S0981 - Tinius Olsen - ASTM C736-00 Adhesion Test For Latex Sealants

Used on some of our smaller systems, the S0981 Tinius Olsen ASTM C736-00 Adhesion Test For Latex Sealants, quite a recent one, this grip design is used to test the strength of sealants and adhesives used in the production of windows.

It's quite a complex process to prepare the samples, using a c shaped 'mold' the sealant is injected between a glass and aluminium plate. These are held together using (good ol') G-clamps. It is then allowed to cure for a specific time... as it's nice to prepare a few of these samples to test, we provided a few kits (C section, and the aluminium and glass plates).

It was odd, as you had to remember that the test specimen was a liquid that needed to cure, in a mold. I was something that I had to keep reminding myself.

This test allows you to find the Adhesion strength of the Sealant between the desired structural material types. In this case glass and aluminium.
