PRODUCT:         LOW VOLATILE AUTOMOTIVE SEALANT - BLUE

PART NOS:        47203, 49293

PRODUCT DESCRIPTION:

DynaGrip Low Volatile Automotive Sealant is a past like, one part material that cures to a tough rubbery solid upon exposure to moisture in the air. DynaGrip Low Volatile Automotive Sealant does not run thus making it ideal for use in either overhead or vertically. DynaGrip Low Volatile Automotive Sealant is formulated to meet or exceed OEM Volatility specifications for use near Engine Sensors.

PERFORMANCE PROPERTIES:

DynaGrip Low Volatile Automotive Sealant will not corrode or NOT adhere to Copper, Brass Magnesium, Zinc, Galvanized Metal. This sealant is NOT recommended for use on Brick, Masonry and Cement Type surfaces. During curing, product will emit an Acetic Acid type smell. DynaGrip Low Volatile Automotive Sealant has good resistance to weathering, vibration, moisture, ozone and extremes of temperature. It may be applied in sub-zero temperatures without the loss of extrusion or physical properties and is effective to –35oC. DynaGrip Low Volatile Automotive Sealant can withstand temperatures of 232oC and intermittently 260oC. At temperatures of 25oC, and a relative humidity of 50% a tack free skin will form in 20 minutes. Tooling should be complete in 5-10 minutes. Curing time increases with the thickness of the joint. Metal to metal bonds should not be more that 25mm. Adhered to glass, metals and most woods DynaGrip Low Volatile Automotive Sealant has a typical peel strength of 20lb/in2 after 72 hours curing at room temperature. When stored in a closed container at 32oC, DynaGrip Low Volatile Automotive Sealant has a shelf life of 12 months. Although an acidic odour is given off during curing, this will not harm oxygen sensors and will disappear after curing is complete.
