TYPICAL PROPERTIES:

(Specification values available on request)

Base: EPDM rubber

Color: White

Solvent: Naphtha

Solids: 67%

Viscosity: Paste extrusion grade

Weight/gallon: 9.1 pounds

Specific Gravity: 1.09

Temperature range: -65°F to 210°F

PREPARATION OF SUBSTRATES:

Surfaces to be bonded should be cleaned of all dust, oils

or other contaminates. A solvent wipe is often adequate.

Bonds to rigid surfaces are usually improved by a solvent

wipe followed with light abrasion (180 grit) and solvent

wiping to remove abrasive residue. Dry surfaces thoroughly

before applying sealant.

METHOD OF APPLICATION:

DC12718 All Weather Sealant can be applied by ordinary

caulking guns or pressure pumping equipment. Pumping

equipment should be of the follower-plate type and have a

pump ratio of at least 40:1. Aro, Binks, Devilbiss, Graco and

Lincoln all produce satisfactory equipment for handling this

material.

Apply a bead of DC12718 All Weather Sealant to surface

at temperatures above 40°F. The applied bead will self level

and shrink approximately 30%, so no tooling is necessary

for most applications. The bead surface will be tack free in

15-45 minutes, depending on ambient conditions.

CLEANER AND THINNER:

Naphtha
