Thermally Conductive Epoxy Potting Compound

JOME 3113-1 A/B

 High-temperature two-component epoxy potting

Apply for electronic componets

PRODUCT DESCRIPTION

JOME 3113-1A/B is a two-component solventless, room temperature curing epoxy potting material for  automotive,  automotive  electronics,  power tools,  reactors,  instruments  with  high  thermal  conductivity

requirements of the product package protection, and has excellent adhesion and heat resistance.

FEATURES

l Heat curing will bring high heat resistance

l Excellent adhesion, anti-cracking

l Low CTE linear expansion coefficient

l Having a high thermal conductivity

l Excellent electrical insulation, stability

l Long-term use at -50  ℃ – 200 ℃

l Very low water absorption, good waterproof, moisture resistance

TYPICAL PROPERTIES

Apply for electronic componets

Note:

1. Theabovedata curing conditions tested were 100  ℃  * 2h
2. The measured data table is under a specific condition, for reference, the resulting data does not guarantee that theclient can fully consistent with theactual use.

Operation process

l Preparation: Put A material original packaging barrels at 40℃ environment preservation 2 hours, after take out, compound viscosity is thinning, lower.

l Or use directly at normal room temperature.

l Mixing ：With the A component of the filler will contain the time to precipitate down, so use a stirrer to make the filler and resin liquid mixed evenly.   ThenweighingA /  B components with  Ratio  100:8, mixingthoroughly for several minutes. After, the finished liquid will be ready for potting.

l Component B may occur during storage or agglomeration of crystal (a normal case), if required before use crystalline placed in an oven at 60 ℃to melt it, and then cooled to room temperature and after use, which does not affect its performance.

l The exposed component B will be hydrolyzed in moisture and the color of hydrolysate will show the color of white as friable powder.

l Good potting device, if necessary, vacuum may continue to help increase the electrical properties of

the device.

Curing conditions

Recommendedcuring process would be chosen as below:

25℃* 24h at room temperature

80℃ * 3h

100℃ * 2h,   reach the heat resistance grade B;

100 ℃ * 2h + 120  ℃ * 1h , reach the heat resistance grade F;

If working temperature is below 150 ℃ ,   the final curing temperature can be ignored.

Packing and Stocking

l Avoid the sun and heat, stock under sealing.

l Shelf life at 25τ: Part A 12 months, part B 12 months;

l If expired should be tested first.

l Part A :20kg/plastic drum;    Part B: 0.8kg/bottle or 2.4kg/pot
