Interface agent is a kind of adhesive generally made of vinyl acetate ethylene. It has strong adhesive ability, excellent water resistance and aging resistance as well. Improving the bonding strength of plastering mortar to the base can effectively avoid the problems of hollowing, falling off, shrinkage and cracking of plastering layer.

It is used to treat the surfaces of concrete, aerated concrete, lime sand brick and fly ash brick, and solve the problem that the interface is not easy to bond due to strong water absorption or smoothness of the surface, resulting in hollowing, cracking and peeling of the plastering layer. It can greatly enhance the adhesion between new and previous concrete and also between concrete and plastering mortar.

It can replace the traditional roughening process of concrete surface and improve the plastering process of aerated concrete surface. It is an indispensable supporting material for modern architecture and decoration construction. However, vinyl acetate ethylene liquid generally has no viscosity. When customers use it, because it is not viscous, it has poor fluidity, and the amount of use will increase, resulting in some unnecessary waste.

EPAM interfacial agent is a high molecular polymer emulsion, which can effectively increase the consistency of the interfacial agent, at the same time, it has good compatibility and compatibility with the cement, and does not appear the phenomenon of cement seepage, and has good stability.
