Resorcinol glue, also known as resorcinol-formaldehyde, is an adhesive combination of resin and hardener that withstands long-term water immersion and has high resistance to ultraviolet light. [1] [2] The adhesive, introduced in 1943, has been popular in aircraft and boat construction. [2]
l-DOPA is a key compound in the formation of marine adhesive proteins, such as those found in mussels. [17] [18] It is believed to be responsible for the water-resistance and rapid curing abilities of these proteins. l-DOPA may also be used to prevent surfaces from fouling by bonding antifouling polymers to a susceptible substrate. [19]
The result was Aerolite, a urea-formaldehyde adhesive which unlike conventional glues of the time, resisted water and micro-organisms. Further research showed that gap-bridging hardeners incorporating formic acid enabled Aerolite to be used as an assembly adhesive. Aerolite was the first adhesive of its type to be invented and manufactured in ...
Marine invertebrates commonly employ protein-based glues for irreversible attachment. Some mussels achieve 800 000 N/m 2 on polar surfaces and 30 000 N/m 2 on non-polar surfaces [ citation needed ] these numbers are dependent on the environment, mussels in high predation environments have an increased attachment to substrates.
“Everybody has demons, but there are some wild kind of demons when you come back from combat,” said a Navy corpsman (the Navy’s name for its medics) who served a tour each in Iraq and Afghanistan and asked not to be identified by name. He was once unable to save a Marine with a terrible head wound, and afterwards felt other Marines blamed ...
It is suitable for marine, industrial, and decorative coatings. 2-Methylpentamethylenediamine can also be used as a chain extender for polyurethane applications, and in particular with PUDs. [3] [4] Its derivatives like aspartic esters, secondary amines, aldimines and ketoimines serve as curatives in polyurea systems.
