A form of mechanical seal, sealant is a substance used to stop fluids from passing through gaps in materials. Sealant is sometimes used interchangeably with caulking in the construction of buildings and has similar functions in preventing the transfer of heat, sound, and dust.
Sealants might be temporary or permanent, weak or strong, flexible or rigid. Although sealants are not adhesives, some of them have adhesive properties and are referred to as structural sealants or adhesive sealants.
The Global Mix-on-Demand Sealants Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
3M Mix-on-Demand Aerospace Sealant AC-350 B-2.Fast-curing, intermediate-density polysulfide sealant from 3M Aerospace Sealant, model number AC-350 B-2, comes with a variety of advantages over competing sealants.
The 29 CFR 1910.1026 requirements of OSHA may be more easily met by using a non-chromated product. It maintains its shape, won’t sag or severely shrink, and requires little to no rework because there are no additional solvents.
The two-component AC-350 B-2 sealer provides remarkable resistance to aviation gasoline and jet fuel, as well as resistance to chemicals and petroleum products that are frequently used in the aerospace and aviation industries.
It is manganese dioxide cured. This two-component sealant mixes to form a thixotropic paste with exceptional tooling qualities. It is the perfect formulation for sealing fuselages and integral fuel tanks, as well as for repairing them.
Under harsh conditions of temperature, corrosion, and stress, 3M Aerospace Sealant AC-350 B-2 maintains its flexibility and bond strength on the majority of metal substrates, including aluminium, titanium, steel, stainless steel, dissimilar metals, and numerous coatings.
Additionally, it offers superb adhesion to a variety of composite materials and organic coatings utilised in the aerospace sector.
Unlike some of the competitors, it doesn’t add solvents to the formula, giving more usable sealant per unit of purchase. Because there is minimal to no shrinkage and sag brought on by solvent evaporation.
Due to the fact that AC-350 B-2 experiences little to no shrinkage and sag from solvent evaporation, it can help reduce production time by maintaining the final shape from the outset.
Reduce assembly and processing times since sealant can be spray painted when it reaches the end of its useful life.
