During the use of Polyether L-42, common problems usually focus on several aspects: Defoaming\/foam suppression effect not meeting expectations (possibly due to insufficient dosage or improper dosing method), Cloudy or delamination of the formulation (may require adjustment of compatibility with other additives in the system), Product thickening or cloudiness at low temperatures (due to the cloud point characteristics of Polyether L-42, a normal physical phenomenon, transparency can be restored by appropriate heating), Residual water marks after cleaning (it is recommended to adjust the dosage of drying agents or optimize with other additives).
Polyether L-42 is a nonionic polyoxypropylene polyoxyethylene block copolymer ether, with stable chemical properties and good tolerance in acid, alkali, and high-hardness water. If abnormalities occur, first check whether the product is stored in the recommended temperature range (5°C to 35°C), whether the container is well-sealed, not moisture-affected, or contaminated with impurities.
