206 Selection of Adhesion Promoters for Different

9.24 ROOFING

The following adhesion promoters are suggested for the use in the roofing membranes:
Chartwell B-505.1, B-505.6, B-515.1/2H, B-515.71W, B-516.5, and C-515.71/1.5H. They
contain silanes having the following functionalities: amino, diamino, and mercapto.
The elastomeric roof coatings were made from emulsion copolymers containing
aminosilane (aminoethylaminopropyltrimethoxysilane) which gave excellent wet adhe-
1
sion to the weathered substrates, especially the weathered thermoplastic polyolefin.
Adhesion promoter monomers such as hydrolyzable silane functional (meth)acry-
lates, such as (meth)acryloyloxypropyltrialkoxysilanes, and ureido(meth)acrylates have
been included in the infrared reflective clear coating compositions for elastomeric wall
2
and roof coatings.
