Direction for using:

Prepare: Before starting to use the A, B component must be complete stirred by manual or machine, to avoid the property changed as filler sedimentation.

Mixing: Supplied Part A/Part B in a 1:1 ratio by weight, stirring homogenized in the clean container.

Degas: Normal degas: keep (20-30)min after potting in the module.

       Vacuum degas: before potting, extract (5-10)min during vacuum -0.08 MPa-0.1MPa

Dispensing: Dispensing the silicone on the clean surface, completed in the condition of good flowing.

Curing: Room temperature or with heating, curing speed increase along with temperature raising. Curing with heating in winter is recommended.

Storage:

12 months during 8-28 and keep away from sunshine and damp.

Packing:

5299Z A6, 10KG/drum

5299Z B6, 10KG/drum

Notice:

1, Silicone sealed storage, completed used after mixing, avoid wasting.

2, Keep away from children, and don’t touch with mouth and eyes.

3, It can not be cured if contact with the substances as below:

·N, S, P organic compound
