Experimental evaluation method of curing condition and shrinkage for UV curing adhesive

Curing with Shrinkage-Reducing Admixtures Beyond drying shrinkage reduction

Shrinkage of concrete, along with the cracking that often accompanies it, has been a continual concern of the concrete construction community.1,2 In the past 20 years or so, numerous shrinkage-reducing admixtures (SRAs) have been developed with the goal of reducing drying shrinkage and delaying or preventing cracking.2-6 Most SRAs function by reducing the surface tension of the pore solution in...

Characterizing the Efficiency of UV LED Curing

This paper examines the effects of some key operating parameters of UV sources on the curing of various UV inks, coatings and adhesives. The effects of peak UV wavelength and peak intensity are quantitatively evaluated using FT-IR. The data are helpful in guiding both formulators, raw material suppliers and end users to better understand the impact of the UV sources, especially UV LED sources, ...

UV-LED Curing Efficiency of Wood Coatings

Ultraviolet light emitting diodes (UV-LEDs) have attracted great interest in recent years. They can be used to polymerize coatings, such as those used for prefinished wood flooring. In this project, two lamps were compared for their suitability to be used on a wood flooring finishing line: a UV-microwave and a UV-LED lamp. Low heat emission was found for the UV-LED lamp compared to the UV-micro...
