Maven EAF420 Off-White - Medium Set 20 Minute Epoxy Off-White - Toughened Temp Resistant 20-Minute Set Carbon Fiber, Plastic & Metal

Product Name

Maven EAF420 Off-White - Medium Set 20 Minute Epoxy Off-White - Toughened Temp Resistant 20-Minute Set Carbon Fiber, Plastic & Metal

Brief Description

Maven EAF420 is a two-component, room temperature curing epoxy adhesive known for its excellent toughness, flexibility, and strength. It is designed for structural bonding and can serve as a replacement for mechanical fasteners in many applications. This off-white epoxy offers a 20-minute working time, achieves handling strength in 1.5-2 hours, and fully cures within 24 hours. It is also electrically insulating.

Popular Applications & Uses

- Excellent bonder for Carbon Fiber (CFRP), Aluminum, Steel (ferrous and stainless), and various plastics.- Effective with ceramic, fiberboard, glass, rubber, and wood materials.- General bonding, gluing, potting, panel bonding, and structural bonding.- Quick repairs, fixing broken tools, repairing furniture, and automotive parts.

Industries that Commonly Use It

- Aerospace/Defense - for high-performance components and structural bonding where temperature resistance is critical.- Automotive Service/Repair - for bonding automotive parts and general repairs.- Fabrication - for general and structural bonding across diverse materials.- General Manufacturing - as a versatile, high-strength adhesive for various production needs.- LED/Electronics - due to its electrically insulating properties and potting capabilities.- Marine - for waterproof bonding and general repairs in boat accessories and structures.- Metal Fabrication - for bonding aluminum, steel, and other ferrous and non-ferrous metals.- Plastic Fabrication - for strong adhesion to a wide range of plastic materials.- Prosumer - suitable for craftsmen, DIY enthusiasts, and household repairs requiring professional-grade strength.- Transportation/Specialty Vehicle - for high-performance components and structural assemblies.

Special and Unique Features

- Toughened, providing superior shock and vibration resistance.- More flexible than many rigid epoxies.- Excellent temperature resistance, maintaining bond strength from -67°F to +300°F continuously, and up to 400°F for short durations (e.g., during powder coating processes).- Electrically insulating.- High shear strength (3500-4500 psi) and peel strength (40-60 piw).- 20-minute working time allows for precise positioning of parts.- Can effectively replace mechanical fasteners, screws, rivets, and spot welds.

Key Properties

- Two-component epoxy adhesive system.- Medium set with a 20-minute working life.- Cures at room temperature.- High viscosity, ranging from 30,000 cPs to 200,000 cPs depending on the specific formula.- Mix ratio of 2:1 (base to accelerator).- Shore Hardness of 35-40 Shore D.- 100% solids formulation, contributing to low odor and toxicity.

Surface Compatibility

- Carbon Fiber (CFRP)- Aluminum- Steel (ferrous and stainless)- Many Plastics- Ceramic- Fiberboard- Glass- Rubber- Wood
