Performance properties can be adjusted to meet specific application requirements. Master Bond’s extensive product line includes compounds that comply with industry certifications.

Adhesives for mining equipment

Master Bond’s coatings offer protection against hostile conditions encountered in the mining process. Specific grades feature high hardness, which prevents degradation from severe chemical attacks, including splash, spills, immersion, friction, wear and a combination of impact and abrasion.

Corrosion mitigation properties on metallic substrates meet high standards to ensure the structural integrity of mining equipment and long-term reliable serviceability.

Master Bond’s metal-filled epoxy and elastomeric compounds have been used in such assemblies. Room temperature-curing, two-component epoxies have also been used in many sealing and gap filling applications.

Aluminium-filled compositions are employed for their good void filling capability, dimensional stability, low shrinkage and outstanding physical strength characteristics.

Industrial adhesive certifications

Master Bond products are formulated to the highest quality standards. Compliance testing has been conducted by American government authorities and established independent testing laboratories.

Our extensive product line includes a variety of compounds that pass stringent testing requirements. A partial list of these specifications is listed below:

• Nasa low outgassing
