How to choose adhesiveBasic information of acrylic structural adhesive DM Acrylic structural adhesive is a two-component, fast curing adhesive system with 100% reactivity. Adhesives and accelerators are packaged separately and can be used separately. They are suitable for bonding structural components that require high tensile, shear strength, and peel strength; Require good impact resistance, pressure resistance, and seismic resistance, as well as durability under harsh environmental conditions such as extreme temperature conditions and thermal cycling; And excellent resistance to chemical corrosion.
According to the so-called non mixing process, it is possible to allow sufficient time for the parts to be joined to be wetted and adjusted. Curing only begins after the parts are joined together At the same time, it also provides acrylic glue (such as DM. 1850) with the same consistency as the glue (A/B system) as a promoter. These adhesive varieties, adhesives, and accelerators can be used separately. When dispensing, two drops are placed side by side or one drop is placed on top of the other. In any case, the usage method should ensure that the accelerator and adhesive can be mixed together when the two components are joined. Unlike other two-component adhesives such as epoxy adhesives, the mixing ratio of adhesive and promoter is not very important. The formula of these adhesives ensures that they can be used to bond substrates with different properties, such as metals, ceramics, glass, magnets, sintered metals, aluminum, hard plastics, etc.
Typical applications include bonding hinges on glass window doors or bonding mirrors on car windshields. The strong adhesion to magnets and metals also makes these adhesives suitable for bonding magnetic steel and tiles in the amplifier industry, DC motor components, and coil manufacturing. To achieve optimal performance, the joint surface must be clean and free of any contaminants such as dirt, oil stains, lubricants, and any previously applied products. A slight grinding treatment on the surface before joining can achieve the best results. We recommend using Ego9195 cleaner for surface cleaning of glass and plastic, and Ego.9190 cleaner for metal. If mechanical pretreatment such as grinding, sanding, sandblasting, etc. can be carried out, it will greatly optimize the adhesion surface. Adhesive should be applied on one surface, and a promoter (usually with lower viscosity) should be applied as a paint film on another surface.
Before application, never mix the two components. The accelerator remains in liquid state; No need to consider flash evaporation time. The parts should be assembled within 15 minutes. After the parts are assembled, the two components can be thoroughly mixed, and a high initial bonding strength (operable strength) can be achieved within seconds to minutes. Curing mechanism DM Acrylic structural adhesive is a two-component reactive adhesive. After the parts are joined, the active polymerization (curing) can immediately begin through direct contact between resin (adhesive) and accelerator (promoter). An increase in temperature (about+50C) will significantly accelerate the curing process. Do not move the parts again until the initial fixed time is reached.

These products have good resistance to water, grease solvents, oils, lubricants, inorganic acids and bases released by glass. Adhesive components can be used within a temperature range of -40 ° C to+120 ° C, and some products can withstand high temperatures above+150 ° C. Storage and shelf life DM Acrylic structural adhesive stores products in unopened containers in a cool and dry environment. The optimal storage temperature is+8C to+23C. Under the above storage conditions, the shelf life is 12 months from the date of shipment, as indicated by the expiration date on the packaging label. Protect the product from the effects of frost, heat, and direct sunlight. Related reading recommendation: “The difference between single component and two-component adhesives”
