We have discussed the fact that all adhesives go through three stages of bonding until strength has reached its peak. Last week we started with the first stage, hydroxyl bonding. This week we want to explain and discuss the second stage, mechanical bonding.
Most people think of mechanical bonding as physical attachment, usually with nuts and bolts. To some extent, there are similarities. However, the definition of mechanical bonding is “the use or creation of more bonding surfaces.”
