298E Elastomeric Asphalt Emulsion is an asphaltic bentonite clay emulsion modified with acrylic rubber to achieve a permanently elastomeric waterproofing compound and surface coating. When cured, 298E Elastomeric Asphalt Emulsion resists checking and cracking. The dry film remains flexible and will not sag, flow or re-emulsify. Special unblown soft asphalts help improve the weathering characteristics of #298E Elastomeric Asphalt Emulsion as well as enhance resistance to industrial pollutants, contaminants and corrosives. Premium acrylic rubbers increase the elongation of 298E Elastomeric Asphalt Emulsion and also give it greater adhesion and low temperature flexibility.
