We are actively engaged in supplying ATH Flame Retardant Epoxy (834ATH). Our entity is based in Maharashtra, India. The 834ATH Flame Retardant Epoxy Encapsulating and Potting Compound is a two-part, economical, electronic-grade, self-extinguishing, flame retardant epoxy that provides an excellent physical, chemical, and electrical protection. It offers a degree of thermal conductivity. It protects against the static discharges, shocks, vibrations, and mechanical impacts. It is extremely resistant to the environmental humidity, salt water, and harsh chemicals. It also helps to hide and restrict access to intellectual property and it is much harder to remove than the standard epoxy encapsulating compounds.
- Certified UL 94V-0 (File # E334302)
- Specification Verified as per UL 746A
- Cost effective
- Increased thermal conductivity
- Mix ratio 2A:1B compatible with most dispensing equipment
- Resistance to water and humidity allowing submersion if needed
- Protects electronics from moisture, corrosion, fungus, thermal shock, and static discharges
- Free of solvents
Details : The 834ATH epoxy is used to pot or encapsulate the printed circuit assemblies in a protective block. The cured epoxy improves reliability, operational range, and lengthens the life of electrical and electronic parts.
Application Instructions :
- Follow the procedure below for best results. If you have little or no experience with the 834ATH epoxy, please follow the long instructions instead.
- The short instructions provided here are not suitable for first time users.
To Prepare 2:1 (A:B) Epoxy Mixture :
- Stir and fold the material in the Part A container until fully homogenous.
- With a different stirrer, stir and fold the material in the Part B container until fully homogenous.
- Measure two parts by volume (or weight) of pre-stirred A, and pour in the mixing container.
- Measure one part by volume (or weight) of pre-stirred B, and slowly pour in the mixing container while stirring.
- Put in a vacuum chamber, bring to 25 Hg/in pressure, and wait for 2 minutes to de-air. —OR— Let sit for 30 minutes to de-air.
- 6. If bubbles are present at top, use the mixing paddle to gently break them.
- Pour mixture into the mold or container containing the components to be encapsulated.
- Attention - Mixing >500 g [0.4 L] of Part B at a time into A decreases working life and promotes flash cure. Use of epoxy mixing machines with static stirrer recommended for large volumes. Limit size of hand-mixed batches.
To Room Temperature Cure The 834ATH Epoxy : Let stand for 24 hours.
To Heat Cure The 834ATH Epoxy :
- Put in oven at 80oC [176oF] for 60 minutes.
- Attention - Due to exothermic reaction, heat cure temperatures should be at least 25% below the maximum temperature tolerated by the most fragile
