Features Of Modified Cycloaliphatic Amine Curing Agent WK-4028

  1. Enhanced pot life compared to standard cycloaliphatic amines, enabling extended processing window for large-scale casting and laminating.

  2. Low exotherm profile ensures reduced thermal stress and minimized risk of cracking in thick-section epoxy formulations.

  3. Excellent adhesion to diverse substrates including metals, composites, and concrete without primer requirement.

  4. Improved moisture tolerance during cure, supporting reliable performance under ambient humidity conditions (up to 80% RH).

  5. Non-blushing formulation prevents surface haze or amine carbamate formation in high-humidity environments.

Typical Applications Of Modified Cycloaliphatic Amine Curing Agent WK-4028

  1. High-performance epoxy flooring systems for industrial and pharmaceutical cleanrooms.

  2. Electrical insulation castings for transformers, bushings, and encapsulated power electronics.

  3. Structural adhesive formulations requiring low shrinkage and high Tg after cure.

  4. Wind turbine blade bonding and composite repair matrices.

  5. Marine-grade protective coatings and underwater repair compounds.
