Instant Glue from Green Stuff World is a single component cyanoacrylate glue that is advertised to set in 5–10 seconds. In my use, I found the glue to set almost instantaneously. The glue is best used with dissimilar materials including plastic, photoetch, rubber, metal, wood, and ceramics. When dispensed, the adhesive quickly reacts with the moisture in the air, so drying time is affected by humidity. In drier climates, the glue will take longer to set. The glue sets so quickly that I found it best to hold the parts together in the correct position and then apply the glue. Applying glue to the parts and then placing them does not allow any time for positioning. The CA glue seems strong as I did not have any problems with photoetch parts coming loose after the glue set.

The review sample came with a package of 20 Green Stuff World Glue Tips for CA Bottles ($3.11) https://www.greenstuffworld.com/en/glue-tips/52-super-glue-precision-tips.html I have used tips like these from other manufacturers, and find them indispensable when working with CA glues. The GSW tips have a nice, pointed tip that is stiffer than others I have used. The tips have a narrow opening for precise application of the glue, and the glue is visible in the tip, so you know when it is coming. The tip opening is small enough that it can be left on without a cap, and this does not seem to affect drying of the glue in the bottle. If the glue dries at the tip, it can be pulled off, the tip drilled out, or a small piece cut off to open the flow again.

Green Stuff World’s CA Glue Activator was also provided, but unfortunately the bottle leaked during transit and there was very little remaining. The Instant Glue set so quickly that I did not need to use the accelerator.

Green Stuff World’s Instant Glue worked very well as a quick-setting CA glue. The CA Glue Bottle Tips are an excellent accessory for GSW and other CA glue bottles. Thanks to Green Stuff World for providing the review samples.
