Direction for use

1. 1 glue injection: 90 ~ 100 ℃ preheated A component 2～3 hour(make sure adhesive hot enough, viscosity is low),Stir evenly inhaled or into the vacuum tank with agitator (Semi automatic filling and sealing potting process must first accurate weighing A component and then poured into tank). 80 ~ 90 ℃ while stirring vacuum for 2 to 3 hours(to no bubbles),keep warm and waiting to use.

A. semi automatic filling and sealing process: accurate weighing in component B, A:B =100:28,poured into which vacuum tank loaded accurately weighing A components,60 ~ 65 ℃ while stirring vacuum for 30 minutes,until no bubbles. Potting process begin, after potting Put in the oven to curing.

B. Automatic filling and sealing process:poured B component into which vacuum tank loaded accurately weighing A components, 35 ~ 45 ℃ while stirring vacuum for 30 minutes. Then adjust the A component and the B component of the discharge ratio(Weight ratio A:B =100:28；Volume ratio A:B =100:44),after ratio adjust, start inject adhesive,keep the temperature 60～65℃.After adhesive injection, put in the oven to curing.

2.Curing:put in 90℃ oven 3 hours, and slowly warming up to 130℃(warming up time keep in 30～40 minutes),curing in 130℃ 2.5～3 hours,after curing slowly cooling to 50℃, and take it out of oven(cooling time keep in 60 minutes).

Attention

Every time mix adhesive need keep in 5-10KGS,mixed adhesive should finish used in 1 hour. The Vacuum degree of vacuum tank and vacuum room should as low as possible.
