Epoxy silane

Waterborne epoxy silane is A kind of nanometer zinc rich epoxy silane coating, with two components, its formula is characterized by: with all components is 100%, the weight of the following for each component weight ratio: A component: 800 ~ 1000 mesh nanometer zinc powder 65% ~ 80%, the emulsion type epoxy resin 8% ~ 25%, 0.1% ~ 5% ethanol, deionization water 0.5% ~ 5%, thickener 0.1% ~ 1%, the heavy dose of 0.1% ~ 3%;B component: silane portfolio: [double a silicon alkyl amino silane, vinyl silane] 1.5% ~ 5%, and the combination of these two kinds of silane distribution ratio between 0.15 ~ 0.30, and 3% ~ 8% curing agent.
Study found that the epoxy silane after pre emulsion can be compatible with aqueous polyurethane, after modification of aqueous system can be stable for a long time and not gel, effective storage period more than 3 months.With the increase of dosage of epoxy silane, gradually increased the tensile strength of the coating and extension first to continue to fall, after a slight increase, bibulous rate dropped significantly, to improve the bonding strength obviously.
