FASpro™ Glue Dots are pressure-sensitive patterns of adhesive. They bond instantly, and are very safe and clean to use, leaving no sticky residue like double-sided tapes. FASpro™ Glue Dots are available in four different bond strengths or tack levels: Low, Medium, High and Super High. In most cases, super high tack creates a permanent bond, while low or medium tacks are considered removable. Low tack contains some oil. Test absorbent surfaces for bleeding. Additional sizes and roll lengths available for order.
