Key Features
✧ Extended pot life – The modified molecular structure provides a delayed reaction profile, allowing for longer working time and easier application of mixed material without compromising final cure.
✧ Excellent chemical and corrosion resistance – A high crosslink density and hydrophobic nature post-cure creates an impervious barrier against solvents, acids, alkalis, and salt spray, ensuring long-term substrate protection.
✧ Rapid dry-to-handle and through-cure – The amine technology facilitates a fast reaction with epoxy resins at ambient temperatures, enabling shorter downtime and faster return-to-service in industrial settings.
✧ Enhanced coating flexibility and impact resistance – The polyether backbone introduces flexible ether linkages (C-O-C) into the cured network, allowing the coating to absorb mechanical stress and deformation without cracking.
✧ Superior substrate adhesion – Strong affinity and wetting to various substrates, including prepared steel, concrete, and alloys, ensure a durable and long-lasting protective coating system.
✧ Good compatibility and easy blending – Designed for uniform miscibility with a wide range of epoxy resin types, facilitating homogenous film formation and consistent performance.
✧ Balanced mechanical properties – The curing agent promotes the development of a tough, abrasion-resistant film with an optimal balance of hardness and elasticity, ideal for demanding floor and corrosion environments.
✧ Effective performance at low temperatures – The active amine chemistry enables reliable curing and film formation even under challenging ambient conditions, extending the application season.
