ChangFu® EPO32: A Newly Upgraded Coupling Agent – Flexible Interface Solution for High-Stress Scenarios.

In applications involving high stress, high deformation, or extreme thermal cycling, rigid interfaces often become new weak points, hindering product development. ChangFu Chemical introduces ChangFu^® EPO32, which innovatively incorporates ether-bond flexible segments into its molecular chain. This product not only retains the strong dual bonding capabilities of traditional silane coupling agents but also provides the interface with greater flexibility and stress-buffering capacity. It is suitable for coatings, adhesives, and composite materials with demanding performance requirements.

Product Features:

l  Excellent Chemical Resistance:

The flexible interface maintains better integrity, enhancing the chemical resistance of coatings or composites.

l  Enhanced Flexibility:

The ether-bond flexible segments act as a superior "flexible bridge," alleviating internal stress caused by differences in thermal expansion coefficients and significantly reducing interface brittleness.

l  Superior Adhesion Promotion:

With more efficient and flexible crosslinking capabilities, it achieves deeper and more durable bonding strength.

l  Outstanding Compatibility and Stress Dissipation:

The longer flexible chain segments improve compatibility and diffusion in complex resin systems (especially high-viscosity or low-polarity systems), enabling more uniform coating of fillers or fibers and achieving ideal interface modification.

Applicable Fields:

1.       High-Performance Fiber-Reinforced Composites:

u  Significantly improves interlayer toughness and fatigue resistance, extending product service life.

u  Ideal for aerospace and automotive sports components require high strength while enhancing interlayer toughness and impact resistance.

2.       Extreme Environment Coatings and Protective Coatings:

u  The flexible interface layer greatly enhances coating durability on flexible substrates.

u  Suitable for protective coatings in environments with extreme temperature variations, requiring excellent resistance to thermal cycling and delamination.

3.       High-Performance Elastic Adhesives:

u  Significantly improves the durability of adhesive systems under dynamic loads, preventing bonding failure due to stress fatigue.

u  Ideal for selling and bonding applications require vibration resistance, deformation tolerance, and high bonding strength.
