Seam Tape is made of a 5 oz/yd2 spun bond polyester with high tensile, tear and puncture strength. It is available in two forms, 1) one side coated or 2) uncoated. The coated seam tape has a very thin layer of film that provides vapor barrier to one side. The vapor barrier or coating prevents adhesive from bleeding through seam tape, but allows fiber web to become fully saturated to get maximum mechanical bonding with backing of synthetic turf. It also prevents contamination or negative influence from chemicals that may be in or on surface in which synthetic turf is being installed. Adhesive is applied with glue in a cocking gun. When using one side coated seam tape, it is important to mount coated seam tape in glue box such that adhesive is applied to uncoated side of seam tape.
