Impact-resistant Wear-resistant Ceramic AB Adhesive

Updated: 2026-07-22

Overview

Impact-Resistant Wear-Resistant Ceramic AB Adhesive is a specialized industrial epoxy formulation designed for bonding ceramic components in high-stress environments. As a two-component system (resin and hardener), it combines exceptional mechanical properties with chemical resistance, making it particularly valuable in industries where equipment faces severe abrasion and impact forces. The adhesive is engineered to maintain bond integrity under continuous vibration and mechanical shock, outperforming conventional adhesives in mining, mineral processing, and power generation applications. Its development responds to the growing need for durable repair solutions for ceramic-lined chutes, hoppers, and pipelines that handle abrasive materials.

Physical and Chemical Properties

This adhesive system exhibits a unique combination of high compressive strength (typically 80-100 MPa) and elasticity modulus that absorbs impact energy without cracking. The cured adhesive demonstrates Shore D hardness of 85-90, providing excellent resistance to particle erosion. Its thermal expansion coefficient is carefully matched to ceramics (approximately 5-7×10⁻⁶/°C) to minimize stress at bonded interfaces. Chemically, the formulation resists dilute acids, alkalis, and solvents commonly encountered in industrial environments. The working viscosity ranges from 15,000-30,000 cP (mixed), allowing good wetting of ceramic surfaces while preventing sagging on vertical applications. Pot life varies from 30-90 minutes at 25°C depending on specific product grades.

Main Applications

Primary applications focus on industries handling abrasive materials: 1) Mining - bonding alumina ceramic liners in transfer chutes, trommel screens, and cyclone feed launder; 2) Power generation - securing ceramic tiles in fly ash handling systems and coal pulverizer components; 3) Cement production - maintaining wear plates in clinker coolers and raw mill ductwork. The adhesive is also specified for repair applications, effectively bonding new ceramic segments to existing installations without requiring complete system replacement. In material processing plants, it serves as a reliable solution for ceramic-lined elbows and diverter valves subject to both abrasion and impact from conveyed materials.

Safety and Storage

Proper handling requires separating components until use and mixing in recommended ratios (commonly 1:1 or 2:1 by volume). Uncured components may contain epoxy resins and amine hardeners that can cause skin sensitization - nitrile gloves and protective eyewear are essential. Work areas should have adequate ventilation to prevent inhalation of vapors during application. Storage stability is maximized when kept in original sealed containers between 5-25°C. Part A (resin) should be protected from moisture absorption, while Part B (hardener) requires protection from atmospheric carbon dioxide. Frozen storage is not recommended as it may cause component separation or crystallization. Shelf life indicators should be strictly observed.

B2B Procurement Guide

Industrial buyers should prioritize suppliers with technical support capabilities and industry-specific formulation experience. Key procurement considerations include: 1) Certifications - verify compliance with ISO 9001 and relevant industry standards; 2) Technical documentation - request complete product datasheets with tested mechanical properties; 3) Batch consistency - established manufacturers should provide quality control certificates. For large-scale projects, consider requesting sample quantities for field testing under actual operating conditions. Evaluate application parameters such as required open time, minimum curing temperature, and post-cure schedules. Bulk purchasing (typically 20kg+ quantities) often provides cost advantages, but verify storage capabilities and projected usage rates to prevent material expiration.
