Key Properties
  • The solvent-free and low-viscosity ARADUR® 891 has very good processing properties and can be washed down with water.
  • In combination with Araldite® GY 783 It is used for bonding and joining of tiles, e.g. in baths, slaughter houses, dairies, breweries and beverage filling stations.
  • It has good resistance to inorganic acids, less good resistance to oxidizing and organic acids and moderate resistance to solvents.
  • The curing process slows down at temperatures below 20 °C. This delay can be compensated by adding small quantities of accelerator 960-1.
