Dowsil 888 Benefits

Can be extruded from -28.88 to 48.88°c.
May be used in joints that are not uniform in width.
Movement capability 100% extension and 50% compression.
Low modulus.
Weather and UV resistant.
Fuel resistant-short term exposure. Refer to Dow form number 62-207 for more information.
One component, cold applied, ready-to-use as supplied; dispensed directly from the bulk container into the joint by hand or with an air-powered pump.
Unprimed adhesion – primer is not required for bonding to Portland cement concrete. For optimum adhesion, the surface must be clean, dry and frost-free.
Cure time – typically, the sealant will have a skin-over time of one hour or less at standard conditions.

Dowsil 888 Joint Information

Joint width wide enough to accommodate movement. (For additional information on joint width, see papers by Spells and Klosowski, “Silicone Sealants for Use in Concrete Construction,” Vol. 1, No. 1, American Concrete Institute, SP-70, 1981; J.B. Cook, “Construction Sealants and Adhesives,” Wiley-Interscience, 1970; and J.M. Klosowski, “Sealants in Construction,” Marcel Dekker, 1989.).

Joint sawed deep enough to allow backer rod/sealant placement and space for pumping of old sealant compounds. NOTE: This applies to standard joints only; void space beneath backer rod in new construction is not needed.

Proper backer rod placement to prevent three-sided adhesion.
Sealant installed to proper depth and width.
Sealant recessed a minimum of 3/8 inch to 1/2 inch (9.53 mm to 12.7 mm) below pavement surface.
Depth of lowest slab determines the amount of recess required if grinding is anticipated; once grinding is complete, the sealant will have proper recess below the pavement surface.
