What You Should Know About Hot Melt Adhesive
In order to make epoxy work, you must combing resin and a hardening agent to make the bond as strong as necessary. With the help of hot melt adhesive, you can bond two different materials together easily while it seems a bit difficult for most adhesives recently. Most of the time, when you are making an epoxy adhesive, you do not mix the two parts together until you are ready to use them. Many are also thermo-activated, which means they also need heat in order to form the bonds.
Hot melt adhesive are considered to be the most powerful kind of adhesive. In many cases that's true. However, before using hot melt adhesive it's important to understand what they are and how they work. Here are the basics you need to know
• "Epoxy" is not a single catch-all term. Being different in strength, curing time and physical properties generates many different epoxies. That means some epoxies are meant to bond to certain types of surfaces such as plastic, fiberglass, ceramic, metal, etc. and other may not work as well on the same type of surface.
It also means that it's important to read the instructions and indications on any given epoxy you may be using.
• There are two-part and one-part epoxies. Since hot melt adhesive literally have to undergo a chemical reaction to cure and bond, the most common type of epoxy involves two components. Typically both have a paste- or glue-like consistency. They must be mixed together in the proper quantity and as they mix they begin to cure. Some of them are available as a one component type, which can simply be applied right out of the tube or container. While one components may seem more convenient, they also require high temperatures to cure and thus are less common in most applications. Two component types can bond at room temperature.
• Once you mix or apply an epoxy it is immediately undergoing a chemical reaction. It's important to plan out your work before you open or mix the epoxy adhesive. Once it is mixed you have limited time to apply it and put everything in place before the reaction is complete and the epoxy cures, hardens and binds. Hardened epoxy is very difficult to remove and often must be sanded away. Epoxy curing times can vary from a few minutes to an hour, so it's important to use it promptly.
High quality hot melt adhesive
It is a brilliant choice for many home projects as well as for a variety of professional tasks to use this kind of adhesive thanks to many types in the market. There are hot melt adhesive that take only one minute to set while others take as long as 12 hours to 24 hours to completely cure. Moreover these adhesives can be colored or transparent and have a gel-like consistency. In projects where two components are to be joined and high-strength bonding is needed, an epoxy adhesive usually accomplishes the job well. Compared to other types of adhesives in the market, epoxy is heat resistant and chemical-proof. A marine epoxy is a specialized type of epoxy that provides excellent adhesion for materials constantly immersed in water such as boats and kayaks, or those exposed to heat and moisture, which is usually the case with many outdoor applications.
The Master Mend Epoxy from Loctite is a 2-part epoxy adhesive that is perfect even for complex assembling, bonding, and sealing. It can work as filler for gap bonding or surface repairs and comes highly recommended even for fiberglass, stone, and concrete, which makes it an ideal all-around adhesive choice for a wide range of home and professional projects.
