Q1: What is the primary function of Aradur 115X70 in epoxy formulations?
A: Aradur 115X70 is a liquid polyamide-based curing agent solution designed to react with epoxy resins—particularly bisphenol A and bisphenol F types—to form crosslinked thermoset networks. It enables ambient- or low-temperature cure while delivering good flexibility, adhesion, and chemical resistance.
Q2: Is Aradur 115X70 compatible with standard industrial epoxy resins?
A: Yes, Aradur 115X70 is formulated for broad compatibility with common liquid and solid epoxy resins used in coatings, adhesives, and composite applications. Compatibility and optimal performance should be verified experimentally for each specific resin system and end-use requirement.
Q3: How does the solvent content in Aradur 115X70 affect formulation handling and film formation?
A: As a solution-grade curing agent, Aradur 115X70 contains solvents that improve viscosity control, mixing efficiency, and pot life stability. The solvent type and level are selected to support uniform dispersion and minimize volatiles-related defects during cure—though final film properties depend on complete solvent release and full crosslink development.
Q4: Can Aradur 115X70 be used in high-solids or low-VOC coating systems?
A: Aradur 115X70 was developed with attention to modern regulatory and performance expectations, including suitability for high-solids formulations. Its solution format allows for flexible VOC management, though final compliance depends on the full formulation—including resin choice, co-solvents, and additives—as well as application and cure conditions.
