Epoxies are two-part adhesives consisting of an epoxy resin and a hardener. After the components have been mixed, the material converts to a solid state. They are multipurpose. They can be used for laminating, coating, casting, gap filling and more.
Epoxies are mixed in ratios between 2:1 and 4:1 resin to hardener. The reaction between the liquid components is known as curing. After this process, they gain toughness, strong adhesive properties and chemical resistance. Curing time varies depending on type of resin and temperature applied. Many of them will cure at room temperature.
They have the advantage of a long working time. Liquid state persists between 15 and 100 minutes before solidification. This allows users to shape and form the epoxy as desired before curing.
• High adhesion strength
• Low shrinkage during cure
• Resistance to shattering, splintering and abrasion
• High heat resistance
• Resistance to chemicals, acid and corrosion
• Strong insulating properties
The applications for them are extensive. Epoxy-based materials can be produced with a broad range of properties. They can be applied to most materials, including wood, metal and glass.
Epoxy resin is a strong adhesive, often used in the construction of vehicles. It can also be used for arts and crafts projects and to repair fragile items. They are common in electronics, thanks to their excellent insulating properties. They are used for integrated circuits, transistors and PCBs.
Epoxy paint is commonly used for the coverage of floors. They are also ideal to coat white goods, preventing corrosion by rust.
