Product Name
Maven Epoxy EA 270 - Slow Set 60-80-Min Epoxy-Medium Viscosity Amber Clear-1:1 ratio
Brief Description
Maven Epoxy EA 270 is a two-part, toughened epoxy adhesive and potting compound featuring a slow set time of 60-80 minutes, medium viscosity, and an amber clear appearance. It mixes at a 1:1 ratio to produce a tough, flexible bond with high impact strength. This versatile epoxy is designed for a wide range of bonding, sealing, and encapsulation applications across various materials and industries.
Popular Applications & Uses
- Structural bonding of diverse materials including metals, plastics, ceramics, and rubber.- Potting, sealing, and encapsulation of sensitive electronic components such as transformers, coils, chokes, relays, glass diodes, and sensors.- Coating applications requiring a durable, clear, and protective layer.- Casting applications, especially for larger objects or where a controlled flow is needed.- Laminating for composite applications.- Repairs in automotive, marine (e.g., teak decks), and general manufacturing.- Countertop resurfacing and sealing.
Industries that Commonly Use It
- Aerospace/Defense for high-performance structural bonding.- Artist, Artisan for casting, coating, and crafting projects.- Automotive Service/Repair for durable bonding and repairs.- Cabinet & Woodworking for bonding and protective coatings on wood.- Construction/Building Services for general structural applications and coatings.- Concrete for sealing and protective coatings.- Countertop for durable and aesthetic surface finishes.- Electrical Services or Products and LED/Electronics for potting and encapsulation of components.- Fabrication, Metal Fabrication, and Plastic Fabrication for bonding various substrates.- General Manufacturing for a broad spectrum of adhesive and coating needs.- Marine for boat building, repairs, and bonding applications like teak decks.- Mold Making/Casting for creating durable casts.- Prosumer and Special Effects/Scenic Design for DIY projects, artistic creations, and set construction requiring a reliable, clear epoxy.- Transportation/Specialty Vehicle for structural bonding and component protection.
Special and Unique Features
- Slow set time (60-80 minutes work life) allows for extended adjustment and precise application, especially beneficial for complex assemblies or larger projects.- Medium viscosity provides a balance between flowability for good wetting and enough body for thicker coatings and vertical applications without excessive running or sagging.- Toughened epoxy formulation delivers a tough, flexible bond with high impact strength.- Low shrinkage upon curing, ensuring dimensional stability.- Good resistance to water, a wide range of chemicals, and many solvents.- Non-corrosive to copper, making it suitable for sensitive electronic components.- Excellent electrical insulation properties, even under high humidity conditions.- Minimal exotherm during curing, protecting heat-sensitive components.- Can be machined after full cure.- Optimized with UV inhibitors, anti-oxidants, and stabilizers for improved outdoor durability and color stability.

Comparison Note
Maven Epoxy EA 270 stands out with its extended 60-80 minute work life, offering significantly more time for precise positioning and complex assemblies compared to fast-setting epoxies (which can set in 3-10 minutes). Its medium viscosity strikes a balance, making it more suitable for thicker coatings, casting larger objects, and vertical applications where low-viscosity epoxies might run, while still providing good flow for wetting out surfaces. This product's toughened nature and resistance to various environmental factors also differentiate it from general-purpose or craft-grade resins, positioning it for more demanding industrial and structural applications.
