Canvas treated with rubber

I am a textile conservator researching the materials and
manufacturing methods of 19th century painted banners in the UK.
Silk banners made by Tutill and Co., from 1861 were treated with a
thin rubber solution prior to painting in order to make them,
according to Tutill's contemporary accounts, more flexible and
durable. The artist suppliers Winsor and Newton sold canvas
similarly treated with rubber between 1840-49.  Does anyone know of
the existence of paintings which have a rubber treated canvas and
has the rubber seemingly affected the condition and longevity of the
paintings in any manner?  I suspect that the rubber on painted
banners is now rendering them more inflexible and brittle than they
otherwise would be.
