Operating Instructions

Preparation: A and B components stir well each before mixing together.

Mixing: Accurately weigh the A and B components, then according to the ratio and mix them in a clean container.

De-bubbling: Natural deaeration: Put the mixed sealant into the component and let it stand for 20-30 minutes.

Vacuum Deaeration: Put the evenly mixed sealant into the equipment of vacuum degree -0.08Mpa to 0.10Mpa and evacuate for 5-10 minutes.

Potting:Keep component surfaces clean and dry, potting the sealant in operating time.              

Curing: It can be cured at room temperature or by heating. It is recommended to use heating, cured at 80 ℃ for about 25 minutes, room temperature curing will vary depending on temperature.

Storage conditions

Store in a cool and dry place below 35 ℃.

Shelf life: 12 months.

Packaging specifications
