As an industrial and scientific product user we have experimented with various plastic welding adhesives and finally settled for this one .Based on our own experience, this gray-colored TPO plastic welding solution provides seamless welding on TPO (thermoplastic olefin) materials that are commonly found in automotive and industrial equipment. Moreover, it is easy to apply and bonds instantly without leaving any gaps. The only downside we found is that it requires a consistent and slow speed while applying the adhesive, which can be time-consuming. Overall, it is an excellent choice for industrial power tools and a must-have in any repair shop..
