Evonik Industries (EVK) Status Update summary

Market needs and product development

• Flexible epoxy systems are in demand for applications like concrete protection, waterproof membranes, and adhesives, requiring high elongation and toughness.

• Existing technologies like urethanes and polyureas offer flexibility but have handling and environmental drawbacks, while standard epoxies lack flexibility.

• Market drivers include enhanced performance, efficiency, and eco-friendly profiles, with a focus on high flexibility, fast cure, and absence of substances of high concern.

Product features and performance

• Two new curing agents, Ancamide 2853 and 2865, were developed to address unmet needs, offering high elongation, toughness, and nonylphenol-free formulations with bio content.

• 2853 provides higher elongation and viscosity, while 2865 offers lower viscosity and lighter color; both allow adjustment of strength and flexibility by changing mix ratios.

• Both products demonstrate fast cure times, high tensile and tear strength, and maintain flexibility and strength at low temperatures.

• Flexibility and recovery are retained after stretching and heating, with minimal loss in performance after repeated deformation and exposure to temperatures up to 70°C.

Regulatory, availability, and sustainability

• Both products are nonylphenol-free, contain 40% (2853) and 20% (2865) bio content from natural resources, and have a typical shelf life of 24 months.

• Products are available in most countries except Europe (pending REACH registration), are made in the continental U.S., and samples are available upon request.

• EHS profile is typical for amine curing agents, with no health hazard pictogram, and both products are designed for sustainability and eco-friendliness.
