Superglue is VERY strong, definitely stronger than hot glue.
What glue is better than hot glue?
Typically, the harmful chemicals in these products are the liquid solvents. These solvents allow the adhesives to remain liquid in the container and evaporate as the product hardens. Many of these solvents are flammable and toxic. Common adhesive solvents to avoid are hexane and toluene.
Why is glue toxic?
Yellow glue was introduced with a bit of coloring in it to distinguish it as a higher quality product. Typically, it has a higher solids content, is a bit thicker, and often has a faster tack time. None of these issues has much of anything to do with strength, but rather of handling properties.
Why yellow glue is stronger than white glue?
If glue is accidentally dried on the skin, it will not cause poisoning. It may just take some time for it to completely wear off. If the glue gets in the mouth, the liquid becomes a solid very quickly and can cause choking.

“Our current adhesives create all sorts of environmental problems,” Wilker said. “Almost all glues are petroleum-based and do not degrade. The bonded materials in our products stay stuck together. Consequently, we cannot recycle many of the materials that we put into our recycling bins.
Why is glue not sustainable?
Without moisture the adhesive will not feel 'sticky' or cure, leading to project failure. For best results follow the pack directions 'Damp It, Glue It, Grip It' – apply a small amount of moisture to one surface, then apply glue to the dry surface and clamp.
