Brief Introduction

AMR Sealant

AMR Sealant is a water based high temperature resistant fireclay using high alumina fiber as the main raw material. It is used in the installation, reparation, and sealing of chutes, joints, pin-boards and nozzles. It is an air hardening material featured with fast drying, high strength and good corrosion resistance. 

Main characteristics:

  • Nonwetting to molten aluminum, copper, magnesium, zinc and their alloy. 
  • Convenient construction, fine surface quality, no adhesion.
  • Good adhesion ability to all refractories.
  • Fast drying and no shrinkage during high temperature service. 
  • Water based, no volatilization of hazardous materials during service, clean and environmental friendly.
  • Long shelf life and good chemical stability.
