Description

XIAMETER OFS-6011 Silane is a reactive chemical containing an aminopropyl organic group and a triethoxysilyl inorganic group. Chemically, XIAMETER OFS-6011 Silane is designated gammaaminopropyltriethoxysilane (fw 221.4). Possessing both organic and inorganic reactivity, XIAMETER OFS-6011 Silane can react with organic resins and elastomers as well as with the surface of inorganic materials such as fiberglass and silica.

XIAMETER OFS-6011 Silane is particularly recommended for fiberglass-reinforced phenolic, melamine, and epoxy thermoset composites, either as a fiberglass finish or as a resinous additive. Data suggests that this silane can also improve the performance of these types of themoset resins when used as mineral binders in foundry and abrasive composite applications. When used as a resin additive, generally the silane is added at a level of 1 percent based on the weight of the resin solids. For each specific application, the optimum level of additive should be determined by testing several concentrations. When used as an additive to epoxy coating, XIAMETER OFS-6011 Silane improves adhesion of the coating, particularly in very humid environments.

XIAMETER OFS-6011 Silane has also been found to be an effective coupling agent for clay-reinforced elastomers such as natural and nitrile rubber.

XIAMETER OFS-6011 Silane will also improve the adhesion of many coatings (urethanes, epoxies, phenolics, and others) to glass and metal surfaces. Best performance is realized when XIAMETER OFS-6011 Silane is used as a primer, although addition to the coating can also give benefits.
