Should I use a solvent adhesive or acrylic? What’s the difference between a removable and a repositionable adhesive? When does a removable adhesive become permanent? If you’ve ever asked yourself one of these questions, you’ll enjoy our second edition of the Sign College Newsletter. This week, we’ll talk about the adhesive compounds used in today’s graphic marking films and examine their strengths, weaknesses, and unique applications. Hopefully you’ll be better able to make choices that result in what I like to call “trouble free stickage”.
