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.
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.
"open time" has led to viewership numbers for key shows dropping as much as 70%.
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.
The amount of adhesive dispensed is determined by a combination of fluid flow rate and valve open time. An adjustable stroke control allows the flow rate to be fine tuned, and a microprocessor-based controller regulates open time.
Open time is the period after application when a coating surface is sufficiently wet to allow flow, release of solvents and air, and touching up without leaving marks.
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.
A current popular method for minimizing open time is a system developed and industrialized by REP.
For high strength steel bonding, Loctite H8500 Speedbonder structural adhesive offers a short open time, while Loctite H8510 Speedbonder structural adhesive offers an extended open time for parts alignment.
