Q1: What is the primary function of EPIKOTE 874-L-X90 in waterborne coating systems?
A: EPIKOTE 874-L-X90 functions as a reactive epoxy dispersion that serves as a key binder or crosslinker component in high-performance waterborne industrial coatings, providing enhanced chemical resistance, adhesion, and film integrity without requiring organic co-solvents.
Q2: Can EPIKOTE 874-L-X90 be used with common waterborne amine hardeners?
A: Yes — it is specifically designed to react efficiently with standard waterborne polyamine hardeners, including aliphatic and cycloaliphatic types, enabling ambient- or low-bake cure profiles while maintaining colloidal stability during formulation and storage.
Q3: How does EPIKOTE 874-L-X90 compare to solvent-based epoxy resins in terms of VOC content and regulatory compliance?
A: As a true waterborne dispersion, EPIKOTE 874-L-X90 contains negligible VOCs and supports formulators in meeting increasingly stringent global environmental regulations for low-VOC industrial coatings, without compromising on cured-film performance attributes.
Q4: Is pre-dilution or pH adjustment required before incorporating EPIKOTE 874-L-X90 into a coating formulation?
A: The resin is supplied as a stable, ready-to-use dispersion with optimized pH and rheology; no mandatory pre-dilution or pH adjustment is needed. However, compatibility testing with other formulation components is recommended to ensure long-term stability and performance consistency.
