ConTec AE-407


ConTec AE-407 is a liquid air-entraining admixture used to provide a suitable air-void system in concrete products. AE-407 is based on neutralized vinsol resin technology that is factory premixed into a ready to use solution for accurate dispensing.


ConTec AE-407 may be used wherever the need for air-entrainment is required by specification. AE-80 meets ASTM C 260 requirements designed for use in low slump and precast products. Concrete durability research has established that proper air entrainment can reduce the effects of freeze thaw cycles in hardened concrete. AE-407 is effective and compatible with other admixtures in concrete. AE-407 can be useful in production of “Slump Block”.


ConTec AE-407 is available in bulk quantities or packaged in 55 gallon (208 L) drums weighing 485 lbs (220 kg) and 265 gallon (1003 L) totes weighing 2400 lbs (1089 kg).

● Improves workability and plasticity.
● Helps reduce bleeding, segregation and shrinkage in concrete.
● Improves resistance to freeze thaw cycles.
● Improves water permeability.
● Greatly improves the properties of precast concrete when used in conjunction with SR-550.


ConTec AE-407 can be stored over a wide range of temperatures but should not be allowed to freeze. Should AE-407 freeze, allow complete thawing before mixing by mechanical means. AE-407 has a minimum shelf like of 12 months. With proper storage conditions the shelf life can be greatly extended.


The addition rates for AE-407 will vary depending on the mount of air needed for a given job condition. The components of mix design along with temperature are typical factors that effect the amount of AE-407 required. Consult your ICT representative for assistance.
