Dow DER 755 Aliphatic Epoxy Resin

Dow DER 755 is a low-viscosity aliphatic epoxy resin from Dow’s DER™ series, offering excellent UV stability, color retention, and weather resistance. Ideal for coatings, adhesives, and composites requiring long-term clarity and durability. It cures with amines or anhydrides, delivers low exotherm, and enables easy processing. Widely used in aerospace, automotive, and optical applications due to its superior hydrolytic stability and low yellowing tendency.

Features Of Dow DER 755 Aliphatic Epoxy Resin

  1. Aliphatic structure provides excellent UV stability and superior resistance to yellowing.

  2. Low viscosity enables easy handling, efficient mixing, and improved wetting of fillers and substrates.

  3. High epoxy equivalent weight supports formulation flexibility for low-reactivity, extended pot life systems.

  4. Excellent chemical resistance to alkalis, solvents, and mild acids in cured form.

  5. Compatible with a broad range of aliphatic and cycloaliphatic amine hardeners for ambient or elevated cure profiles.

Typical Applications Of Dow DER 755 Aliphatic Epoxy Resin

  1. UV-stable clear coatings for architectural concrete and decorative flooring.

  2. High-gloss, non-yellowing protective topcoats for marine and transportation composites.

  3. Electrical encapsulants and potting compounds requiring long-term color retention.

  4. Adhesives for bonding glass, metals, and plastics in outdoor-facing assemblies.

  5. Formulation base for high-performance, low-VOC industrial maintenance coatings.
