The curing rate may be modulated by changing the weight ratio of composition A to composition B over the range of 12:1 to 8:1 according to different environment conditions.

2. The mixture of sealant can be classified into two methods, one by hand-made and the other by special extrusion machine. It is noticed that Showland SL-998 sealant should be scratched and mixed by the spatula along the same direction repeatedly to prevent gas bubble trapped in sealant in the method of hand-made. The homogeneity of mixture can be measured by butterfly-type method as listed in the following figure:

3. The surfaces of insulating glasses must be dry and clean.

4. Showland SL-998 should fill the joints completely which need to be caulked during the course of making insulating glass.

5. Gun mouth should be assured to move along the same direction at uniform velocity to make the joints full of sealant and prevent the gas bubble production due to moving too fast or back and forth in the method of using special extrusion machine.

6. The sealant overflowing the joints should be pressed back at once by spatula to make the sealant contacting with the sides of the joints completely and smooth the surface of the joints along the same direction
