Fitherm AG – Glue

Product Description

Fitherm® AG is a non-combustable glue (A1) based on water glass. Fitherm AG is developed for bonding different parts or filling small gaps or cavities in fire protection and foundry industry. Fitherm® AG could be used to bond, for example, gipsum board, cement fibre board, calcium silicate board etc. or with steel, concrete, masonry etc. Fitherm® AG cures mainly by means of dehydration, therefore, is not applicable if the bonded materials do not allow water to escape. Fitherm AG is not resistant to humidity and recommended to apply only in interior and dry areas. Fitherm AG possesses a high thermal stability up to 800°C. In case of fire Fitherm AG does not emit any combustible and harmful gases.
