Sikadur®-32 in construction projects Bonding new slabs and concrete elements to old ones The most common application is creating an adhesion layer between existing concrete and new concrete, such as: Expansion of slabs: adding new wings to existing buildings Strengthening ceilings: pouring a strengthening layer (Topping Layer) over existing slabs Bonding additional columns and beams: in rehabilitation projects Repairing bridges and overpasses: bonding repair layers to original concrete Rebar doweling Used as a bonding layer before installing dowel bars in drilled holes, providing: Full adhesion between steel surface and surrounding concrete Effective transfer of tension and shear forces Prevents corrosion thanks to the protective layer Engineering note: For high-load dowel applications, it is recommended to use Sikadur®-32 with Sikadur®-31 epoxy injection mortar or chemical anchoring systems. Concrete bonding Specialized bonding includes: Fixing steel or aluminum sheets to concrete Bonding equipment and machinery bases Attaching external strengthening systems Installing metal barriers and railings Repair and crack fixing Acts as a preparatory layer before applying epoxy or cementitious repair materials, ensuring: Strong bonding of repair mortar to original concrete Prevents separation of repair layers under loads Extends repair lifespan Application guidelines 1. Surface preparation The quality of bonding depends 70% on proper surface preparation: Mandatory steps: Remove weak materials: break and remove delaminated or deteriorated concrete Mechanical cleaning: use sandblasting or water jetting at 1500-2000 PSI Remove oils and grease: wash with alkaline cleaners if needed Expose aggregate: concrete surface should be rough with visible aggregate Dry or damp: depending on application — surface can be moist but free of free-standing water Readiness test: surface is ready when: No loose dust or dirt Concrete is cohesive and not crumbling No surface puddles 2. Mixing procedure Precise ratios are critical: Pour entire Component B into Component A Mix for 3-4 minutes using a slow electric mixer (300-400 RPM) Scrape sides and bottom of the container for a uniform mixture Uniform color (medium gray without streaks) indicates complete mixing Pot life: At 10°C — 60 minutes At 20°C — 40 minutes At 30°C — 25 minutes At 35°C — 20 minutes 3. Application method Brushing: use a stiff brush or short-haired roller Apply a uniform layer 1-2 mm thick Ensure complete coverage without dry spots Consumption rate: 1.5-2.0 kg/m² depending on surface roughness Critical timing: new concrete must be poured within 30-60 minutes of epoxy application (depending on temperature) while the surface remains tacky. If the surface dries: reapply a new layer or roughen before pouring. 4. Pouring and curing Pour new concrete directly over the tacky epoxy layer Avoid strong shocks that could separate layers Cure the concrete using standard methods (water spray or plastic covers) Full curing time: 7 days at 23°C Why choose Ibtidad Al-Omran to buy Sikadur®-32?

Frequently asked questions about Sikadur®-32 Can Sikadur®-32 be used on damp concrete? Yes, one of its key features is working on damp surfaces with moisture up to 6% by weight. However, free-standing water or puddles on the surface should not be present — only moisture trapped inside the pores. What is the difference between Sikadur®-32 and Sikadur®-31? Sikadur®-32 is a liquid bonding agent applied as a thin layer to bond concrete, while Sikadur®-31 is a thicker epoxy mortar used for repairs and filling cracks. They can be used together: Sikadur®-32 as a bonding layer, then Sikadur®-31 for repair. How much area does a 7.07 kg pack cover? Approximately 25-35 m² depending on surface roughness, with a consumption rate of 1.5-2.0 kg/m². Very rough surfaces consume more. Does it withstand high summer temperatures in Saudi Arabia? Yes, after full curing, it withstands up to 50°C without losing mechanical properties. During application, it is recommended to work during cooler periods (early morning or evening) to extend pot life. How long does Sikadur®-32 take to dry? Initial curing occurs within 6-8 hours at 23°C, but full curing takes 7 days. Light walking on the surface can be done after 24 hours, but full loads require complete curing. Is it suitable for installing chemical dowels and nails? It is used as a bonding layer with anchoring systems, but for high-load applications, specialized systems like Sikadur®-31 CF or chemical injection resins are preferred.
