APR. 20. 2006 12:18PM f -- INFRATECH 7634286489 NO. 906 P. 2 Sauerelsen Manhole ChimneySeal No. F -88 is an elastomeric lining com- posed of fiber - reinforced, asphalt -modi- fied urethane. ChimneySeal is used as a chemical- resistant membrane or gasket seal for the prevention of water Infiltra- tion. Manhole ChimneySeal has excellent adhesion to most substrates. As a high solids eiastomer, it is recommended when movement from temperature change or other causes will be encoun- tered. Manhole ChimneySeal maintains excel- lent elasticity and adhesion over a tem- perature range of -300F to 250 °F. The flexible barrier resists freeze/thaw stress- es and movement. When subjected to mechanical stress, the lining has nearly 100% recovery. Manhole ChimneySeal also resists alkalies, salts and acid ItHARACTERISTICS o Outstanding chemical resistance to acids and alkalies. a Remains flexible from -30 °F to 250 °F. o Easy to apply by hand. o Urethane -based elastomer. o Suitable for application on steel, brick or concrete substrates. o Excellent elasticity. AREA PREPARATION Temperature of Working Area Maintain an optimum temperature of 60° - 85 °F on air, substrate and material dur- ing mixing, application, and cure. Store material In the range of 65° - 80 °F for at least 48 hours before use, Surface Preparation urfaces should be made free of oil, ase. water, and other contaminants at may inhibit bond. This can be achieved by chemical deaning. ilk WI SAiJtiwIbN FN MANHOLE CHIMNEYSE1 ,L NO.

Actual field conditions may vs! ,' and yield different results; therefore, data are subject to reasonable deviation. Brick - The working substrate must be dry and firm enough to withstand Imposed loads during normal operation. Mechanical methods should be utilized to remove old paints, coatings, and deterio- rated mortar or brick. Abrasive blast or high - pressure water blast brick to obtain a uniform, sound substrate. All prepared surfaces must be allowed to dry prior to the Manhole ChimneySeal application. Concrete - The working substrate must be dry and have the necessary strength to withstand imposed loads during normal operation. For applications where Manhole ChimneySeal is recommended. All voids should be filled with Sauerelsen Underlayment No. F -120 or Filler Compound No. 209. The choice of under - layment will depend on the severity of the voids to be filled. Abrasive blast or high - pressure water blast concrete to remove laitance and to obtain a uniform surface texture exposing fine aggregate resembling coarse sand- paper. Regardless of preparation method used, all surfaces must be free of any loose deposits or contamination. Metal - Abrasive blast or mechanically abrade the metal surface to a nominal 2.5 mil profile employing a SSPC -SP 8 Commercial finish. All protrusions should be ground smooth to eliminate sharp edges. APPLICATION Mixing Packaging consists a tlzed containers of H; Resin Part B. Comi tents of Hardener Pa; 9.

SETTING /CURIN Ili Curing of the Chimne !Seal lining is by chemical reaction. While Manhole ChimneySeal has an E :proximate work- ing time of 45 minutes initial set occurs In about one hour at 70 °F. Manhole ChimneySeal cures to 1 semi -soft, elas- tomerlc state. Protect t le installation site from water or chemical I prior to cure for 48 hours.
