Methacrylate-functionalized silanes like Dynasylan® SIVO 250 are an excellent solution for the chemical bonding of the EVA-based encapsulant films to front glass and the polycrystalline silicon solar cells layer of photovoltaic modules. Dynasylan® SIVO 250 can be grafted onto the EVA polymer chain, by easily compounding with the EVA granules and other additives within the production process of the EVA encapsulation films. By the production of the solar panel, after the lamination step of the encapsulation film, Dynasylan® SIVO 250 acts as adhesion promoter between the inorganic glass layer and the silicone solar cells layer, enhancing the electrical properties and water vapor transmission of the module.
Dynasylan® SIVO 250 can be used as monomer during resin synthesis (e.g. latex dispersions). It may partially replace other reactive monomers like acryl or methacryl-functional monomers (usually 0.5-3 %, but sometimes up to 20%). The thus incorporated silane functionality can lead to improved properties in the final application (e.g. coating or sealant) of such resins:
- Wet adhesion strength
- Chemical resistance
- Mar resistance

Dynasylan® SIVO 250 is used as adhesion promoter in application such as:
- As an additive for filled and unfilled peroxide-crosslinked elastomers (EVA).
- As a surface modifier for pigments and fillers for thermosets (unsaturated polyester, MMA), thermoplastics (polyesters and polyolefins)and elastomers.
- As an additive for casting resins (unsaturated polyester, MMA).
For primer application:
Dynasylan® SIVO 250 is applied on inorganic substrate as a pretreatment by dipping, spraying, or coating. As adhesion promoter it may be added directly to the resin matrix (additive
process). For pretreatment, the silane may be used- Neat

Technical Details & Test Data
- Reactivity Information
The alkoxy group of Dynasylan® SIVO 250 hydrolyzes in the presence of moisture (and a suitable catalyst such as acetic acid) to produce methanol and reactive silanol (Si-OH) groups which can bond to a variety of inorganic substrates. The methacryl groups can take place as a co-monomer in a radical polymerisation or interacts with the polymer. Examples of suitable inorganic substrates are glass, polycrystalline silicon, glass fibers, glass wool, mineral wool, silicic acid, quartz, sand, cristobalite, wollastonite and mica; also suitable are aluminum hydroxide, kaolin, talc, other silicate fillers, metal oxides, aluminum, stainless steel and other metals. Examples of suitable polymers include unsaturated polyester, acrylates and vinyl esters.
