Insignia Adhesive Backed Black 54” is a high tack, residue free, adhesive-backed polyester material. Insignia material requires no sewing when applied to sailcloth! Simple and easy to use, adhesive insignia works great for numbers, insignia, spreader patches, and as an economical repair tape. The paper backing features a grid for easy patterning. This polyester is inherently UV resistant, but does break down faster than acrylic, vinyl, or UV protected Dacron in the sun.
