Description
A modified nylon developed by DuPont and ICI about 1940. Soluble nylon is Nylon resin that has been treated with Formaldehyde to produce an unstable alkoxy substituted material. One commercial product, Calaton (n-methoxymethyl nylon), is prepared from Nylon 6,6. The freshly prepared alkoxy substituted nylon is soluble in alcohols. However, when it is painted as a film, soluble nylon can hydrolyze, especially in the presence of acids, to produce a stiff, insoluble film. Soluble nylon was used in the mid-20th century as an adhesive, coating, and sizing agent to add strength to wet paper and consolidate friable pigments. It is not recommended for any type of current conservation use.
