Dynasylan® SIVO 560

Dynasylan® SIVO 560 is a multifunctional silane system with a high concentration of unsaturated organic groups. It can be used as coupling agent and surface modifier in various applications.

Scope of Application

Dynasylan® SIVO 560 is used as reactive coupling agent in various applications: as an additive for casting resins (unsaturated polyester, MMA), especially for the production of engineered stones as a surface modifier for pigments and fillers for thermosets (unsaturated polyester, MMA), thermoplastics (polyesters and polyolefins) and elastomers as an additive for filled, peroxide-crosslinked elastomers Dynasylan® SIVO 560 is either applied to the inorganic substrate as a pretreatment by dipping, spraying, or coating or it may be added directly to the resin matrix (additive process). For pretreatment, the silane may be used neat dissolved in an organic solvent dissolved in a mixture of organic solvent and water for partial hydrolysis In the additive process Dynasylan® SIVO 560 is mixed with the resin or polymer before or together with the filler. A prerequisite for this method is compatibility of the silane with the resin since the silane must not react prematurely with the resin.
