Application Process

Filoform MD+ sealant The Filoform duct sealing system FiloSeal+ uses MD+ sealant which is easily applied from a standard skeleton gun. The high quality, one component, flexible sealant “MD+” is based on a silicon compound that cures with air (Humidity).

After application and full curing the thixotropic MD+ forms a plastic elastomer mass with special qualities effectively sealing and bonding, while providing a high level of durability.

FiloSeal+ is very easy to apply regardless of the type of cable scenario in the cable ducts as it uses a uniquely shaped foam piece which positions neatly around the cables or pipes in the duct.

filoform tri-flexible foamThe unique design of the tri-flexible foam makes positioning and separation of the cables very simple while also providing a backing for the MD+ to be applied on.

This seal is easily installed in vertical scenarios while providing the added security of ensuring no loss of components down the duct.

FiloSeal+ is suitable for sealing several cables or pipes contained in one duct and also allows re-entry of the seal to add or remove cables or pipes as required.
