100BA/H-426 high temperature epoxy resin casting material
I. Introduction:
Import of High Performance 100BA/H-426 and durability of epoxy curing agents alicyclic material, a mixture of low viscosity, can be used for a long time after curing, high hardness, heat resistance up to 150 degrees, excellent electrical characteristics can be any color according to customer requirements.

Note: If you need to stripping, first to the steel mold silicone oil even brushing the inner surface layer, and then placed in 150 degree oven, bake 1 hour pre-cooling, the silicone oil in the steel mold will form the inner surface of isolation layer, and then after the preparation, mixing glue AB Stir well, pour into the mold, and then 80 degrees / +140 degrees 4 hours / 3 hours curing, cooling after ejection can be!
1. Tools: electronic scales, measuring cup (such as: plastic cups, paper cups), glass (or mixing gun); 100BA warm-cold 70 degrees is required 2 hours, so thinning viscosity, easy operation.
2. Weighing: Open electronic scale, remove the skin above the measuring cup placed on weight, add 100 grams of 100BA glue, then add 24 grams of H-426 glue. (Note: 1. Must be to weight ratio, some customers do not electronic scale, the amount of his take on the use of cylinder which is not desirable, because not the same as the proportion of AB glue, it is difficult to do the right proportion of cases, so with a good cause glue does not harden. 2. Do not pay more or less by adding B to control the glue hardening glue speed, otherwise it might not harden.)
3. Mixing: AB will be weighing a good mixture of glue, use a glass rod to mix (vertical and horizontal rotation) about 3 minutes (Note: If mixing uneven and may lead to local non-hardening phenomenon.)
4. Package: one by the stirred mixture of glue into the pre-prepared products (preferably within half an hour run out to prevent the glue in chemical reactions produce large amounts of heat, leading to rapid rise in viscosity glue, short rapid hardening).
5. Curing: 80 ° / 4 hour +140 degree / 3 hours
6. Cleaning: You can use acetone or anhydrous alcohol.
The product advantages: black shiny, smooth surface, high temperature, excellent electrical insulation properties!

VI, storage, transportation and precautions:
1. Such products of non-dangerous goods, as a general chemical storage and transportation, storage period, see drum.
2. Please use the sights of the product model, then the condemnation; accurate weighing, please, stir; weighing more than 200 grams, the use period will be shortened.
3. Customers can add their own color paste according to actual needs and fill.
VII, packaging specifications:
Packaging 100BA: 20KG ± 90g of iron or 200KG / iron drum; H-426: 5KGG ± 90g plastic bucket or other container.
* Note: The above performance data for the product in 70% humidity, temperature 25 ℃, the typical test data for reference purposes only customers, and can not guarantee that a particular environment can be achieved when all the data. Please use customers, subject to the measured data.
