Super glue/epoxy for work holding - practicalmachinist

Oct 04, 2016 · When using superglue it's good if the substrate is not really smooth. The glue needs someplace to go as it levels out. I use plexi as a substrate for a lot of cnc work, I surface it before glueing in the machine with a heavy feedrate to induce a bit of poor surface. Then hit it with a really coarse file, actually a checkering file.

Epoxies | Epoxy Adhesives Are Ideal for Metals, Plastics ...

Epoxies are ideal for metals, plastics, rubber, wood, glass and ceramics, and epoxy adhesives will fill the gaps between poorly fitting parts. They can also be sanded, cut, and painted after curing. Many applications benefit from an epoxy primer because epoxy primers are thin and provide for better adhesion by penetrating into a substrate to create a better bond.

Enzyme Biochemistry - What They Are and How They Work

An enzyme is defined as a macromolecule that catalyzes a biochemical reaction. In this type of chemical reaction, the starting molecules are called substrates. The enzyme interacts with a substrate, converting it into a new product. Most enzymes are named by combining the name of the substrate with the -ase suffix (e.g., protease, urease).
