Maven EA 270BK Black Epoxy Adhesive & Potting Compound - Slow Set 60-80-Min Epoxy-Medium Viscosity Black-1:1 ratio

Product Name

Maven EA 270BK Black Epoxy Adhesive & Potting Compound - Slow Set 60-80-Min Epoxy-Medium Viscosity Black-1:1 ratio

Brief Description

A two-part, slow-setting, medium-viscosity black epoxy adhesive and potting compound with a 1:1 mix ratio, designed for robust bonding and comprehensive protection of sensitive components. It offers a long working time for precise applications and cures to a tough, machinable bond with high impact strength.

Popular Applications & Uses

- Encapsulating and protecting electronic components and circuit boards from environmental factors, vibration, and thermal shock.- Sealing and potting electrical connections, sensors, transformers, coils, chokes, and other heat-sensitive components.- Structural bonding of a wide range of materials including metals, plastics, ceramics, and wood.- General assembly applications where a longer working time is beneficial for precise placement, alignment, or covering larger areas.- Applications requiring high impact strength and excellent resistance to water, a wide range of chemicals, and many solvents.

Industries that Commonly Use It

- Aerospace/Defense- Automotive Service/Repair- Chemical Industry- Construction/ Building Services- Electrical Services or Products- Energy (e.g., renewable energy, photovoltaic)- General Manufacturing- Government & Military- Industrial Supply- LED/Electronics- Marine (e.g., marine electronics, vessel repair)- Medical Device/ Prosthetics (due to resistance to medical sterilization)- Metal Fabrication- Plastic Fabrication- Transportation/ Specialty Vehicle (e.g., commercial transportation, heavy machinery)

Special and Unique Features

- Slow set time of 60-80 minutes, providing extended workability for complex assemblies or precise positioning.- Medium viscosity, allowing for good flow and gap-filling capabilities without excessive run-off.- Black opaque color, which can be used for aesthetic purposes or to secure intellectual property by obscuring internal components.- Convenient 1:1 mix ratio for easy and accurate preparation.- Non-corrosive to copper, making it suitable for sensitive electrical and electronic components.- Exhibits low shrinkage and minimal exotherm during the curing process.- Machinable once fully cured, allowing for post-cure finishing.

Known backups / known substitutes

- 3M DP270BK Black potting compound is a popular direct substitute.- Other general-purpose black epoxy potting compounds with similar work life and viscosity, such as MG Chemicals 832B or 832FX, could be considered depending on specific requirements.- For applications requiring more flexibility, urethane or silicone potting compounds might be alternatives, though they offer different mechanical strengths and temperature resistances.- For temporary or less critical applications, neutral-cure silicone or hot glue have been mentioned as makeshift alternatives, but they do not provide the robust, long-term protection of epoxy.

Comparison Note

The Maven EA 270BK distinguishes itself with an extended 60-80 minute work life, offering significantly more time for intricate assembly, precise component placement, or large-area applications compared to faster-setting epoxies. Its medium viscosity provides a versatile balance, ensuring good flow for potting while maintaining sufficient body for adhesive tasks. As a two-part epoxy, it delivers superior mechanical strength, chemical resistance, and electrical insulation, making it a robust choice for demanding environments, though it offers less flexibility than silicone or urethane alternatives. The opaque black finish is a specific feature, useful for aesthetics or for concealing sensitive internal components.
