Caulk

22 CaulkArrow icon

22 CAULK is ideal for filling joints and cracks in refractory linings. Job site mixing is not needed. Just snip-off the tip of the ready-to-use caulking tube and apply the moist material using a hand or air powered caulking gun. Heat loss through joints and cracks will be reduced. Fine particles will not accumulate in those openings, preventing further damage to the lining. The surface of 22 CAULK will harden when exposed to air.

Adaphos 85 DipArrow icon

ADAPHOS 85 is a wet ready-mixed high alumina bonding mortar with a chemical bonding system. With the unique bonding system, a high bonding strength is developed at lower temperatures (300-600°F) and the high bonding strength continues until a ceramic bonding occurs. ADAPHOS 85 is primarily used to lay up high alumina brick in ladles and is available in both trowelling and dipping consistencies. It is used in areas where severe service conditions require increased refractoriness to corrosion/erosion from slags.
