9000GA/1042B special epoxy material sensor
I. Introduction:
Imports of high-performance epoxy resin system 9000GA/1042B amine curing agent composition and diversity of material, a mixture of low viscosity, can be used for a long time, after curing, high hardness, heat resistance up to 130 degrees, excellent electrical characteristics can be arbitrarily adjusted according to customer requirements color.
Second, the conventional performance:

Third, use:
Item Unit or condition 9000GA / B
Mixing ratio of 100:18 by weight
You can use the time 25 ℃, hrs 1
Curing conditions ℃ / hrs 60 degrees / 25 degrees or 2-3 hours / 24 hours
 
1 tool: electronic scales, measuring cups (such as: plastic cups, paper cups), glass (or mixing gun); 9000GA cold 70 degrees warm when needed 2 hours, a viscosity-thinning, easy to operate.
2 Weighing: on electronic scales, placed above the measuring cup to remove tare, add 100 grams of adhesive A, B and then add 18 grams of plastic. (Note: 1 weight ratio must be some customers without electronic scales, the amount of his take on the use of graduated cylinder which is not desirable, because the proportion of different AB glue, it is difficult to achieve a suitable proportion of cases, so with good cause glue does not harden. 2 do not increase by more or less glue B to control the rate of hardening of the glue, otherwise it might not harden.)
3 mixing: mixing the weighed AB glue, stir with a glass rod (vertical and horizontal rotation) about 3 minutes, (Note: if uneven mixing, may lead to local non-hardening phenomenon.)
4 packages: the stirred mixture of glue, one by one into the pre-prepared products (preferably in a half hour run out to prevent the glue in chemical reactions produce large amounts of heat, leading to a rapid increase in viscosity of the glue, short rapid hardening).
5 Cure: 60 degrees / 80 degrees or 2-3 hours / 2 hours
 6 Clean: You can use acetone or ethanol.
  
The product advantages: colorless transparent bright, smooth surface, high temperature, good electrical insulation properties!
Fourth, use:
    For sensors, power modules and other components of cast molding.
 Fifth, the curing characteristics:

 Sixth, storage, transportation and precautions:
1. Such products of non-dangerous goods, as a general chemical storage and transportation, see the product shelf life drum.
2. Please use the sights on the product model, then the condemnation; accurate weighing, please fully stirred; weighing more than 200 grams, the use period will be shortened.
3. Customers can add their own creams according to actual needs and filling.
7, Packing specifications:
    Packing for the A: 20KG ± 90g iron or 200KG / drum; B: 5KGG ± 90g plastic barrels or other containers.
 
* Note: The above performance data for the product in 70% humidity, temperature 25 ℃, the typical test data for customers reference, and can not guarantee that in a specific environment can be achieved when all the data. Please use the customer, subject to the measured data
