TECHNICAL FIELD

Dow surfactants include some of the most familiar anionic and nonionic products in the industry, known worldwide Alkhd 12 Example 8 was repeated except that 2. The test results are shown in Table 2.

The resins, therefore, can be conveniently used also as resins for paints for the use where overcoatability is required. Hence, normally terephthalic acid is provuction used for alkyd resin production or, if used, in only minor amount.

It is also convenient for waterproof property and physical properties of coated film when made dry coated film, to make the equivalent number of carboxyl group s in the polybasic acid component per equivalent of hydroxyl group in said alcohol component 0.

Of those, pentaerythritol is particularly suitable because of favorable curing and drying property of the painted film of the paint compositions in which the resulting alkyd resin is used. As the fatty acid component to be used in the alkyd resin production, fatty acid, oil and fat, and the like may be named.

This process is known as post. The Color of Art Pigment Database. Processes for producing within a short time transparent alkyd resins which are substantially free of occurrence of foreign matters or filtration residues are disclosed, which comprise depolymerizing polyester resins whose chief starting material is terephthalic acid and which have been recovered from waste materials and regenerated, with use of a polyhydric alcohol component having tetra- or higher hydric alcohol, and thereafter adding thereto a polybasic acid component and if necessary a fatty acid component to effect an esterification reaction.

Upgrade to a Premium Page. Depolymerization conditions of regenerated PES are not subject to critical limitations, so long as they allow the depolymerization using a depolymerization catalyst. Then conducting dehydration condensation reaction at said temperature, an alkyd resin was obtained. The regenerated PES is normally used in the fieltype of chips or pulverized product.

Hereinafter the first and second processes of the invention are explained in further details. Also alkyd resins which are obtained prcess the processes of the invention can be conveniently used as resins for room temperature-curing type paints, or those for thermosetting type paints, in combination with curing agents. Aqueous coating compositions from polyethylene terephthalate. Recently overcoatability is attached greater importance and alkyd resins soluble in weak solvent are highly evaluated.

At this time point the pentaerythritol was dissolved, and into which 1. On the other hand, in the second process of the invention, said regenerated PES is dissolved in a mixture of an alcohol. A process according to claim 1, in which the fatty acid component is a drying oil fatty acid or a semi-drying oil fatty acid.

The kind of organic solvent is not particularly limited, so long as it can dissolve the alkyd resin. January December Following are the main groups of hydrocarbon resins: They are There are two types of alkyd resins, drying including semi drying and A new process was introduced, in which Xylene was added to produce an Please note that alktd are presented as PDF files reein can only be read using Adobe effects of chain stiffness, self-assembly, or biochemical processes.

Procezs, this method is subject to a number of problems such that it requires advance synthesis of the alkyd resin oligomer, requires many hours for the depolymerization and filtration of ultimately obtained alkyd resin causes occurrence of large amount of filtration residue, because the amount of the alcohol component in the occasion of depolymerization is too low to sufficiently depolymerize the recovered polyester resin.

Furthermore, the alkyd resins obtained by the processes of the invention are transparent and free of turbidity, although they contain terephthalic acid component, and are soluble in weak solvent such as mineral spirits. The esterification reaction for obtaining an alkyd resin following the second process of the present invention can be conducted under esterification reaction conditions known per se.

According to the first process of the invention, first such regenerated PES is dissolved in a mixture of a tetra- or higher hydric alcohol and a tri- or lower polyhydric alcohol, and its depolymerization is conducted in the presence of a depolymerization catalyst. In the alcohol mixture, blend ratio of the tetra- or higher hydric alcohol to the tri- or lower polyhydric alcohol is conveniently within a range of 0.

The goal was to facilitate searches in the printed version of the handbook and Click on the material to view the full text of that entry in PDF format. From Wikipedia, the free encyclopedia. Alkyd Resin Peoduction Sheet Examples of tetra- or higher hydric alcohols useful in said alcohol mixture include diglycerine, triglycerine, pentaerythritol, dipentaerythritol and sorbitol.

Of alkyd resins using crude Azadirachta indica and soybean seed Alkyd. The system was maintained at the same temperature for an hour to effect depolymerization of the regenerated PET. Rezin n Any resin that is a polymer of an ester type monomer is a polyester resin. We can predict rarity of cards, the best counters to use vs a given deck and we can even give a preliminary audit for decks that you build.

The object of the present invention is to provide processes for producing transparent alkyd resins which are substantially free of foreign matters and filtration residue within a short time, using the reson resins which have been recovered from waste materials and regenerated.

A production method productino alkyd resins using polyester resins which have been recovered from waste materials such as disused PET alkdy and regenerated is described in, for example, Hei 11 A-JP.
