Abstract
A coating composition for glass fibres intended for use as reinforcement in cementitious products is disclosed, which contains at least one monocyclic or polycyclic aromatic compound having at least three hydroxyl groups on the aromatic ring or (in a polycyclic compound) on at least one of the aromatic rings, together with at least one partially-cured A-stage phenolformaldehyde resin of the water-dilutable resole type.
Claims14
Glass fibres for use as reinforcement in inorganic cementitious products, said fibres being coating with a composition containing at least one monocyclic or polycyclic aromatic compound which has at least three hydroxyl groups on the aromatic ring or, in a polycyclic compound, on at least one of the aromatic rings, and at least one partially-cured water-dilutable A-stage phenol-formaldehyde resole resin.
Inorganic cementitious products reinforced with coated glass fibres according to claim I.
A method of coating glass fibres to reduce their rate of deterioration when incorporated in inorganic cementitious products, comprising applying to the glass fibres a coating composition containing at least one monocyclic or polycyclic aromatic compound which has at least three hydroxyl groups on the aromatic ring, or in a polycylic compound, on at least one of the aromatic rings, and at least one partially-cured water-dilutable A-stage phenol-formaldehyde resole resin.
A method of forming a glass fibre reinforced inorganic cementitious product, wherein glass fibres are coated with a composition containing at least one monocyclic or polycyclic aromatic compound which has at least three hydroxyl groups on the aromatic ring or, in a polycyclic compound, on at least one of the aromatic rigs, and at least one partially-cured water-dilutable A-stage phenol-formaldehyde resole resin, and the glass fibres are subsequently incorporated into a cemetitious matrix.
