AdTech has led the hot-melt adhesives industry for over 40 years, and we continuously seek to improve our products, and inspire our customers with innovative bonding solutions. In addition to a full line of crafting and industrial hot-melt glue guns, AdTech's team of chemists and engineers develop and produce a wide range of hot-melt adhesive formulas for bonding nearly any material. Crafters also love AdTech's line of glue runners, which makes paper crafting fun and mess-free. We're located on New Hampshire's beautiful, but short, coastline where all our products are developed, engineered and tested.
