The global adhesion promoters market was valued at USD 2.9 Billion in 2020 and is projected to reach USD 4.43 Billion by 2027, growing at a CAGR of 5.8% from 2021 to 2027. Use of adhesion promoters in composites, application of adhesion promoters in printed circuit boards, innovation of silane-based green tires, development of multilayer packaging, increasing applications in the electrical and electronics industry, and growing automotive sector in the emerging regions are some major factors boosting the market growth. However, factors such as negative environmental impact of some adhesion promoters and strict legislations against chemical-based adhesion promoters. Global market is surging owing to frequent acquisitions and launchings by the market players. For Instance, Momentive Performance Materials Inc. launched SilGrip. PSA810 pressure sensitive adhesives. SilGrip PSA810 adhesive can deliver dramatically advanced high temperature adhesion and allow customers to manufacture improved tapes that will perform at the ever-increasing processing temperatures required for applications such as flame spray and PCB masking. Adhesion promoters, also known as coupling agents, are compounds that work at the interface between an organic polymer and an inorganic surface to improve adhesion. It can be used as a primer between the substrate and the coatings, as a primer between layers of coatings, or as an ingredient in the formulation of paints and coatings, polymers, inks, and rubbers, among other things. Adhesion boosters are useful for items with low surface energy and in extreme high and low temperature settings. Silanes, maleic anhydride, chlorinated polyolefins, and titanate & zirconate are some of the most prevalent adhesion boosters on the market.
