Emseal DSF System
NSF-61 compliant joint system for food production and preparation environments
An NSF compliant joint sealant, DSF System features a silicone-bellows sealing surface and a precompressed, impregnated foam backing. DSF provides a lasting solution to joint sealing applications and will not pose a contamination risk to liquids or solids which may be ingested.
The silicone coating is compliant to NSF/ANSI Standard 61 for contact with potable drinking water. It is also in compliance with FDA Regulation CFR 177.2600 for indirect contact with food.
The system is comprised of precompressed, silicone-and-impregnated-foam hybrid installed into field-applied epoxy adhesive on the joint faces with the silicone bellows locked to the joint faces with a silicone sealant band.
