Easy to use and conveniently packaged, Master Bond adhesives, sealants and coatings have been developed to withstand exposure to bases. These high performance compositions offer high physical strength properties, superior electrical insulation characteristics and enhanced reliability. From processing equipment to chemical piping to storage tanks, our compounds are widely employed in the chemical industry and offer consistent dependability.
Epoxy Compounds Offer Superior Protection Against Bases
Grades are available that feature resistance to selected bases such as:
- Sodium hydroxide
- Potassium hydroxide
- Potassium chloride
