It’s All About Acrylic Adhesive
Acrylic adhesive is a kind of acrylic polymer prepared from different types of acrylate monomers, such as 2-Ethylhexyl acrylate and butyl acrylate, using semi-continuous emulsion and solution polymerizations. When the acrylic polymer is synthesized in a certain molecular weight range, it will become sticky and stick with pressure, as we call pressure-sensitive adhesive. When the molecular weight of the acrylic polymer is much higher, it will become an acrylic sheet of optical clarity and stiffness.
Pressure-Sensitive Adhesive
An acrylic adhesive such as pressure sensitive adhesive (PSA, self-adhesive, self-adhesive) forms a bond when pressure is applied to bond the adhesive to a surface. Therefore, PSA can be widely applied in many industries, such as many kinds of packaging industry tapes, labels, stickers, commodity labels, etc.
Pressure-sensitive adhesives (PSA) are designed with a balance between adhesion and cohesion. The bond forms because the adhesive is soft enough to wet the adherent. The joint has strength because the adhesive is hard enough to resist flow when a stress is applied to the joint. Once the adhesive and the substrate bond, there are also molecular interactions, such as van der Waals forces, involved in the bonding, which mainly contribute to the final bond strength.
Acrylic Adhesive V.S. Rubber Adhesive
Acrylic adhesive is also a good alternative solution for some rubber-based adhesive applications. Compared with the same application, a disadvantage of rubber adhesive is that the price is relatively higher than that of acrylic glue. Another drawback is that the rubber will deteriorate quickly in outdoor applications. With the development of material technology, the acrylic adhesive is an adhesive with weather resistance ability and better performance but low cost.
Wide Applications Of Acrylic Adhesive
Pressure-Sensitive Adhesive For Car Wrapping
CG-18028 is the acrylic adhesive for car wrap and satisfies the application of car wrap films. The adhesion is strong enough for metal, wood, or other plastic materials. Besides, it can also be applied to produce film for outdoor advertising banners, etc. Therefore, PVC-based products and brand labels are also applicable.
Acrylic Adhesive For Painter Protection Film
CG-18101A is a one-part pressure-sensitive acrylic resin and features a heat-activated cure. With medium initial tack, adhesion, and moderate tear strength, it is also good in high-temperature resistance and low-temperature tolerance. Applicable to paint protection film.
