What is Acrylic Adhesive?
Acrylic adhesive is a kind of acrylic polymer prepared by different kinds of acrylate monomers, like 2-Ethylhexyl acrylate and butyl acrylate, by using semicontinuous emulsion and solution polymerizations. When the acrylic polymer is synthesized to a certain molecular weight range, it will become sticky and adhesion with pressure given, as we call Pressure- sensitive adhesive. When the molecular weight of the acrylic polymer goes much higher, then it will become optical clarity and stiffness acrylic sheet.
Acrylic adhesive as a Pressure-sensitive adhesive (PSA, self-stick adhesive, self-adhesive) forms a bond when pressure is applied to bond the adhesive with a surface. Thus PSA can be widely applied in many industries, such as many kinds of tapes for packaging industries, labels, stickers, tags for merchandise, 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 adherend. The bond has strength because the adhesive is hard enough to resist flow when stress is applied to the bond. Once the adhesive and the substrate adhere, there are also molecular interactions such as van der Waals forces involved in the bond, which mainly contribute to the final bond strength.
Acrylic Adhesive V.S. Rubber Adhesive
Acrylic adhesive is also a practicable and alternative solution to some applications of rubber-based adhesive. Compared to the same application, one drawback of the rubber adhesive is that the price is relatively higher than acrylic glue. Another drawback is that rubber will deteriorate quickly in outdoor applications. With the development of material technology, the acrylic adhesive is an adhesive with the ability of weather resistance, and better performance but at a low cost. Below is the table of comparison.
Wide applications of acrylic adhesive
Chemix Guru provides many different applications of pressure-sensitive adhesive; simply classified into the solvent-based and water-based adhesive. Each one has its own properties and adequate applications.
