It looked like a gimmick but the demonstrator was able to make a butt joint (tee) between two pieces of thin plastic with this system that I could not tear apart. He used the powder to create a fillet along the joint and this extra surface area dramatically increased the strength. As far as I can tell, the kit is a thin cyanoacrylate (CA) glue and the welding powder is fine glass beads. You put down a line of the powder along the joint and then drip on the glue. Basically it wicks into the powder and sets in a few seconds to a rock hard consistency. You can repeat this and actually build up to replace a tab or part that has snapped off as well as repairing. The final product can be filed or sanded and it is really tough. <\/p>\n<p>Where this excels is in fixing cracks in thin plastic or metal where there would not be enough surface area for conventional glue to hold. I have used this for all sort of toys and gadget repair. It is not a universal solution, but for certain applications, I have not found a substitute. I have seen some comments on Amazon that baking soda will work just as well, but I think the baking soda just causes rapid polymerization without giving the mechanical strength of the glass\/ceramic fill. <\/p>\n<p>A couple of caveats: <\/p>\n<ul>\n<li>This does not make a beautiful repair. The glass powder creates a lump along the seam a bit like a real weld. For some applications it doesn&#8217;t matter or you can hide this on the inner surface, but you are not getting a museum quality repair on the Ming vase. <\/li>\n<li>There are no safety warnings on the brand that I bought, but it seems prudent to be careful with the glass powder so you don&#8217;t get it (or the glue obviously) in your eyes.<\/li>\n<\/ul>\n<div class='ctx-module-container ctx_default_placement ctx-clearfix'><\/div><span class=\"ctx-article-root\"><!-- --><\/span>","protected":false},"excerpt":{"rendered":"<p>Repair breaks, cracks, holes and gaps<\/p>\n","protected":false},"author":76,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_mi_skip_tracking":false},"categories":[53],"tags":[],"acf":[],"_links":{"self":[{"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/posts\/32416"}],"collection":[{"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/users\/76"}],"replies":[{"embeddable":true,"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/comments?post=32416"}],"version-history":[{"count":1,"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/posts\/32416\/revisions"}],"predecessor-version":[{"id":32422,"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/posts\/32416\/revisions\/32422"}],"wp:attachment":[{"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/media?parent=32416"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/categories?post=32416"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/tags?post=32416"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
