Adhesive mixing tips

Epoxy AB glue consists of two parts: epoxy resin and curing agent. After these two parts are mixed, they change from liquid to solid after a certain period. This stage is called curing. The curing time also varies according to the ratio. Some can be cured in a few minutes, and some can be cured in a few hours. However, it usually takes 24 hours to fully cure. The stages of the curing process The curing process is divided into three stages: Liquid-Gel-Solid Liquid phase The handling time is a part of the curing time. When the two components of the AB glue are mixed and the epoxy chemical reaction begins, the mixture is still in a liquid state and can be glued and potted. Gel stage When the epoxy mixture begins to gel or heat, it enters the initial curing stage, at which time the AB glue gradually changes from a sticky gel state to a hard rubber state. Solid stage When the epoxy resin and hardener are fully reacted, the mixture cures to a solid state and continues to cure for the next 24...

Two-component adhesives consist of resin and hardener. The two components are mixed and cured in a particular proportion to obtain the effect of bonding. These two components can be cured at room temperature. Therefore, it is necessary to control the mixing ratio of the two components to achieve the best mixing time , and p revent curing too fast or too slowly. There are four types of common resins: 1. Epoxy resin Two-component epoxy adhesives  bond metals, plastics, fiber-reinforced plastics (FRP), glass, and some rubbers. 2. Methyl methacrylate Classic applications are the automotive industry and rail vehicle manufacturing. 3. Silicone adhesive Two-component siloxanes are commonly used in production line assembly, for example in the electronics and electrical industry as well as in the production of household appliances, in the automotive industry, and in window manufacturing. 4. Polyurethane For bonding materials with different flexibilities or different coefficients of thermal ...

The mixing nozzle is used to mix two-component adhesive. It is composed of a series of upper, lower, left, and right rotating blades arranged in the casing in sequence and perpendicular to each other. According to whether the mixing element can be moved, the mixing nozzle is divided into static mixing nozzle and dynamic mixing nozzle. Static mixing nozzle   Static mixing nozzle does not need to be driven by an external force, it only uses the fluid itself to pass through the mixer to perform continuous cutting and overlapping to convert more than two materials into a uniform mixed solution Dynamic mixing nozzle     The spiral blades in the dynamic mixing tube can rotate quickly and stop instantly. This unique mixing tube is suitable for mixing liquids with different proportions, liquids containing foam and high viscosity (such as ethane, rubber, etc.) and various two-component adhesives and fillers (such as epoxy resin), silicone epoxy resin, PU, UV glue, etc.). Applicat...

How to Glue Wood with Two-Part Epoxy ？ Advantages of two-part   epoxy Two-part epoxy resins   are known for their high-performance strength and durability. The excellent bonding properties of epoxy resin and the combination of curing agents make it widely used in the wood processing industry, mainly as a sealant or filler, its waterproof seal makes it easy to clean. After the glue is fully cured, it can  be polished  or drilled, which is  ideal for wooden tables or furniture. Application tip s of epoxy on wood First, clean and dry the surface to be bonded. For wooden boards, it is usually necessary to use sandblasting, electric grinding wheels, wire brushes, or coarse sandpaper to polish, and then clean with detergents to avoid oil stains and other stains on the wood surface and improve adhesion. Secondly, it is necessary to match the   two-component epoxy   resin. In order to make the mixing of AB epoxy resin more uniform and improve the mixing eff...

How to choose the right static mixer for your project ? Introduction If you're working on a project that involves mixing two liquids  together, you'll need to choose the right static mixer for the job. But with so many different types and sizes of static mixers on the market, how do you know which one is right for your project? In this blog post, we'll explain why you need a static mixer and how to choose the right one for your needs. Why do you need a static mixer ? What is a static mixer? A static mixer is u sed t o mix two or more liquids  together. The static mixer consists of a series of elements, that work together to achieve the desired result. The benefits of using a static mixer There are many benefits to using a static mixer, including: -They require no moving parts, which means there are no parts that can break or wear out over time. -Static mixers are often less expensive than their counterparts that utilize moving parts. -They are simple to install and operate...
