AQUEOUS OR WATER-DILUTABLE BLOCKED POLYISOCYANATES AND THEIRUSE FOR PREPARING POLYURETHANE CLEARCOATS HAVING SUBSTANTIALLY REDUCED THERMAL YELLOWING |
| 摘要 |
The present invention relates to novel aqueous or water-dilutable blocked polyisocyanates and to their use for the production of one-component polyurethane coating compositions, which are stovable at relatively low temperatures of 130 to 150~C and provide clear coatings having substantially reduced thermal yellowing.
