Hot melts aren’t glamourous adhesives by any means, and they’re not a  product we’ve often covered in our blog, but today we’ll explore several types of hot melt adhesives from our in-house brand, Chem-Set, and where and when you should use each of them. Whether you’re a flooring contractor or a package handler, we hope this quick guide to your next hot melt project serves you well.

Hot melts are unique in the adhesives world because they can actually be reused after initial activation. Comprised of thermoplastic polymers, hot melts can be repeatedly heated or cooled without any real changes to their chemical make-up. Hot melts are generally called upon when fast, clean, and no-mix bonding is the preference, like adhering wood, cardboard, paper, fabric, vinyl, leather, and more.
