Before potting,package Aand B of the WCC-5217 model must respectively vacuum deaearated,then should be mixed by high speed stirring.WCC-5217(M) is suitable for deaearated potting process or hand-made potting process after package A and B are mixed.
Component A:vacuum deaearate with stirring for 4-6 h at 60±5 and 1-3 mmHg of absolute pressure;
Component B:vacuum deaearate with stirring for 3-4 h at 35-40 and 1-3 mmHg of absolute pressure.
Adjust the ratio of component A and component B after vacuum deaearation to 100:30(WCC-5217) and to 100:28 (WCC-5217(M))(by weight)respectively.
Preheat the devices to be potted at 90-100 for 2-6 h.
Put the devices preheated into a vacuum casting-potting machine and wherein perform the potting operation at 5-8 mmHg pressure.
Put the potted devices into a curing oven and where in cure them under given curing condition.

Before potting,package Aand B of the WCC-5217 model must respectively vacuum deaearated,then should be mixed by high speed stirring.WCC-5217(M) is suitable for deaearated potting process or hand-made potting process after package A and B are mixed.
A.Component A:vacuum deaearate with stirring for 4-6 h at 60°C±5°C and 1-3 mmHg of absolute pressure;
Component B:vacuum deaearate with stirring for 3-4 h at 35-40°C and 1-3 mmHg of absolute pressure.
B.Adjust the ratio of component A and component B after vacuum deaearation to 100:30(WCC-5217) and to 100:28 (WCC-5217(M))(by weight)respectively.
C.Preheat the devices to be potted at 90-100°C for 2-6 h.
D.Put the devices preheated into a vacuum casting-potting machine and wherein perform the potting operation at 5-8 mmHg pressure.
E.Put the potted devices into a curing oven and where in cure them under given curing condition.
5.Application note:
A.The fillers in component A stocked for long time tend to precipitate,therefore it must pay attention to homogeneously agitate before use.
B.The curing agent tend to crystallize at low temperature in winter,it must heat them to 70-80°C in the use (fully solubilized),having no influence on quality.
C.The curing agents very easy to absorpt humidity tend to form precipitate which can reduce the shelf-life and have influence upon quality.It must be used up as soon as possible,if once it is unsealed,and pay attention to closely cover the rest.
Storage:25°C in a dry place for 1 year.
Transport:
As ordinary chemicals,because no fire-and explosion-hazardous.
