Microbond® Washers

Microbond washers are dry to the touch adhesives, bonded to a mesh substrate and cut into various sizes. The adhesive in each washer is activated when crushed or sheared under the pressure of the fastener during installation. Microbond washers lock and seal under the head of the fastener, and provide a wide range of benefits when compared to metal lock washers, or even neoprene.

Description

First adhesive washer of its kind! Super light weight and dry to the touch!

Microbond Dri-Adhesive Washers are made from a fiberous material which holds ND Industries’ powerful Microspheres adhesive technology.

Microspheres, a material formed though a process known as microencapsulation, consists of tiny spheres or microcaps containing either an activator or adhesive. Although mixed together, the shell of each sphere keeps both parts separated allowing the material to stay dry and inactive until during assembly the force of engagement breaks open the microcaps causing activation.
