Mouldables and patching compounds


ProMixSealer® patching compounds are specially designed to repair hot and cold launder systems, to securely bond refractory launder joint segments or for expansion joint filling. They are in-house developed and manufactured and are made from high temperature non-ceramic, low bio-persistent fibers.

ProMixSealer® is a refractory fiber based mouldable composition for use in direct contact with molten aluminium. All our ProMixSealer® products have extremely low thermal shrinkage abilities and exhibit excellent adhesion. Next to this they have excellent insulation properties, high strength and superior non-wetting characteristics.
