Abstract

The comparison of MagPro®150 magnesium oxide (MgO), obtained by calcination of brucite mineral, with synthetic analogues was carried
out in the composition of cold-setting solution adhesives (A) based on Baypren 330. Two technologies of adhesive production were tested –
simultaneous introduction of all ingredients and preliminary mixing of phenol formaldehyde resin with MgO. It has been shown that A
containing MagPro®150 natural based MgO have the same level of adhesive properties, pot life and color as adhesives with synthetic grades
of MgO. To obtain adhesives A with improved adhesive characteristics, it is recommended to pre-mix MgO and phenol formaldehyde resin with
a small amount of water to form a chelate complex.
