Ancillary Components of the Cosmofin System:
COSMOFINSTEEL – 24 gge galvanised steel with membrane factory bonded to one side. Five standard profiles shapes are always available in stock and specials are made to order.
COSMOFIN LIQUID – Used to seal laps on cut sheets to close reinforcement ends. Package size: 1L tins.
TK 400 STRIP BONDING ADHESIVE -The recommended adhesive for strip bonding of Cosmofin LLV to most substrates where adhering is required. TK 400 can be installed over existing membranes, damp substrates and is applied using 60cm Lance Applicating Gun.
COSMOFIN CORNERS – Preformed internal and external corners for a tighter neater look. The Cosmofin Membrane welds directly to the corners.
WOLFINATOR – Wolfinator is a structural grade adhesive that has been specially formulated for the bonding of Cosmofinsteel to absorbent & non-absorbent substrates including metals, ceramics, timber, glass, etc. It will also adhere to slightly damp substrates.
THF – Tetrahydrafuran cold welding solvent, for cold welding overlaps & connection of the membrane to PVC pipes.
UNIVERSAL PINS – The Universal Pins are the solution for fastening items directly to the Cosmofin Membrane without piercing the membrane itself. The product has an 80mm diameter base plate, which is made of Wolfin membrane (with a protruding 25mm vertical threaded bar and locking nuts) and is welded directly to the Cosmofin membrane for the securing of ballast retainers etc.
