S33905 6 Inch Diameter QWIKDOT
S33906 8 Inch Diameter QWIKDOT
Crafco QwikDots are peel and stick pressure sensitive polymer modified asphalt adhesive round pads used for adhering delineator posts, rumble strips, parking bumpers, temporary sign posts, temporary markers or other items to both asphalt concrete and portland cement concrete pavement surfaces.
QwikDots are supplied in two sizes, either 6 inch (15cm) diameter with 120 per box or 8 inch (20cm) diameter with 80 per box. QwikDots are sold by the box.
Crafco QwikDots meet the following requirements:
TESTS SPECIFICATION LIMIT
Softening Point (ASTM D36)* 225°F (107°C) Min
Flexibility 90° Bend, 1" (25mm) mandrel (ASTM D3111) Pass at -30°F (-34°C)
Cone Penetration, 77°F (25°C) (ASTM 5329)* 50 max.
Elongation 77°F (25°C) 1000% min.
Opening to Traffic Time Immediate
* NOTE: These tests require heating QwikDots to 350°F (177°C) according to ASTM D5167 to prepare the test specimens.
INSTALLATION
Prior to use, all persons involved with installation shall read the MSDS for QwikDots and follow the listed safety requirements. Pavement surfaces must be clean and dry prior to installation. Surfaces should be blown clean with high pressure clean, dry, oil free air at a minimum pressure of 90 psi (62 kpa) to remove all dust, dirt, or other contaminants. Minimum pavement temperature for installation is 70°F (21°C), and minimum air temperature is 40°F (4°C). If pavement or air temperature is less than 70°F (21°C), the pavement surface is to be warmed with a torch or heat lance.
The QwikDot used should be slightly larger that the base of the item being adhered. For long items, such as parking bumpers, a minimum of 2 QwikDots should be used, placed at a maximum spacing of 12 inches (30cm).
To install, the QwikDot is placed onto the pavement surface with the adhesive side down. After the QwikDot is applied, and with the release liner still on the top surface, apply pressure to the QwikDot to establish adhesion. The release liner is then removed to expose the upper adhesive surface.
If temperature is below 70°F (21°C), the top surface of the QwikDot is to be lightly warmed with a heat lance or torch (approx. 2-5 seconds), and then the item being adhered is immediately placed by pressing it firmly into the QwikDot.
If temperature is above 70°F (21°C), warming is not required, but may be done for improved adhesion.
