What glue does Shenzhen glue manufacturer use for PVC bonding aluminum alloy? 123
Polymers formed by free radical polymerization reaction mechanism under the action of initiators such as peroxides and azo compounds, or under light and heating conditions. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. Aluminum alloy is a widely used non-ferrous metal structural material in fields such as aviation, aerospace, automotive, machinery manufacturing, shipbuilding, and chemical industry. With the rapid development of industrial economy, the demand for aluminum alloy welded structural components continues to increase, so the research on the welding performance of aluminum alloys has become increasingly in-depth.
To bond PVC and aluminum alloy, it is recommended to use AB adhesive DM1665. The customer’s product is a PVC strip and two aluminum alloy sheets, used for tile joints, laid on the ground, mainly used in large shopping malls, warehouses, production bases, underground parking lots, shopping centers, and residential areas. PVC strips and aluminum alloys need to be seamlessly bonded without damaging the surface. The actual total length of each product is 2.5 meters.

The adhesive viscosity of acrylic structural adhesive 1665 is 100000 mPas, with a construction time of 8-10 minutes and a positioning time of 15-20 minutes. After mixing, it appears light blue with a mixing ratio of 1:1. Complete curing takes 24 hours, with a temperature range of -55 ℃ to+120 ℃, and can fill gaps of 10mm. When using 1665AB adhesive for bonding, it is important to use a glue gun to squeeze out the adhesive until the color turns light blue, which indicates thorough mixing. The surface of PVC and aluminum alloy to be bonded must be clean and free of grease. After applying AB glue, appropriate pressure can be applied. Complete curing at room temperature takes 24 hours, while curing can be accelerated by heating at lower temperatures.
