SEALING COMPOUND CONTAINING POLYTHIOETHER Russian patent published in 2012 - IPC C08G18/52 C08L75/08 C08G18/10 C09K3/10 

FIELD: chemistry.

SUBSTANCE: invention relates to a sealing compound containing polythioether, where the sealing compound (a) essentially does not contain volatile organic compounds; (b) can be applied via pulverisation and (c) is fuel-resistant, where the polythioether contains polythioether-polyurethane and/or -polythiourethane with functional isocyanate groups and polythioether with functional amino/hydroxy groups. Described also is a multi-component sealing compound containing (a) a first component which contains polythioether-polyurethane and/or -polythiourethane with isocyanate functional groups, and (b) a second component containing polythioether with terminal amino/hydroxy groups. The invention also describes an aerospace vehicle having a hole which is at least partly sealed by said sealing compounds, and the hole itself, which is at least partly sealed by said sealing compounds.

EFFECT: obtaining sealing compounds which essentially do not contain volatile organic compounds, which are fuel-resistant, can be applied via pulverisation and harden fast in ambient conditions, and have good elasticity at low temperature.
