808AB-DH, Thermal conductive epoxy sealant, thermal conductive electronic sealant, thermal conductiv

808AB-DH is a dual dose epoxy resin thermal insulation sealing material widely used in insulation infusion, bonding, moisture-proof sealing, etc. for electronic components, electronic transformers, charging stations, filters, negative ion generators, capacitors, power modules, LED modules, circuit components, aquarium water pumps, power and electrical components, automotive components, electromechanical hardware, optoelectronic lighting, etc; After mixing, the viscosity is low, the flowability is strong, and there is an appropriate operable time; The cured material has high thermal conductivity, low shrinkage, bright and hard surface, strong adhesion and sealing, excellent chemical resistance, and excellent electrical and physical properties.

2、 Pre curing parameters:

Main agent 808A-DH curing agent 808B-DH

Appearance: Black, gray, white and other colors of liquid, transparent and slightly yellow liquid

Specific gravity 2.5 ± 0.05 1.05 ± 0.05

Viscosity (25) 15000-30000CPS 10-30CPS

3、 Mixing ratio: A: B=100:10 (weight ratio)

4、 Available time:

The usable time after mixing the main agent and curing agent depends on the total amount of mixing and the operating temperature. Usually, 100 grams of mixed glue can be used for 90-120 minutes at 25 ℃; Therefore, glue should be properly mixed according to actual usage to avoid waste.

5、 Curing conditions:

1. At room temperature, it usually only takes 24 hours for complete curing, 6-12 hours for initial curing, or 1-2 hours for curing at 80 degrees Celsius

2. In addition, our engineering department can adjust the curing time according to customer needs.

6、 Characteristics of solidified material

Voltage resistance Kv/mm 12 Temperature resistance ℃ 80-100

Hardness Shore D 75-85 Insulation Resistance Ω - cm 2.5 × 1013

Thermal conductivity w/mk 0.8-1.0 Water absorption%/24h less than 1
