Directionsfor use :
1. Surface cleaning: clean the surface to be embedded, remove rust, dust, oil and so on,keep clean and dry.
2. Adhesive preparation and embedment: mixing component which has filler(part A and/or part B)in the original packaging before weighing, then according to the ratio and the actual quantity needed, weigh out the corresponding A, B component, stir well in a clean container.To ensure a void-free embedment,vacuum deairing is recommended. A residual pressure of 1-5mm mercury applied of 5-10 minutes will be sufficiently. When potting,carefully pour the mixture along a certain position of component to be sealed. Vacuum potting
is recommended for high-voltage electrics and complex geometries .
3.Curing: the potted components shall be cured at room temperature,it takes 8-10 hours in generally. Rapid cure can result by heating, it takes 25 minutes under the situation of 80~ 100℃.
4.The color of Component A or B maybe deepen, turn yellow, or slightly layering settlement after storage a period. And that doesn't affect to use. Please mix well before use.
Note:
Contact with following material will not cure: organo-tin compound and silicon rubber containing organo-tin compound; sulphur, sulfide and rubber containing sulphur; amine
compounds and materials containing amine; surface treated with solder flux. When need to bond or pot these special materials, Please test whether can be cured and bonded
in advance,and then application.
