Engineered for faster cure speed —even at low temperatures— ANCAMIDE® 2861 delivers impressive early hardness development and outstanding water‑spot resistance. Its optimized balance of flexibility and strength makes it ideal for demanding metal primers and flooring applications. With its lighter color tone, low viscosity and favorable EHS profile, ANCAMIDE® 2861 offers formulators new freedom without compromise. Unlock the next level of performance for durable, resilient epoxy coatings.

This study introduces ANCAMINE® 2871 & 2872. These two ultra‑low‑emission epoxy hardeners that sharply reduce VOCs while maintaining strong adhesion, fast hardness development, and high carbamation resistance. Based on modified polyamines, the systems show much lower emissions than conventional hardeners. Standard tests confirm excellent curing and coating performance, providing a practical, low‑emission solution that meets labeling requirements.

Fast-cure floor coatings are essential for reducing downtime and increasing productivity, offering high performance, durability, and aesthetics. However, traditional fast-curing systems often compromise durability, UV resistance, adhesion, working time, and environmental, health, and safety (EHS) standards. ANCAMINE® 2880 is an innovative curing agent for epoxy systems that addresses these challenges. It combines rapid curing with excellent UV resistance, extended working times, and compliance with EHS standards. This solution enables a one-day flooring system, where both primer and topcoat can be applied and ready for use within 24 hours, even at low temperatures.

The ongoing impacts of climate change are reshaping our daily lives and significantly altering industry requirements. In these high temperatures, epoxy flooring applications face unique challenges as the temperatures influence the processing parameters of the coating formulations. ANCAMINE® 2858 is a newly developed curing agent for epoxy primers, specifically engineered for high-temperature climates.

Polyurethane coatings are valued for their flexible structure, but 2K systems face challenges like isocyanate toxicity, VOC emissions, and limited performance. Epoxy systems, while less flexible, excel in mechanical strength, chemical resistance, and low VOC formulations. This paper introduces ANCAMIDE® 2853 & 2865. These innovative flexible epoxy systems offer fast curing, high flexibility, sustainability, and superior adhesion, bridging gaps in current coatings.

Environmental regulations and safety demands have driven the development of low VOC coatings. HYBRIDUR® high-performance waterborne urethane-acrylic hybrid polymer dispersions (HPDs) offer superior mechanical properties and chemical resistance compared to PUDs and acrylic emulsions. This paper introduces NMP-free HPDs with an interpenetrating network (IPN) structure, delivering high performance, flexibility, and sustainability.
