Technologically advanced adhesives, sealants and coatings offer unmatched resistance to acids. They are presently employed in applications ranging from design and production to repair, maintenance and field service.
These liquid/paste compounds safeguard critical parts/components used in industrial equipment, machinery, instruments from splash, vapor, immersion exposures. They provide high mechanical strength properties between multiple substrates including pretreated metals, plastics, ceramic, glass, protect against corrosion and can be automatically dispensed in high volume production applications. They are frequently applied manually with a brush, roller, sprayer. Select grades feature outstanding performance under a combination of high stress and elevated temperatures. Heat cured or post cured products increase crosslink density and are recommended for extreme chemical environments. Type of substrates being joined, shape of substrates, desired bond line thickness, speed of cure are important considerations when selecting the most suitable adhesive. Testing should be done prior to use to replicate actual service conditions.
Durable, long lasting two component epoxy systems have proven particularly effective in ensuring cost effective, consistent, reliable, repeatable usage in protection for pumps, valves, fans, pipes, tanks, metal processing equipment, earth moving vehicles, fork lifts, power generation and mining equipment. Additionally special products defend against hostile chemicals and high impact, abrasion, thermal cycling, wear. They also exhibit outstanding electrical insulation characteristics.
Specially Formulated Polymer Systems
Specific grades offer outstanding resistance to various concentrations of selected acids such as:
- Sulfuric acid
- Hydrofluoric acid
- Nitric acid
- Chromic acid
- Phosphoric acid
Master Bond's database of chemical immersion tests extends up to 10 years.
