Tesa® butt-splicing tape for jointing of metal webs (4990) is an industrial splicing tape designed for use with a tacky acrylic adhesive and a black PET fabric backing. This single-sided tape is specifically engineered for connecting metal webs that can withstand high temperatures and endure high web tension. The adhesive features a balanced combination of rapid bonding and exceptional resistance to elevated temperatures. Tesa® 4990 also exhibits superior tensile strength for high-tension applications. The tape incorporates in-line adhesive curing technology to counteract the softening effect of adhesives at high temperatures. This results in consistently strong adhesive performance across a wide temperature range.
