OELS FROM SYSTEMS OF LOW VISCOSITY can be produced with C Y A N O C U M M I Gelling Agent. When introduced into cemei*t-sand mix tures, CYANOGUM i i will produce stiff gels in a predetermined timte. The photograph above SIIOAVS the difference in gelation between an unmodi fied cement-sand mixture, left, and one gelled by CYANOCUM 4 1 , right, after 5 minutes elapsed time. In concrete aggregates, latex, and in dis persions of solids, shorter gel times may improve the economics of manu facture of molded or cast products. CYANOGUM 41 can be placed and gelled virtually anywhere that water can be introduced. ( M a r k e t Development- D e p a r t m e n t )
