Loctite Prism 4500 series next generation cyanoacrylate adhesives offer exceptionally fast cure speeds. Also, over the product's 21 month shelf life, cure speed will not degenerate measurably. The adhesives are less responsive to environmental variables such as humidity and temperature. This overall product stability results in improved quality, easier process control, more reliable and precise dispensing, consistent process throughput, reduced scrap, simplified inspection, and lower overall cost.
