Tanks: Cracks in engine casings are common defects. Due to defects, stress concentration, fatigue, and prominent external forces in the internal structure of the metal, cracks are often caused in different parts of the engine body. If this type of problem is solved by welding, the material will become brittle, deformed, and the strength will drop. At the same time, it will also lose electricity and equipment. The use of special adhesive technology to deal with this type of crack will achieve fast, good, and economical results.

Aircraft: Mainly subsonic or transonic flight, the fuselage, wing skin adopts aluminum alloy plates with a thickness of 1.5 mm or less, and some are only 0.4 to 0.8 mm thick, which are reinforced by corrugated profiles. The structure of riveting skin is so thin that it is very difficult, and the use of adhesive structure can not only overcome the deformation caused by riveting thin skin, but also the overall strength loss caused by riveting groove, reduce the workmanship, and shorten the assembly cycle. Moreover, the corrosion resistance, fatigue resistance and breakage safety of the structure are increased. In modern high-performance military aircraft, adhesives are needed for the sealing of the integral fuel tank of the wing or the integral fuel tank of the fuselage. The adhesive seal between the organic glass and the polyester belt in the cockpit of the enemy aircraft requires a high-performance adhesive.

Disguised material: For the Army's ground weapons, it is mainly a threat of 8 to 14 μm infrared thermal imager. The main way to achieve infrared stealth is to develop infrared camouflage coatings with different emissivity, through the different emissivity of the coating. Effective infrared image segmentation is carried out to achieve the goal of target and background Fusion. From the research content of infrared stealth coating, high-transparency adhesive is one of the technical approaches adopted. The use of resin in the infrared atmosphere of 8 to 14 μm does not contain absorption groups to achieve the low radiation specificity of the adhesive itself in the infrared window. Radar coating is a kind of functional material that can absorb electromagnetic waves, reduce the target radar characteristic signal, and make it difficult to be discovered and recognized. It is one of the main ways to achieve radar stealth of weapons and equipment. It is composed of absorbent and adhesive, which determines the physical mechanical properties and construction properties of the absorbent coating.
