DOWSIL™ 732, the essential acetic silicone sealant


DOWSIL™ 732, when multipurpose means performance


A bit of theory …


DOWSIL™ 732 is an acetic silicone. As a result, it releases a small amount of acetic acid (characteristic vinegar smell) during its curing, which can cause problems on metals sensitive to corrosion (raw steel, aluminum, copper…). Therefore, its use is not recommended on metals and is not recommended near electronic boards or components.
