Definitions
- the present invention relates to lightfast polyurethanes and their use.
- PUR Polyurethanes
- Moldings are therefore selected from aliphatic starting materials and, in the case of isocyanates, those compounds in which the NCO groups are not bonded directly to an aromatic group.
- WO 2004/000905 uses such aliphatic isocyanates for the preparation of lightfast polyurethanes. It also addresses the problem of high volatile organic compound (VOC) levels, with peak levels of 250 ppm, preferably ⁇ 100 ppm, being required by the automotive industry for automotive interior applications.
- VOC volatile organic compound
- the solution used in WO 2004/000905 are incorporable catalysts having functional groups (-OH, -NH-, -NH 2 ) or high molecular weight catalysts, since the commercially available, non-incorporable bismuth and tin catalysts with alkyl ligands in which less than There are 13 carbons that increase VOCs.

- Combinations of bismuth and tin catalysts are preferably used, with the bismuth catalyst used as the starting catalyst and the tin catalyst as the curing catalyst.
- the object of the invention was therefore to produce a lightfast polyurethane (PUR) material which has low VOC values, can be quickly demoulded, can be stored for a few days and can be produced inexpensively.
- the starting materials should be commercially available. To save costs, the components must be quickly demoldable. It is necessary that the reactive starting materials for the production of polyurethanes set quickly and already have a certain hardness when they are removed from the mold. On the other hand, however, a certain, not too short start time is needed to complete the tool completely. This should be "
- the setting time should preferably not be less than 30 seconds.

- the polyurethanes according to the invention have starting times of> 20 seconds and setting times of> 30 seconds.
- the starting time in the production of polyurethanes is the time which indicates the period from the mixing of the reaction components to the optically detectable reaction.
- the setting time defines the time required from the mixing of the reaction components to the solidification of the surface. To complete a tool completely, the setting time should not be too small.
- the curing of the material in the core is important in order to be able to demold easily, otherwise the component can warp.
- the curing of the material is determined by means of the penetration measurement. This is determined with a penetrator (for example, the Cone Penetrometer H-4236 Humboldt) at 1400 g load and a rounded penetration tip with a diameter of 2.5 mm 60 seconds after mixing at room temperature, the penetration depth. Small values stand for a good through-cure, large values for a bad sales / through-hardening.
