This adhesive is designed to function with indoor applications and is suited for application to many substrates, including plastics.
Secure, Repeated Closures
3Mâ„¢ Hook and Loop Fasteners offer great design flexibility, fast product assembly, smooth and clean exterior surfaces and excellent product performance in many applications. 3M Hook and Loop Fasteners consist of hooks and loops which engage to form a quick fastening attachment.
