Adhesives
As you probably know there are a lot of types of adhesives available on the market. More and more domains use various adhesives. To understand better the adhesive classification, you need to know that this can be done regarding their applications or by their chemical type. These adhesives that use chemical reactions are also the strongest adhesives. The others just use physical changes.
The first type of adhesives is the anaerobic adhesives. They are mainly based on synthetic resins, and are commonly used to secure and to seal close fitting parts. This is very good for metal. The cyanoacrylate adhesives are based on a moisture reaction that will lead to a strong bond. They are suitable for plastics and rubbers, and their main advantage is that they solidify in seconds. Another type is represented by the epoxies. The epoxy mixed with a hardener allows them to be very versatile and to be suitable for most of the materials. They produce very strong bonds and are available in one and two parts of in film form.
Toughened acrylics also offer strong bonds. They need no mixing, and they fit most o the materials. A good adhesive is the polyurethane. This adhesive offers an extremely strong bond that will resist to very low temperatures. Glass fibers, plastics are easy to bond for this type of adhesives. A very common adhesive is the silicone. Silicones are not so strong but are very flexible. They can be used for bath or shower sealants, and have a great durability.
You can also find on the market special adhesives that are designed to fit any kind of rubber. In case you find these adhesives unfit, you can always use polyamides or phenolics. These adhesives are great for bonding metals and have superior qualities. Also, pressure-sensitive adhesives are of great use. Tapes and labels usually use this kind of adhesive. Paper or wood can be at anytime bonded with polyvinyl acetate, also known as PVA.
As you can see, you can find an adhesive to bond any materials. You can always choose the right one from those three major adhesive types: thermosetting adhesives, thermoplastic adhesives and rubber-resin adhesives. Depending on their bond strength and durability, flexibility, versatility or price, you can choose the one to fit the type of job you are about to do. If you have any problems in choosing the right one, you can always ask for a professional opinion.
