Seam Fabric

• Lightweight
• durable
• High Tensile and tear strength
• Non-raveling
• moisture, rot and mildew resistant

Invisilink® is a lightweight, yet super durable, tear resistant seam fabric. Invisilink® features stitch bonded polyester which is one of the strongest materials available to the roofing industry for use as reinforcement in cold process roofing.

Invisilink®’s characteristics provide an unusual combination of high strength properties with good elongation for excellent thermal stress force accommodations. The soft polyesters will readily conform to various roof surfaces such as embedded gravel and standing seam metal roof decks. It is also much easier to handle and apply properly than other soft polyester sheets.

Invisilink® is used with WetSuit® 1-Part or WetSuit® Trowel on new construction with seams, and gaps more than 1/4” wide. It can be applied by brush, roller or Neptune Coatings Seam Machine for large square footage applications.

Splits and cracks can be patched using WetSuit Trowel with Invisilink® polyester mat utilizing the 3-course method of repair:

1. Apply an 1/8” thick layer of WetSuit Trowel over the specified area, extending past it a minimum of 3” on all sides.
2. Embed Invisilink into the WetSuit Trowel and brush it to ensure full saturation with no wrinkles or voids.
3. Over the Invisilink, apply a final thin layer of WetSuit Trowel to cover the mat. Ensure all of the Invisilink™ is fully covered.

*Note: Invisilink is not required for all WetSuit applications. Please consult with Neptune Coatings.
