AE-86 water-based permeable crystalline base interface agent is made of polymer modified emulsion asphalt. It is a base treatment agent for a universal asphalt-based waterproof system, mainly used for base treatment before the construction of thermal melt, self-adhesive asphalt coil or asphalt coating.It can effectively improve the bonding force between the waterproof layer and the base layer, improve the adaptability of the waterproof layer to the base layer for expansion or contraction due to temperature changes, and at the same time has the function of sealing the mortar base capillary holes and blocking water vapor penetration.
