Skin protection, microencapsulated

Microencapsulated adhesive Reactive adhesive mixture, with the (liquid) components encapsulated by a protective skin in the form of finest drops, preventing a reaction during storage. Only after the destruction of the capsule wall, for example, by screwing a nut onto a suchlike coated screw, does a chemical reaction set in and an adhesive layer develop. 

Microencapsulated Cl fixed on the surfaces of metal parts forming immovable joints have found application in various industrial sectors. The interior of the shells is liberated when the parts are brought into contact and the capsules become squashed. This technique is used for antirust protection of rivet joints of the skin of airplanes. Microcapsules with Cl are carried, with minimum outlay, to the demanding corrosion sites of casing and drilling pipe strings at excavation sites of oil and gas deposits. The effective use of inhibited microcapsules has not been fully realized due to a number of reasons, including technical and economic ones.
