EBECRYL® 3605

EBECRYL® 3605 is a partially acrylated bisphenol A epoxy resin, designed for applications requiring fast curing, improved flexibility, and superior adhesion to rigid, non-porous substrates. Here are some key details from the technical datasheet:

Introduction:

• EBECRYL® 3605 contains both acrylate and epoxy functionality, allowing it to cure via ultraviolet light (UV), electron beam (EB), or conventional two-part or thermal epoxy curing methods.
• It is particularly suitable for applications where a fast cure speed of an epoxy acrylate is needed, along with enhanced flexibility and adhesion properties.

Performance Highlights:

• Features a light color and possesses both epoxy and acrylate functionality.
• Exhibits good cure response, resulting in high gloss finish, good solvent resistance, high surface hardness, and excellent adhesion to metals and other non-porous substrates.
• Offers improved flexibility compared to conventional epoxy resins.

Suggested Applications:

• EBECRYL® 3605 can be used in a variety of applications, including coatings for metal substrates (such as aluminum), dual (UV/thermal) cure systems, and two-component curing systems.
• It can be applied using various methods including direct or reverse roll, offset gravure, metering rod, slot die, knife over roll, air knife, curtain, immersion, and spin coating methods, as well as offset and screen printing.
