Hychem E500P is designed as a pore filling primer to be used in conjunction with high build epoxy coatings and toppings to inhibit gassing of the high build product due to thermal movement of air between the substrate and the air space.
This pore filling action is essential when the surface is to be coated with any of the Hychem self-levelling epoxy toppings as well as the Hychem TL2, TL5, TL5 EPL, TL9 & TL9 high build epoxy tank linings.
