However, this is not always true of latex paints, where control of open time has been the focus of much research and product development, especially with the move to low- and zero-VOC products.
In the end product, the new dispersible polymer powder ensures a long open time and enhanced flexibility combined with excellent tensile adhesion strength, even after water or freeze/thaw conditions.
Their excellent hot tack properties allow them to adhere quickly while providing up to 40 seconds of open time to meet production requirements.
TAMS ratings for the first two weeks after the closure of open time compared with the previous two weeks demonstrate viewership falling from nearly a million for M-Net's flagship daily soap "Egoli" to roughly 285,000.
A combination of fluid pressure, flow rate and valve open time determines the amount of fluid dispensed, and a microprocessor-based ValveMate controller regulates the open time.
For high-strength bonding, H8500 offers a short open time, while H8510 provides an extended open time for parts alignment.
This is said to enable a fine-tuning of the bonding process, with the possibility to adapt the initial strength, open time and rheological characteristics to the specific requirements over a relatively broad range.
Mounted near the valve, the controller is designed to simplify system setup and allows open time to be adjusted in increments from 0.
However, the open time or wet-edge time of low/zero-VOC aqueous coatings is a major challenge during application when cosolvents or coalescing agents are eliminated from the formulations.
Rhodia has introduced Rhodoline OTE, APE-free and zero-VOC additives that extend waterborne coating open time two to four fold and enables the formulation of highly performing low- to zero-VOC coatings.
Proform 3640, with a short-to-moderate open time of 20 to 40 seconds, has been engineered to resist temperatures as high as 165[degrees]C.
