8.24 POLYVINYLBUTYRAL

Dynasylan SIVO 210 & 214 are the commercial products suggested for adhesion promo-
tion of polyvinylbutyral.
The use of an adhesion promoter (3-aminopropyltriethoxysilane) for glass beads dis-
persed in polyvinylbutyral increased the maximum local stress required to cause debond-
ing but had no effect on the interparticle stress fields so the same trends, at higher applied
1
stress, were observed.
An adhesion promoter in the rubber composition containing polyvinylbutyral pro-
2
vides both excellent rubber-to-metal bonding and improved damping. The suitable adhe-
sion promoters include zinc dimethacrylate (Saret 634) and polybutadiene resin
2
functionalized with maleic anhydride (Ricobond 1756HS).
A jet ink composition includes ethanol, a binder (polyvinylbutyral, 2-15 wt%), a
3
conductive agent, and an adhesion promoter (0.5 wt%). A suitable adhesion promoter is a
silane, such as β-(3,4-epoxycyclohexyl)ethyltrimethoxysilane or γ-glycidoxypropylt-
3
rimethoxysilane.
