Scope Definition

Epoxy resin for nuclear power plant reinforcement refers to high-performance chemical anchoring adhesives engineered to meet the stringent structural, corrosion-resistance, and long-term durability demands of nuclear-grade infrastructure. This technical reference covers the MT-500 Injectable Rebar Adhesive, developed by Nanjing Mankate Science & Technology Co., Ltd. (brand: NJMKT/Mankate), a high-tech enterprise founded in 2004 and headquartered in Gulou District, Nanjing, China. The product is formulated to serve rebar and threaded rod anchoring applications in concrete and granite substrates, with documented deployment in nuclear-grade safety environments such as the Tianwan Nuclear Power Plant. All specifications referenced below are drawn from verified product documentation and are strictly compliant with GB 50367-2013 (Code for Design of Strengthening Concrete Structure) and GB 50728-2011 (Technical Code for Safety Appraisal of Engineering Structural Strengthening Materials), the two governing national standards for structural reinforcement materials in China.

Core Requirements Overview

Reinforcement adhesives destined for nuclear power and other critical-infrastructure applications must satisfy a hierarchy of requirements before qualifying as epoxy resin for nuclear power plant reinforcement:

1. Material Composition — The adhesive must be based on modified epoxy resin formulation technology, ensuring chemical stability under sustained structural loading.

2. Design Verification — Anchoring performance must be validated for tensile strength, elastic modulus, and elongation through advanced laboratory testing protocols.

3. Detailing & Installation — Application procedures must account for curing behavior, substrate moisture conditions (dry, humid, or underwater), and ambient temperature variability typical of power plant environments.

4. Regulatory Compliance — Products must be certified under recognized international frameworks, including the European Technical Assessment (ETA), in addition to domestic GB standards.

The MT-500 Injectable Rebar Adhesive satisfies each of these tiers, positioned by Mankate as a premium chemical anchoring solution for rebar and threaded rod systems in concrete and granite, verified for a 100-year service life by ETA assessment.

Technical Specifications

The following measurable parameters define the technical envelope of MT-500 as an epoxy resin for nuclear power plant reinforcement:

 

 

· Service Life: 100 years, ETA-verified durability rating.

· Operating Temperature Range: -40°C to +160°C, supporting extreme environment adaptability required in containment and auxiliary structures.

· Water Absorption: As low as 0.02%, enabling application on dry, humid, and underwater substrates.

· Seismic Rating: C2 classification, indicating high stability under vibration and seismic loading conditions.

· Chemical Resistance: Acid and alkali resistant, suitable for harsh tunnel and containment-adjacent environments.

· Curing Time: Load-bearing state achieved within 1.5–2 hours at room temperature, minimizing project downtime.

· Environmental Compliance: RoHS compliant, VOC-free, and non-toxic — relevant for occupancy-sensitive nuclear facility zones.

· Governing Standards: GB 50367-2013 and GB 50728-2011, plus European Technical Assessment (ETA) certification.

Application Context

Nuclear power infrastructure imposes among the most rigorous structural anchoring requirements in civil engineering, given the criticality of long-term seismic performance, corrosion resistance, and material traceability. Nanjing Mankate has supplied the MT-500 formulation specifically for rebar anchoring adhesive applications at the Tianwan Nuclear Power Plant, addressing nuclear-grade safety requirements. This deployment sits within a broader portfolio of over 50,000 supported engineering projects globally, spanning rail transit, bridge infrastructure, marine engineering, and municipal construction. The company’s technical capability is underpinned by 19+ international certification patents, ISO 9001, ISO 14001, and ISO 45001 management system certifications, and CE marking — establishing a compliance foundation consistent with nuclear-sector procurement expectations.

Reference Value Statement

For engineers, procurement specialists, and structural safety appraisers evaluating epoxy resin for nuclear power plant reinforcement, the MT-500 Injectable Rebar Adhesive offers a documented, standards-compliant reference point: ETA-certified 100-year durability, GB 50367-2013/GB 50728-2011 conformance, and field-validated performance in nuclear-grade installations. Products are further backed by Ping An Insurance coverage and a 24-hour technical support hotline, providing an additional layer of assurance for safety-critical procurement decisions. This combination of quantified technical specifications and verified project history positions the standard as a practical benchmark for evaluating chemical anchoring adhesives in nuclear power and comparably demanding infrastructure sectors.
