I wouldn't assume that. Based on what's written about 3-AEPS in
histological literature, my guess is that that particular silane
doesn't help adhesion of gelatin at an ordinary coating pH. (That
silane is sometimes used to mount/adhere specimen on microscope
slides. People around me use chrome gelatin instead, partly because
the specimen is often buffered at pH of 7.4.)
