Over the past couple months we’ve learned what masking tape is and how it’s made. We also talked about some additives that can be introduced to enhance the tape’s physical properties. In Part three of this series, we will briefly recap what we have already covered and discuss some new technologies that are trending in the industry as we move to the next generation of masking tapes that will help you achieve great results on the jobsite.
In Part one we talked about the composition of masking tape from a fundamental understanding. “Masking Tape” (a term most often used categorizing paper tapes) comes from the act of protecting or masking an area prior to the application of painting, coating or surface treatment. The composition of masking tape is made up of three layers: Backing, adhesive and release coat. The backing is generally made from a saturated crepe paper. The two types of adhesives used are Acrylic and Rubber (or Synthetic Rubber). The release coat controls the tape’s unwind values, its adhesion to backing values and adhesive consistencies. In other words – the release coat allows the tape to come off the roll easily and not stick to itself.
In Part two we learned about chemical additives that enhance the tape’s physical characteristics, allowing the tape to be used for specific applications. We discussed clean line technology, UV inhibitors and operating temperatures. Clean line technology is an additive applied to the edge of the roll, forming a barrier or blocking agent so paint cannot seep under the tape. UV inhibitors are additives necessary for a tape to properly perform outside or directly on windows exposed to sunlight. Generally speaking, your painter’s masking tape will work at its optimum around +70°F but will do the job properly between +50°F - +100°F.

| Paint and all related accessories go hand-in-hand |
New technologies will continue to be a priority for tape companies. In recent years you have probably noticed more specialized products designed for very specific applications. Some of these new masking tapes are made for delicate surfaces, textured walls and outdoor use among other things. Some tape has been developed with different kinds of adhesive and non-traditional backings.
The paint industry is constantly evolving and more and more new products will be introduced in the coming years. Paint and all related accessories go hand-in-hand and need to work in conjunction with each other. As Low VOC paints are gaining popularity and more legislation in certain states are requiring their use, painter’s tape needs to be compatible.
The tape aisle at your local big box or hardware store will continue to add new and different masking tapes to their shelves. But don’t stress - in the past few months you’ve learned about masking tape and should be more comfortable walking through the daunting tape aisle and making your purchase decision.
