Because Fluorocarbon solvent products are expensive, we recommend that you try other surfactants first unless you have tried other types of products and still can't solve the problem, or when the primary goal is to develop products with special properties;
Please refer to the relevant product safety technical data (MSDS) before using Fluorocarbon solvent products. Although there is no evidence that Fluorocarbon solvent itself has toxic effects on human body, it is not recommended to apply it to any food, medical or other related products. industry;
All Fluorocarbon solvent products will increase in viscosity when the temperature drops, and some products will precipitate or even solidify into wax, but all the above phenomena will not have any adverse effect on the application performance of the product;
The product should be fully stirred before use to make it evenly mixed, and if necessary, it can be slightly heated (40 ~ 60 ℃). For some products with isopropanol as solvent (such as leel), it is not recommended to heat with an open flame because of its low flash point;
It is recommended to start adding 0.1% in water-based formulations and 0.25% in solvent-based formulations, and then adjust the concentration up and down to obtain the best application concentration suitable for the desired effect of the specific formulation;
For products with 100% active substances (such as leel), if necessary, the basic solvent of the system can be used to prepare 25~30% base liquid before use, so as to facilitate the use and accurately control the addition amount;
In principle, Fluorocarbon solvent products can be added at various stages of product processing according to the requirements of each specific application. Generally speaking, add as much as you can later, and the usage is basically in the way of adding while stirring;
The properties of Fluorocarbon solvent products such as reducing the surface tension of the system, especially the foaming properties, will change greatly with the change of PH value, so these factors should be considered when selecting products;
All suggestions on the application direction, dosage and usage of Fluorocarbon solvent products are guidance opinions based on theory and practical experience, and do not mean that the above requirements must be followed in practical applications. Each application formula has its own particularity, and how to apply Fluorocarbon solvent products is ultimately determined by specific experiments.
