Dark Brown / Black
Applied by Trowel /Putty Knife
Skinning : 2 to 3 hours Through Dry : Non-Drying
Used as a vapor barrier sealant for sealing insulation joints and as a bedding compound for protecting cellular glass and urethane foam board stock insulations from abrasion.
Primarily used with low temperature insulation to prevent migration of water and water vapor into the insulation system via butt joints.
Remains soft, flexible and in-tact in joints without cracking or shrinking under repeated thermal cycles preventing damage to the insulation.
Performs well under condensing and humid conditions to protect equipment from corrosion breakdown and reduces outrageous upkeep costs. Does not contain hazardous compounds of lead and mercury.
Can be used over wide operating temperature range. Its trowel consistency facilitates application to insulation surfaces without stringing or excessive drag.
