 HOW TO USE

l  Mix part A base to Part B curing agent at a ratio of 6:1 by weight or 4:1 by volume, and then pot the mixture into the parts of substrates where needed, place at room temperature for initial curing for about 2～4 hours before conducting the next procedure. If precipitation occurs in Part A, just stir it well before use, and this does not affect the performance of the sealant.

l  When using automatic dispensing machine, set at a ratio of 6:1 by weight or 4:1 by volume of part A to Part B for a test first and then put into use.
