Definitions
- uretdione group-containing polyurethane compositions which are curable at low temperature and contain (partially crystalline resins
- the invention relates to uretdione-group-containing polyurethane compositions which are curable at low temperature and which contain (semi-) crystalline resins, in particular for polyurethane powder coating and inorganic compositions which are curable at low temperature, a process for their preparation and their use.
- Solid at room temperature, externally or internally blocked polyisocyanates are valuable crosslinkers for thermally crosslinkable polyurethane (PUR) -Pulverlack- and adhesive compositions.
- PUR thermally crosslinkable polyurethane
- DE-OS 27 35 497 PU powder coatings with excellent weathering and heat stability For example, DE-OS 27 35 497 PU powder coatings with excellent weathering and heat stability.
- the crosslinkers consist of ⁇ -caprolactam blocked isocyanurate-containing isophorone diisocyanate.
- DE-OS 30 30539 and DE-OS 30 30 572 describe processes for the preparation of uretdione group-containing polyaddition compounds whose terminal isocyanate groups are blocked irreversibly with monoalcohols or monoamines. Disadvantages are, in particular, the chain-breaking constituents of the crosslinkers, which lead to low network densities of the PU powder coating and thus to moderate solvent resistance.
- Hardening reaction does not emit volatile compounds.
- the firing temperatures are at a high level of at least 180 ° C.
- amidines as catalysts in PUR Pickverlackzusammen aciden is described in EP 803 524. Although these catalysts lead to a lowering of the curing temperature, but show a considerable yellowing, which is generally undesirable in the coating area. The reason for this yellowing is probably the reactive nitrogen atoms in the amidines. These can react with atmospheric oxygen to N-oxides, which are responsible for the discoloration.
- EP 803 524 also mentions other catalysts which have hitherto been used for this purpose, but without showing any particular effect on the curing temperature. These include known from polyurethane chemistry organometallic catalysts such. As dibutyltin dilaurate (DBTL), or tertiary amines, such as. For example, 1,4-diazabicyclo [2.2.2] octane (DABCO).
- Such catalysts are in fact capable of lowering the curing temperature of uretdione group-containing polyurethane powder coating compositions, but show as reaction products mainly allophanates (Gedan-Smolka M., Lehmann F., Lehmann D. New catalysts for the low-temperature curing of uretdione Powder Coatings "International Waterborne, High solids and Powder Coatings Symposium, New Orleans, 21-23.02.2001).
- Certain catalysts accelerate the cleavage of uretdione groups so strongly that, when using uretdione group-containing curing agents, the curing temperature of powder coating or adhesive compositions can be considerably lowered. Due to the low curing temperature, a high melt viscosity is present. This leads to development problems and surface defects of the powder coating films. The high glass transition point of conventional PUR powder coating raw materials can lead to brittle coatings in the case of insufficient crosslinking.
- uretdione-containing paint or adhesive compositions can be cured under normal conditions (DBTL catalysis) only from 180 ° C.
- DBTL catalysis normal conditions
- inventive low-temperature curing polyure compositions can be saved at 100 to 160 ° C curing not only energy and curing time, but it can also coat many temperature-sensitive substrates or bonding, the at 180 ° C unwanted Vergübungs-, decomposition and / or show signs of embrittlement.
- certain aluminum substrates are also predestined. In the latter case, excessive exposure to terrorism sometimes results in an undesirable change in the crystal structure.
- At least one hardener containing uretdione groups based on aromatic aliphatic, (cyclo) aliphatic and / or cycloaliphatic polyisocyanates and hydroxyl-containing compounds having a free NCO content of less than 5% by weight and a uretdione content of from 1 to 18% by weight; and

- the invention also adhesive compositions and the use of the polyurethane compositions according to the invention for the production of bonds of metal, plastic, glass, wood, or leather substrates or other heat-resistant substrates.
- the invention also relates to metal-care compositions, in particular for automobile bodies, motorcycles and bicycles, building parts and household appliances, wood-care compositions, glass-coating compositions, leather-coating compositions and plastic-coating compositions.
- Polyisocyanates containing uretdione groups are well known and are described, for example, in US Pat. Nos. 4,474,054, 4,912,210, 4,929,724 and EP 0417,603.
- soluble dimerization catalysts such as.
- the reaction - optionally carried out in solvents, but preferably in the absence of solvents - is stopped when a desired conversion is achieved by addition of catalyst poisons. Excess monomeric isocyanate is subsequently separated by short path evaporation. If the catalyst is volatile enough, the reaction mixture can be freed from the catalyst in the course of Monomerenäbtrennung. The addition of catalyst poisons can be dispensed with in this case.

- the catalysts are contained in an amount of 0.001 to 5 wt .-%, preferably 0.01 to 3 wt .-%, based on the total formulation, in the polyurethane composition.
- hydroxyl-containing (partially) crystalline polymers C preference is given to using polyesters, polyethers, polyacrylates, polyurethanes, polyethers and / or polycarbonates having an OH number of from 10 to 500 (in mg KOH / gram). Particularly preferred are hydroxyl-containing polyesters having an OH number of 20 to 150, an average molecular weight of 500 to 6000 g / mol. Of course, mixtures of such polymers can be used.
- the proportion by weight of this (partially) crystalline component C) in the overall formulation can be between 1% and 95%, preferably from 2 to 50%.
- crystalline hydroxyl-containing polyesters are prepared by polycondensation. This is an acid component consisting of 80-100 mole percent of a saturated linear aliphatic or cycloaliphatic dicarboxylic acid having 4 to 14 carbon atoms and 0 to 20 mole percent of another aliphatic or cycloaliphatic or aromatic di- or polycarboxylic acid, having an alcohol component consisting of 80 to 100 mole percent a linear aliphatic diol having 2 to 15 carbon atoms and 0 to 20% of another aliphatic or cycloaliphatic di- or polyol having 2 to 15 carbon atoms reacted.
