<br />Product Description
<br />E-Curb penetration seals replace old-style metal pitch
<br />pans with versatile, precast components and pourable
<br />sealants. CHEM LINK’s E-Curb System can usually
<br />be installed in under 15 minutes and never requires
<br />flashing or mechanical attachment.
<br />E-Curbs are designed for use on granulated modified
<br />bitumen, asphalt and coal tar B.U.R. (built up roofing).
<br />E-Curbs are specified for PVC, EPDM, PIB, and TPO
<br />single ply roofing membranes. E-Curbs are highly
<br />versatile for sealing penetrations around solar panel
<br />mounts, HVAC, Electrical, and any type of structural
<br />supports. TPO Primer is required for use with TPO
<br />single-ply roof membrane.
<br />When installed properly, this system forms a durable,
<br />waterproof rubber seal around penetrations. An
<br />extended manufacture warranty against leaks is
<br />activated with submittal of a completed warranty card.
<br />Special Characteristics
<br />•Rapid installation - “Slip-fit” light weight curb design
<br />reduces labor significantly.
<br />•Excellent adhesion to most roofing materials.
<br />•No flashing or mechanical attachment required.
<br />•Service Temperature -40°F to 200°F (-40°C to 93°C)
<br />•1-Part ® accommodates movement and is suggested
<br />for use on all granulated membranes and details
<br />with excessive movement.
<br />•For sloped roof applications, substitute DuraLink 50™
<br />non-slump adhesive/sealant for 1-Part and M-1®
<br />E-CURBTM SYSTEM
<br />PENETRATION SEALS
<br />Restrictions
<br />•Please contact customer service for application
<br />guidelines with temperatures below 32°F (0°C).
<br />•Do not install if rain is anticipated within 4 hours.
<br />•Do not use on Hypalon or smooth APP modified
<br />bitumen membrane. For smooth APP, torch down
<br />a target of granulated APP before installation.
<br />•TPO Primer must be used for TPO applications.
<br />•Do not prime bonding surfaces with asphalt primer!
<br />•Do not use asphalt cement as a “night sealant.”
<br />Use M-1 for this purpose.
<br />•E-Curb kits are designed to contain enough 1-Part
<br />to fill each curb with displacement in consideration.
<br />Refer to our penetration calculator under contractor
<br />resources at chemlink.com to verify volumes.
<br />E-Curb System Components
<br />•E-Curb exterior rings, straights, and corners.
<br />•M-1 Structural Adhesive/Sealant used for bonding
<br />the E-Curb components, sealing and priming the
<br />penetration.
<br />•1-Part “moisture cure” pourable sealer, used to
<br />form a durable, water-tight seal around the roof
<br />penetration. US Patent No. RE41,586
<br />E-Curb precast form components are composed of light
<br />weight nylon resin. The E-Curb is 2-inches high and is
<br />available in a variety of shapes and sizes.
<br />Standard sizes include bisected circular pieces with
<br />inside diameters of 3, 4, 5, 6 or 9 inches; corner pieces
<br />with a 2-inch radius; straight pieces in 3-inch or 8-inch
<br />lengths; and a 4.5” x 3.4” rectangle. The outer surface
<br />is impervious to ice, corrosion, UV (ultraviolet) light and
<br />ponding water.
<br />M-1 Structural Adhesive/Sealant is a durable, self-
<br />fixturing moisture cure mastic. Cartridges of M-1 are
<br />supplied in each E-Curb Kit. Components are also sold
<br />separately.
<br />1-Part is a highly flexible, self-leveling moisture cure
<br />pourable sealer that eliminates mixing. It is also 100%
<br />solid rubber, has a very low VOC content, will not melt
<br />or shrink, and is resistant to deterioration. It is supplied
<br />in 10.1-oz and 28-oz cartridges or 1/2 gallon pouches.
<br />Unused sealant can be capped and reused.

<br />POLYMER INNOVATION
<br />Step 1
<br />Remove all previously applied caulk, mastic, cement,
<br />asphalt, and other contaminants from penetrations
<br />with a wire brush. Clean all smooth substrates with
<br />isopropyl or denatured alcohol. Brush away all gravel
<br />or loose granules. Seal the base of each penetration
<br />with M-1. Coat penetrations with M-1 to 3” above the
<br />roof line.
<br />Step 2
<br />Hold a section of E-Curb, flat side up, and apply
<br />a 1/4” bead of M-1 to the entire bottom perimeter.
<br />Apply 1 additional 1/4” bead of M-1 down the center
<br />of the section. Do not tool the beads flat. Place the
<br />E-Curb section on the roof surface to form a half circle
<br />around the penetration(s). Press down firmly until M-1
<br />extrudes from the outside edges.
<br />Step 3
<br />Apply M-1 to the second section of E-Curb as described
<br />above. Place the second section of curb on the roof
<br />surface to form a circle with the first section. Press
<br />firmly in place until excess adhesive extrudes from the
<br />outside edges. Apply a bead of M-1 around the outside
<br />base of the installed E-Curb, and tool to form a smooth
<br />fillet. For non E-Curb penetrations seals, add M-1 to
<br />scarf joint surfaces and tool smooth.
<br />Step 4
<br />Cut tip off 1-Part cartridge at widest point on plastic
<br />nozzle and pierce the foil seal. Insert into caulking gun
<br />and pump E-Curb full. When using a 1-Part pouch,
<br />remove cap, pour, squeeze out excess air, and reseal.
<br />Note: To provide an adequate rubber seal, maintain a
<br />1” distance between penetrations and inside edge of
<br />the E-Curb.
