Bac2 (Southampton, U.K.) has introduced a latent acid catalyst, CSR10, that can be added to highly reactive pre-polymeric resins to enable them to be stored for at least three months prior to controlled polymerization at 120°C/248°F. This catalyst is said to be particularly useful where polymeric pre-mix production is not carried out close to molding operations as it enables safer transportation and storage of the bulk materials and reduces handling costs. Pre-polymeric resins catalyzed by acids include phenol-formaldehyde resoles, furfuryl alcohol resins and amino-formaldehyde resins. CSR10 has been used to harness the reactivity of pre-polymers to reduce materials handling and processing costs, and enable the use of a wider range of pre-polymers in industrial applications.
