I. Introduction: At room temperature hardening plastic electronic confidentiality \ modules confidentiality plastic \ 904-1A/-1B plastic chips confidentiality is a two-group-type potting material at room temperature hardening, which become dense in the cured solid structure, high hardness, heat good performance, it is extremely difficult to demolish, to protect, waterproof, the role of secrecy.

Second, conventional performance:

Test items	Testing methods or conditions	904-1A	904-1B
Appearance	Visual	Black viscous liquid	Colorless transparent liquid
Density	25℃ g/cm3	1.5~1.6	1.00~1.10
Viscosity	25℃ mpa·s	3000~5000	150~300
Retention period	Room ventilation	Six months	Six months

Third, the use of technology:

Item	Unit or the conditions of	904-1A/904-1B
Mixing ratio	Weight ratio	100:20
Can use the time	25℃，35g，hrs	0.5
Curing conditions	℃/hrs	25/24 or 60 / 3

Fourth, use: apply to sensors, hybrid circuit modules, small electronic components such as confidentiality.
Fifth, after the curing characteristics:

Hardness	Shore-D	80
Volume resistivity	25℃，Ω·cm	1.0×1014
Dielectric Strength	25℃，kV/mm	15
Impact strength	Kg/cm2	7
Permittivity	25℃，1MHZ	4.0±0.05
Dielectric Loss Tangent	25℃，1MHZ	0.02

6, storage, transportation and Cautions:
1. Such products of non-dangerous goods, as a general storage and transportation of chemicals, product packaging, see barrels of storage period.
2. Please see the product model, and then pigeon-holing; accurate weighing, please give full uniform mixing.
3. By encapsulating the device was 100 ℃ / 1 ~ 1.5hrs drying to remove water, cooling to 30 ~ 40 ℃.
4. Encapsulation when the attention should not be dipping fast speed in order to ensure uniform impregnation.
7, packing specifications: Packaging for metal containers 5KG or 25KG.
　

Note: The above performance data for the product in 70% humidity, the temperature at 25 ℃ typical testing data for customers reference and can not guarantee that in a particular environment can be achieved when all the data. When your customers use to the measured data.
