Zusammenfassung: | Impregnated sheets made from fibrous textiles containing 10-30 wt.% of a mixture of unsaturated polyester and a unsaturated polymerisable monomer of boiling point more than 50 degrees C and a photoinitiator in proportion 0.01-4 wt.% of the polyester/monomer. The product is crosslinked photochemically. The impregnating solution has unlimited pot life, and very short gelation time. Polymerisation can be interrupted if required. |
