Caution 

Keep ventilation,no smoking! 

Screw up the lid to avoid high thickness because of solvent's volatilization. 

Use the company's special diluter to reuse thickness if glue kristallization become white jelly-like under low temperature(under 5 centigrade),it belongs to natural physical phenomenon,it won't influence the use. 

To heat up and melt the glue in water 20-30 centigrade and stir evenly. 

Avoid joint layer meeting directly cold and wet wind when operate. 

Keep away from skin and eyes,if on,wash with cleaning water,and see doctor.

2.Daub glue evenly. 

3.Heat up the glued surfaces to 60-70 centigrade and keep 5-8 minutes. 

4.Bond the two surfaces.It is better to finish the bonding one time.otherwise it will affect the strength of adhesive. 

5.Press the bonded surface 10minutes,knock and roll the surface from one side to the other side to avoid air and add joint layer firmly.
