Description

529,767 Water-borne alkyds discussed above provide drying properties comparable to conventional and traditional solvent-borne alkyds. However, they are not used to a greater extent as the film properties tend to be worse than in solvent-based alkyds, especially in air-drying systems. Water-borne alkyds typically have, as shown above, high acid numbers and are neutralized before water dilution, while conventional alkyds have low acid numbers which do not provide water dilutability if and when neutralized. Film formation occurs by the release of äm-rich substances followed by crosslinking by autoxidative reactions at room temperature or elevated temperature. Solvents are used such as coalescence, ie to promote film formation and improve film quality. Relative humidity can have a significant effect on the drying process and the glue quality. Water-repellent formulations with good properties under dry conditions can be substandardly high humidity. The water outlet is much lower at high humidity, but the solvent outlet continues. this results in solvent deficiency during the critical phase of film formation and consequently poor film development. The slow release of amine or ammonia, used to neutralize the high acid number, leads to temporary high water sensitivity. Even in the completely dry film, the presence of unreacted carboxyl groups leads to films with relatively poor water resistance, which limits their usefulness. Water-borne and solvent-based alkyds are described and discussed in detail in "Surface Coating Technology" vol. VI "Waterborne and Solvent Based Alkyds and Their End User Applications", by N. Tuck, John Wiley and Sons © 2000 SITA Technology Ltd.

Latex and water-soluble polymers dry by different mechanisms for alkyd resins. A latex is composed of polymer particles dispersed in water and film formation occurs when the particles fuse together to form a continuous film. The particles must have a glass transition temperature (Tg) which is low enough for them to surface and adhere to each other at the application temperature. Coalescences act as temporary plasticizers during the film formation process, which promotes Tg lowering and emission, and then resigns after film formation has occurred. The most common coalescences are slowly leaving glycol ether residues.

Glycols such as ethylene glycol or propylene glycol are often added for storage stability and as antifreeze agents.

The nanoscopic polymer of the present invention makes it possible to transfer conventional resin systems, such as polyesters, oil-modified polyesters, regardless of oil length, polyurethanes, vinyl polymers and the like to waterborne systems for applications such as coatings. The nanoscopic polymers can also be used as such for the production of, for example, waterborne systems of said types and for said applications.

The nanoscopic polymer of the present invention is composed of at least one hydrophobic moiety derived from a saturated or unsaturated monocarboxylic acid, which is esterified with a polyhydroxy compound, and a cationic, anionic or nonionic hydroxy moiety attached to said hydrophobic moiety with ester or urethane bonds.

The nanoscopic polymerizer of the present invention eliminates the presence of commonly used emulsifiers. The advantage of the present invention is that the nanoscopic polyurea participates in the annealing process, either physically, as a plasticizer for annealing polymers, when the hydrophobic moiety is derived from a saturated oligoester or polyester and / or chemically by autoxidative drying then said hydrophobic moiety. or polyester.
