Forecast Global Aerospace Sealants Market to be Worth 1.5 Billion USD in 2022

Aerospace sealants are substances curing within a certain period of time, to isolate environment such as isolation of fuel/solvent, insulation, and flexible to play a supporting role in aerospace manufacturing, aerospace maintenance repair, and overhaul (MRO) industry.
There are 3 classes of tank sealant as defined by viscosity. Class B sealant is the paste consistency sealant that is most commonly used in sealing homebuilt aircraft tanks. Class B sealant is designed to be applied using an extrusion gun such as a Semco or Techcon gun or by using a spatula or similar tool, and does not sag or run on vertical surfaces. Class A sealant is a lower viscosity, pourable sealant designed to be applied by brush. Class C sealant is an intermediate viscosity sealant designed for brushing or rolling on faying surfaces. Class C sealants are not common in homebuilt aircraft as their application and cure times are quite long compared to Class A and B sealants.
Aerospace Sealants are defined by their product compound; there are polysulfide sealants, polythioether sealants, silicone sealants, and other types. Aerospace sealants can be classified as Polysulfide Sealants, Polythioether Sealants, Silicone Sealants and others in terms of material type. Polysulfide Sealants is the major kind of aerospace sealants due to its superior quality and reasonable price. The production of Polythioether Sealants is quite concentrated, with USA, Germany and France as the major producing area. The market of Silicone Sealants is still in its emerging stage, with a global market share of 5.91% in 2015. It is estimated that the market of Silicone Sealants would be expanded with selling price decrease.
