Limit
It is important when selecting components for a project that adhesion and compatibility tests are carried out, and found to be successful before the project starts. MF881 adhesion with glass and Alu. spacer must be tested in advance and compatibility of gaskets, backer rods, setting blocks and other accessory materials with MF881 better to be tested in advance.
Regarding facade structural glazing, primer is not usually required when using MF881. However, it is essential that adhesion be tested prior to use.
