Various aluminum alloy environment-friendly paint strippers ACHM01, ACHM04, AHLR03, AHLR03-D, AHLR05, PIC06, PIC07, etc. were soaked at 100~140°C.
According to the test results, AHLR03-D has the best effect.
The picture on the left shows 5 layers of hardened ink with AHLR03-D to remove the wheel arc.
However, AHLR03-D uses a C3~9 short carbon chain surfactant, which has a strong penetrating power, causing the hardened ink to decompose and make the agent turbid. After filtering with a 0.5μ filter, some powder still penetrates the filter and cannot be effectively filtered out. Tree fingers remaining in the agent may lead to a faster decline in the service life of the agent.
In addition, surfactants with short carbon chains have a low boiling point and tend to generate steam when heated, requiring large amounts of air to be pumped during use; at the same time, the loss of agents due to evaporation is also high. -
Using AHLR03-D as BASE, increase the carbon chain number of the surfactant to C6~12, C8~12, C6~18, C12~18, C14~20, and develop 5 aluminum alloy neutral water-based paint strippers at 140 Soak and strip paint at ~150℃. The potion No. 3 has the best effect. And after the 5 layers of hardened ink are peeled off, the agent is still transparent; the hardened resin is peeled off in one piece, and the resin has no dissociation phenomenon.

Reconstitute the medicament number 3 and repeat the test. It was found that the medicament was slightly turbid after continuous cleaning until the third branch, but there was no powder formed after the dissociation of the resin in the medicament. Peeling hard coating can be filtered out with a simple stainless steel strainer. The agent number 3 was named AHLR03-H.
