In this paper,the compatibility between PPG's low-density general purpose sealant PR1776M B-2 for aviation and Flamemaster's polysulfide sealant CS2415 B-2 was studied.The compatibility test was developed according to AS5127/1,and the stripping strength,failure interface and failure form of the two sealants were tested.The results show that PR1776M B-2 sealant and CS2415B-2 sealant adhere to each other,and the peel strength reaches 8.108 kN/m,which is much higher than the peel strength of single sealant.The failure does not occur at the interface between the sealant and the test piece,the sealant and the reinforcement layer,and the failure form is 100%cohesive failure,and the two show excellent compatibility.This paper provides a reference for improving the selectivity of sealants and the maintenance economy in the maintenance of the maintenance division.
