Is it “nail resin”, “glue”, or is it maybe “adhesive”? This question illustrates a big problem in the beauty industry in general and demonstrates how confusing nail industry terminology can be. Why does this continue to happen? Largely because nail product marketers too often use incorrect terms to describe their products or services, which further reinforces the use of these terms. The trade magazines sometimes do this as well. Don\u2019t get me wrong, I\u2019m not blaming nail marketers and the magazines, they are just responding to the words nail professionals use every day. That\u2019s their job!<\/p>\n\n\n\n
It seems to me that much of the incorrect terminology comes from nail schools, educators, and veteran nail technicians who don\u2019t keep up with the latest educational information. That\u2019s why I focus on providing this type of information to educators. They are our best hope for improving this situation and the industry. In practical terms, resin and glue are the same, and it is a misunderstanding to think they are different. <\/p>\n\n\n\n
How did this misunderstanding occur? To understand, we have to travel back to ancient times. The word glue actually refers to animal-based adhesives. Glues were originally made from proteins extracted from animal hides, horns, and hooves. In the \u201930s, that new-fangled Elmer\u2019s Glue was developed. It was a breakthrough. This adhesive used a protein found in milk called casein. Protein-based glues have been used since ancient times to adhere things together and for thousands of years, all was well. The confusion began in the late \u201940s when Elmer glue changed formulas from milk protein to a synthetic polymer called polyvinyl acetate or PVA. <\/p>\n\n\n\n
This polymer belongs to a unique class of polymers that are called \u201cresins\u201d. Originally the term \u201cresin\u201d was used to describe the thick, sticky sap that oozes from certain trees, bushes, and plants. The natural resins were also used by the ancients both as glues and as protective, water-proof coatings for wood, leather, and cloth. They were even used by early artists to adhere pigments to walls to make cave paintings. Interestingly, when Elmer\u2019s changed their formula, the term \u201cresin\u201d came to be used to describe synthetic substances that could mimic the thick and sticky properties of natural resins.<\/p>\n\n\n\n
How does this apply to nails? Nail adhesives, wraps, resins, and no-light gels are all based on a synthetic monomer called cyanoacrylate which is not very thick or sticky. Since this monomer will eventually harden to form a sticky polymer, they are called resins; even though this is not technically correct, since they aren\u2019t resins, they are monomers. What\u2019s the bottom line?\u00a0\u00a0These products are no more glues than they are resins. <\/p>\n\n\n\n
