Application Process

Filoform FiloSeal+HD Duct Seal

Filoform FiloSeal+HD (280010, 280020, 280030, 280040, 280050, 280060) is an engineered solution that provides a strong support system using the hexagonal tubes which builds up like a honeycomb structure.

The Filoform duct sealing system FiloSeal+HD uses our 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.

Very easy to apply regardless of the type of cable scenario in the cable ducts as it uses strong, but flexible hexagonal tubes to support the cable and provide a strong backing for the seal

The unique design of the hexagonal tubes makes positioning and separation of the cables very simple while also providing a strong backing for the MD+ to be applied on.
