Shenzhen glue manufacturer AB glue sticks aluminum alloy, brand Ergo glue strength replaces welding 123
glue manufacturersWhat AB adhesive is stronger for aluminum alloy? After more than ten years of domestic market verification, German imported AB adhesive brand DM adhesive strength can exceed welding. Renowned companies such as Foxconn and Xiaomi have cooperated on projects; The AB adhesives used for bonding aluminum alloys with DM adhesive mainly include epoxy resin AB adhesive and modified acrylic AB adhesive. Among these AB adhesives for bonding aluminum alloys, the one with outstanding performance is DM metal specific AB adhesive; Recommended reading: AB glue with strong metal adhesion
Application scope of aluminum alloy DM adhesive:
1. Self adhesive aluminum alloy
2. It can also be used for bonding aluminum alloy with metal materials such as iron, steel, stainless steel, lead, etc;
3. It takes 5-8 minutes to locate at room temperature (25 ℃), 3-5 minutes to locate during high temperatures in summer, and two to three hours to reach the strength of use;
Advantages of AB adhesive bonding aluminum alloy:
1. After curing, it is hard but not brittle, and can withstand high temperatures of around 120 degrees Celsius; 2. Has excellent impact and vibration resistance, low shrinkage, and good insulation and sealing effect; 3. The cured material has excellent properties such as acid and alkali resistance, salt spray resistance, solvent resistance, aging resistance, waterproofing, and oil resistance;
Application method of AB adhesive aluminum alloy for DM metal:
1. One method is to mix metal specific AB adhesive evenly in a weight ratio of 1:1, then apply it to one surface of the aluminum alloy part to be bonded, and then bond it. The disadvantage of this method is that there is a strong odor during the mixing process, and the operation time is relatively short after removing the mixing time, which can easily lead to waste; 2. Another method is to use A+B tubular packaging combined with specialized tools to directly apply the adhesive solution to the surface of the aluminum alloy to be bonded, without the need for mixing, which can effectively improve operation time and reduce odor.
To ensure the bonding effect of AB adhesive on aluminum alloy, attention should be paid to:
1. Before using DM metal special AB adhesive, the rust, oil stains, dust, rust proof oil, etc. on the surface of the aluminum alloy coating should be cleaned. If the surface of the aluminum alloy is too smooth, it needs to be roughened and cleaned before applying the adhesive;
2. The one-time mixing of glue should not exceed 100 grams. The more mixed, the faster the reaction of metal specific AB glue and the shorter the operation time;
3. Strictly mix the adhesive according to a weight ratio of 1:1, and mix it evenly. The colors of A and B agents of DM metal special AB adhesive are green and red. After mixing evenly, the adhesive liquid is semi transparent, and the red and green colors cannot be seen; The glue doesn’t need to be too thick, but it should be evenly applied.
4. After using DM metal AB adhesive to bond the aluminum alloy parts, do not move them violently in a short period of time to avoid misalignment between the two objects. If testing performance is required, it should be done after 24 hours.
