Alklear, our premium high-alumina bonded solution is mainly dedicated to forehearth glass contact channel blocks. Its excellent behaviour in contact with sodalime glass drastically reduces risk of glass defect.
The outstanding thermal shock resistance and ability to accomodate fast heat up makes it the prefered option for installation in hot condition.
