1050A / B epoxy casting material
I. Introduction:
1050A / B, the Department of high-performance imported epoxy resin and a polyamine curing agent combination of materials, a mixture of low viscosity can be used for a long time, after curing high hardness and excellent electrical characteristics, any color according to customer requirements.
Second, the general performance:
Test methods or conditions of the test items 1050A 1050B
The Appearance head measured colorless liquid colorless liquid
Density of 25 ℃ g/cm3 1.1 ~ 1.2 1.01 ~~ 1.05
Viscosity 40 ℃ mpa to s 800-1300 30-70
Shelf life at room temperature ventilation from year to year

Third, use:
Item Unit or condition of 1050A / B
Mixing ratio of the weight ratio 100:50
Time 25 ° C, hrs 1
Curing conditions ℃ / hrs 25 degrees / 24 hours
Note: If you need a mold release, the first to surface evenly brushing a layer of silicone oil in the steel mold and then placed in a 150-degree oven, pre-bake 1 hour, cooling, silicone oil in the steel mold the inner surface of the formation of the isolation layer, after preparation, stir good AB mixed glue into the mold, and then 80/4 hours to +140 degrees / 3 hours to cure, after the completion of cooling demoulding can be!
 
Tools: electronic scales, measuring cups (such as: plastic cups, paper cups), glass (or mixing gun); 1050A cold 60-70 degree warm-up in two hours, its viscosity thinning, easy to operate.
2 weighing: open electronic scales, measuring cup placed above to remove tare, add 100 grams A plastic, and then add 50 g of B adhesive. (Note: (1) must be a weight ratio, some customers there is no electronic scales, he graduated cylinder to measure it is not desirable, because the proportion of AB glue, it is difficult to achieve a suitable proportion, so the lead with a good glue harden. do not more or less plus B glue to control the hardening speed of the glue, otherwise it may lead to hardening can not.)
Mixing: will weigh a good AB mixed glue, using the glass rod to fully stir about 3 minutes (up and down left and right rotation), (Note: If the mixing is uneven, and may lead to local non-hardening phenomenon.)
Package: mixing good mixing glue individually poured into pre-prepared products (preferably within half an hour, exhausted, to prevent the glue in a chemical reaction to produce large amounts of heat, resulting in a rapid increase in viscosity glue. harden rapidly).
Curing: 25 degrees / 24 hours
Cleaning: You can use acetone or ethanol.
  
Advantages of this product: colorless, transparent and bright, smooth surface, high temperature resistance, excellent electrical insulation properties
Fourth, use:
    Casting molding for electrical module components.
 After the curing characteristics:
Project unit or conditions 1050A / B
Hardness Shore-D> 80
Of TG ° C to> 55
Volume resistivity of 25 ° C, Ω, • cm 1.5 × 1015
Surface resistivity of 25 ° C, Ω, 1.2 × 1014
25 ° C, dielectric strength kV / mm> 20
Dielectric constant 25 ° C, the 1MHZ 4.2 ± 0.1
Dielectric loss tangent of 25 ° C, 1MHZ <0.01
Compressive strength kgf/mm2> 30
Flexural strength kgf/mm2> 15
Impact strength kgf/mm2> 5.1
Shrinkage% <5
 Six, storage, transport and precautions:
A. Such products of non-dangerous goods, a general chemical storage, the storage period to see the drums.
Two. Sights used in the product model, then the condemnation;, accurately weighed, stir evenly; weighing more than 200 grams, the use of shortened.
3. Customers can add their own creams and fillers according to actual needs.
Seven, packaging specifications:
    Packaging A: 20KG ± 90g of iron or 200KG / drum; B was: 5KGG ± 90g plastic barrels or other containers.
 
* Note: The above performance data for the product in 70% humidity, the typical data of the test temperature of 25 ° C for customers to use for reference and can not guarantee all the data that can be achieved in a particular environment. Please customers, subject to the measured data
