Purpose & Audience

ASI 502 is a black, food-grade RTV silicone sealant in a 2.8 oz squeeze tube. It suits maintenance staff, fabricators and DIYers who need a flexible, non-slump bond on vertical or overhead surfaces.

Deciding Specification

The product carries FDA Regulation 175.105 clearance for incidental food contact and is UL and NSF recognised. That regulatory status is the single factor that determines whether the sealant meets your compliance requirements.

Thermals, Noise & Power

Curing occurs at room temperature with no equipment, so there is no power draw or acoustic output. The cured rubber withstands continuous service from -70 to +400 degrees F and can be applied to substrates between -18 and +50 degrees C.
