Bond Organic and Inorganic
Organics such as thermoplastic resins and epoxies, and inorganics such as
glass fiber and mineral fillers, may not naturally bond. Attempting to combine
them can negatively impact the mechanical properties of the finished compound.
A compatibilizer, or coupling agent, strongly bonds organic and inorganic
materials together by chemically reacting to both of them.
Advanced compatibilizers from Dow Corning can create compounds with
better performance than either material can deliver by itself. For example, our
silane solutions can create compounds of epoxies and glass fiber with higher
heat deflection temperatures (HDTs) than the organic material alone.
Compared to commodity silane compatibilizers, our technology provides
stronger bonding and adds improved performance to the finished material-all at
very low loadings.
Solving Your Application
Dow Corning compatibilizers are ideal for compounding and for glass
fiber treatment. They raise the HDT of glass fiber-reinforced PP by 10°C to
15°C. In automotive under-hood components and appliance applications, these PP
compounds can replace glass fiber-reinforced PA 6 to reduce weight and improve
cost-effectiveness. In printed circuit board (PCB) manufacturing, our Dow
Corning® Z-6132 Silane series delivers excellent thermal stability and
improves anti-CAF (conductive anodic filament) performance, which enables
production of thinner PCBs for smart devices.
Our compatibilizer portfolio offers you these benefits:
Improved adhesion between incompatible organic and inorganic
Higher performance of the final material
New opportunities for innovative compounds
Value-add to pre-treatment of glass fiber
Cost control with low loadings of 1.0% to 1.3%
