Epoxy Metal Putty for Concrete and Metal Repair: UAE Contractor Guide

Structural repairs on UAE infrastructure — bridges, industrial facilities, desalination plants, and high-rise concrete — require repair compounds that perform under thermal cycling from 10°C to 55°C, resist salt-laden coastal air, and meet project engineer approval without lengthy re-specification. Epoxy metal putty is the go-to solution when standard cementitious repair mortars lack the bond strength or chemical resistance for the application.

What Is Epoxy Metal Putty?

Epoxy metal putty is a two-component (Part A resin + Part B hardener) room-temperature-curing compound formulated to bond to concrete, steel, cast iron, aluminium, and most structural substrates. Unlike welding compounds, it requires no hot-work permit — critical for UAE petrochemical and occupied-building applications.

KalciteBond Epoxy Metal Putty is independently tested by CCCS (China Classification Society Certification Co., CNAS L24234, ILAC-MRA accredited):

  • Tensile shear strength: 22.4 MPa (Report ZR268571012, GB/T 7124-2008, valid until 2027-02-03)
  • Surface dry: 29 minutes at 25°C
  • Full cure: 8.35 hours
  • Water resistance 72h: 93.7% strength retained (GB/T 1733-1993)
  • Oil resistance 72h: 94.6% strength retained
  • Service temperature: -20°C to 80°C
  • Shore D hardness: 78 at 23°C

All figures above are third-party certified. No internal or estimated data.

Common UAE Applications

Concrete Crack Repair

Suitable for cracks 0.2–5 mm width in structural concrete: bridge decks, car park slabs, sea-front promenades. The compound’s 93.7% water resistance retention after 72h immersion (certified) means it performs in Dubai coastal and below-grade environments.

Bridge Bearing Grouting

High compressive strength (>60 MPa per GB/T 50728) and 22.4 MPa shear bond make KalciteBond suitable for bridge bearing plate grouting on UAE road infrastructure projects. CCCS/CNAS certification is accepted by most UAE municipal engineers.

Industrial Metal Repair

Repair of casting defects in pump housings, valve bodies, and industrial equipment without disassembly or hot-work. Shore D 78 after cure allows machining. For detailed guidance see our Casting Defect Repair landing page.

Pipe Repair

Cold-applied pipe repair without hot-work permit. Fast 29-minute surface dry allows rapid return to service. Full guidance at our Pipe Repair Epoxy page.

Surface Preparation for UAE Conditions

Bond strength is substrate-preparation-dependent. For 22.4 MPa certified performance:

  1. Remove all contamination (oil, grease, salts). In coastal UAE environments, chloride levels must be below 0.01% on the repair surface — KalciteBond’s chloride ion resistance is <0.01%.
  2. Mechanical preparation: disc grind concrete to CSP 3 minimum; sandblast or disc-grind steel to Sa 2.5 / St 3.
  3. Substrate moisture: apply on surfaces with ≤10% moisture content (product handles damp substrates up to 10%).
  4. Ambient temperature: 5–40°C. In UAE summer, schedule application before 09:00 or after 17:00.

Shipping and Documentation for UAE Import

KalciteBond Epoxy Metal Putty is GHS unclassified (non-hazardous goods) and is not a restricted article under IATA or IMDG regulations. Eight heavy metals are N.D. (not detected) per REACH/RoHS testing. This simplifies UAE customs clearance and project site permit requirements.

Available documentation: CCCS/CNAS test report, MSDS (English + Arabic), COA, TDS, REACH/RoHS compliance statement. All provided within 24 hours of inquiry.

FOB lead time: 20 days from Tianjin. View full product data and request pricing at our Epoxy Metal Putty product page or contact info@kalcite.com.

Frequently Asked Questions

Is the 22.4 MPa strength figure independently certified or self-reported?

It is independently certified. CCCS (China Classification Society Certification Co.) is accredited by CNAS (China National Accreditation Service, Laboratory No. L24234) under the ILAC-MRA mutual recognition arrangement. Test Report ZR268571012 is valid until 2027-02-03 and available for download.

Can KalciteBond be used on UAE bridge projects requiring project engineer approval?

Yes. The CCCS/CNAS ILAC-MRA accredited test report is the standard submission for UAE structural repair material approval. KALCITE also provides a product datasheet formatted for UAE municipality engineer review on request.

What is the minimum order for UAE contractors?

KALCITE supplies project-specific quantities and distributor stock orders. Contact info@kalcite.com with your project scope (linear metres of crack, number of repair points, or kg estimate) for a project quote within 24 hours.
