Epi-cure 3274 Aliphatic amine Hexion Specialty Chemicals North America South and Central America Crosslinking / Coupling / Curing Agents >> Amine Epoxy Resins Architectural / Decorative >> Flooring EPI-CURE™ Curing Agent 3274, a moderately reactive, low viscosity aliphatic amine, is water insensitive and resists "blushing" "bloom" and "sweat-out" in epoxy compositions cured in high humidity environments. Other features are light color, improved color retention as compared to conventional amine cured epoxy systems, and long pot life. Glaze and sealer high-build coatings for decorative flooring Possessing excellent compatibility with liquid epoxy resins, EPI-CURE Curing Agent 3274 does not require an induction period to produce cured glossy surfaces even under adverse humidity conditions. Due to the great difference in viscosities between this curing agent and most liquid epoxy resins, thorough blending may take longer than usual to achieve. A mixing period of 2 or 3 minutes is usually adequate to ensure a homogeneous solution of resin and curing agent. Flow control agents such as urea-formaldehyde resin, colloidal sili-ca, SR-82 silicone resin 1 , Modaflow flow control agent 2 or various thixotropes should be incorporated into high-build coatings to ensure good film continuity. Cure rate is proportional to temperature and application thickness. For 5 mil films of EPON ™ Resin 828/ EPI-CURE 3274 systems, tack-free cure is obtained in approximately 12 hours at 25 °C. Incorporation of flexibilizers such as HELOXY ™ Modifiers 32 and 505 or monoepoxide diluents generally extend the working life and lengthen the cure period required. If increased reactivity is desired. EPI-CURE Curing Agents 3270 or 3271 may be blended with EPI-CURE 3274. Moderately reactive, low viscosity aliphatic amine. Used in glaze and sealer high-build coatings for decorative flooring. Offers water insensitivity and resistance to "blushing", "bloom" and "sweat-out" in epoxy compositions cured in high humidity environments. Provides mproved color retention and long pot life. Possesses very good compatibility with liquid epoxy resins.
