Surface treatment
All interfaces contacts with the glue must be cleaned and stored to ensure that there is no phosphorus (P), sulfur (S), nitrogen (N), organic tin (Sn), water, polyurethane and other catalyst toxic substances, so as not to cause curing obstacles and deterioration
Mix procedure
Formula of component A is cross linker and B contains platinum catalyst. The platinum catalyst can make the
component to do crosslinking reaction. So please avoid mixing A and B while you are using the operating tools
Curing
The curing of the glue is closed relate to the curing time, temperature as well as glue thickness. Mix ratio of A and B is 1:1. The proportion deviation has a certain effect on the hardness of glue, you can add addition of group A to improve the hardness
