What Is Fluorine-modified Leveling Agent
Fluorinated leveling agent is a type of leveling agent modified with fluorinated groups, designed to enhance the flow and leveling properties of coatings and other liquid materials. The inclusion of fluorinated groups in its molecular structure provides superior wettability and chemical resistance in various environments. Fluorinated groups have very low surface tension, helping to effectively lower the surface tension of the liquid and improve flow. Improves the evenness of coatings or inks during application, preventing issues such as runs and streaks. Aids in forming a smooth and uniform surface during curing, enhancing appearance.
Advantages of Fluorine-modified Leveling Agent
Surface Tension Reduction
Fluorine-modified acrylate leveling agents can lower the surface tension of the coating formulation. This reduction in surface tension helps the coating spread more evenly over the substrate, promoting improved wetting and leveling.
Enhanced Wetting
The presence of fluorine groups can enhance the wetting properties of the coating. Improved wetting ensures that the coating forms a more uniform and cohesive film on the substrate, reducing surface defects like pinholes, craters, and orange peel.
Prevention of Surface Defects
Fluorine-modified acrylate leveling agents are often used to minimize or eliminate surface defects in coatings, such as bubbles or uneven film thickness. This leads to a smoother and more aesthetically pleasing surface finish.
Improved Flow and Levelling
These agents help in the flow and leveling of the coating during application and drying processes. They promote the even spreading of the coating material, resulting in a more uniform film thickness and reduced drying marks.
Substrate Adhesion
Some fluorine-modified acrylate leveling agents can enhance the adhesion of the coating to the substrate. This is particularly important for coatings applied to challenging surfaces, such as low-energy substrates like plastics or metals.
Chemical and Weather Resistance
The incorporation of fluorine atoms can impart chemical and weather resistance to the coating. This makes the coated surface more durable and less susceptible to degradation from environmental factors.
High-performance coatings
Enhances the evenness and smoothness of coatings, reducing surface defects.
Automotive coatings
Improves the appearance and durability of coatings.
Industrial coatings
Boosts flow and surface quality of coatings.
Cleaners and protective coatings
Enhances surface smoothness and chemical resistance.
Fluorine modified polymer type levelling agent has excellent leveling and re coating properties; It can improve the wettability of substrate and prevent the shrinkage, pinhole and fish eye defects of coating film to obtain the best leveling effect. It is stable in nature and difficult to hydrolyze. It has excellent light resistance and aging resistance, and is not volatile. Therefore, in addition to improving the leveling of coating system, it also has plasticizing effect; Good compatibility with most coating systems.
The added amount depends on the coating system, and generally the total amount is 0.1-0.5%. Before use, please test the proper dosage and compatibility with coating system.
Keep in a cool and ventilated place. Keep the container tightly away from heat and fire. The storage environment is between 0 and 40 degrees centigrade.

Wherein said solvent is dimethylbenzene, N-BUTYL ACETATE, propylene glycol monomethyl ether or 1-Methoxy-2-propyl acetate; Fluorinated acrylate monomer is vinylformic acid trifluoro ethyl ester, trifluoroethyl methacrylate, vinylformic acid hexafluoro butyl ester, methacrylic acid hexafluoro butyl ester, dodecafluorhe-ptylacrylate or methacrylic acid ten difluoro heptyl esters; Acrylate monomer is methyl acrylate, ethyl propenoate, butyl acrylate or acrylic acid-2-ethyl ethyl ester; Initiator is Diisopropyl azodicarboxylate or benzoyl peroxide.
Preparation method: In the four-hole boiling flask that has reflux condensing tube, thermometer, agitator and dropping funnel, add 30～40% weight parts in the N-BUTYL ACETATE, and start agitator and stir; When temperature rises to 118 ℃, after the equal solvent N-BUTYL ACETATE refluxes in prolong, begin to drip by 30～40% weight parts in the N-BUTYL ACETATE, methacrylic acid ten difluoro heptyl esters, 70～90% weight parts in butyl acrylate, the Diisopropyl azodicarboxylate, finish dropping behind the 2h, maintain the temperature at 118 ℃ then and continue to stir 2h; The mixture of the Diisopropyl azodicarboxylate of the N-BUTYL ACETATE of benefit dropping surplus and surplus is 10 minutes again, maintains the temperature at 118 ℃ then and continues to stir 2h.Insulation transfers to 70 ± 2% with solid content after finishing, and takes out product.
Wherein said solvent is dimethylbenzene, N-BUTYL ACETATE, propylene glycol monomethyl ether or 1-Methoxy-2-propyl acetate; Fluorinated acrylate monomer is vinylformic acid trifluoro ethyl ester, trifluoroethyl methacrylate, vinylformic acid hexafluoro butyl ester, methacrylic acid hexafluoro butyl ester, dodecafluorhe-ptylacrylate or methacrylic acid ten difluoro heptyl esters; Acrylate monomer is methyl acrylate, ethyl propenoate, butyl acrylate or acrylic acid-2-ethyl ethyl ester; Initiator is Diisopropyl azodicarboxylate or benzoyl peroxide.
Above-mentioned substep usage ratio with a kind of component is with embodiment.All the other are with embodiment. Gained flow agent surface tension: 24-26 dyne, number-average molecular weight are 2000～4500, and weight-average molecular weight is 5000～12000, polymolecularity 2.0～2.8. Illustrate: solvent based coating fluorinated acrylate flow agent, the surface tension value of pure acrylic acid ester flow agent and acrylic varnish stoste: if in acrylic varnish, add fluorinated flow agent and pure acrylic acid ester flow agent 0.1%, 0.3%, 0.5%, 0.8%, the surface tension downtrending figure of acrylic varnish respectively.
More than explanation can well reduce the surface tension of acrylic varnish when the surface tension value of fluorinated flow agent during at 24.542 dyne.Again because the surface tension value of varnish has reduced, so this varnish has nonshrink preferably hole ability, ground wettability and levelling speed. Pure acrylic acid ester flow agent and fluorinated acrylate flow agent are added to respectively in the paint, require to make the lacquer plate in accordance with regulations, test following data with tangerine peel instrument and glossometer.
The controlled nature of fluorine-modified leveling agents is achieved by changing the molecular weight. Homopolymer compatibility is not as good as copolymer, such as homopolymer acrylic acid is usually poorly compatible with epoxy, polyester, polyurethane and other resins used in coatings, if they are mixed with physical methods will form a poor surface state of the non-light coating film, so acrylic homopolymer is not very suitable for leveling agents. The ideal levelling agent is a copolymer, which can be a terpolymer, or a modified copolymer, and only the copolymer can change the polymer's *ness and glass temperature through different monomers.
Usually the number average molecular weight of fluorine-modified leveling agents is controlled between 6000-20000, the molecular weight distribution is relatively narrow, the glass flower temperature is controlled below -20°C and the surface tension is below 25-26mN/m. This compatibility limited acrylic copolymer is considered a good levelling agent.
Acrylic levelling agents can be homopolymers or copolymers; linear structures or those with branched chains; random copolymers or block copolymers.
