Waterproof Adhesive
Among the various types of adhesives we can find the waterproof adhesives. What are these adhesives? As the name says it, these are adhesives resistant to water. Until now, people had problems because of the water. This need lead to the invention of these adhesives. Now, we use them everywhere in our homes. This adhesive can create a resistant bond between numerous porous and less porous materials. This adhesive is mainly designed for severe service applications. Made of a powdered catalyst and a liquid resin, the waterproof adhesive is impervious to salt or water. Also, it is immune to oil, grease and solvents or to high temperatures. These things made the waterproof adhesive very popular.
Believe it or not, these adhesives find their roots to ocean creatures. There are numerous sea creatures that have been clinging under water in a natural way for millennia. We are talking about the mollusks. The feet of these creatures produce some substances that have adhesive-like properties. These substances are sometimes better that most of the glues available on the market today. Unfortunately it would take thousands of mollusks to produce just a small quantity of waterproof adhesive. The costs would be also huge.
The domains that use waterproof adhesives are various. The Navy and the marine industry are probably the best consumers. Because the salt that is contained in the sea water can break down most of the adhesives, they need very strong waterproof adhesives. They use it to build or to repair their ships. The building industry is an important consumer too. They require strong cementing adhesives for manufacturing different materials that usually deteriorate in contact with water. Also, the dental industry uses a certain kind of waterproof adhesive. They need it for dentures and in other domains that require suture prosthetic technologies. Scientists now try to find ways to produce adhesives that look like the ones that the mollusks use. If they will succeed, we will have a better and natural waterproof adhesive, which will remain intact in contact with water and any other fluids.
If you ever want to use a waterproof adhesive, you need to know that you need special cloths, facial and hand protection. They can sometimes be toxic, and it is better to use gloves and facial protection. The adhesive must be prepared at home or at your work place. You will have some instructions, that will help you mix it and to apply it right.
