Bonding is a sticking point for some instant superglues
Some instant superglues may not be as sticky as they're made out to be.
While most work well on most materials, some are not effective in bonding metal and leather, despite claims they can do so, the Consumer Council says.
The council urged consumers to be wary of all advertising claims about instant glues, and to check the performance of the glues on the materials they wanted to use them on before buying.
Eight of the 10 samples tested were said to work on leather products but two were found far from effective in sticking pieces of leather together. Three samples were judged to be just fair in gluing metal and one performed comparatively poorly with such materials.
The test revealed most instant-glue samples in the test could strongly bond wood, glass, polyvinyl chloride and polystyrene.
One sample, with only labelling in Japanese and no Chinese or English, was referred to the Customs and Excise Department for follow-up action. The council tested 10 samples of instant glues on performance, durability, the appearance of the bonded material, ease of use and product labelling.
Seven materials - wood, metal, glass, polyvinyl chloride, polystyrene, leather and rubber - were put through a series of stringent tests.
