Abstract
Official abstract text for this publication.
The invention relates to hotmelt adhesives based on polyesters, having low VOC and fogging values. In particular, the invention is directed to a polyester based on polycarboxylic acids and di- or polyols, wherein the polyester including dicarboxylic acids of the formula HOOC—(CH2)x-COOH with x>10 and diols of the formula HO—(CH2)y-OH, with the proviso that at least 50 mole percent of the dicarboxylic acids, based on the total amount of polycarboxylic acid components, and at least 50 mole percent of the diols, based on the total amount of di- or polyols, satisfy the condition x+y>18, in hotmelt adhesives.
First claim
Opening claim text (preview).
The invention claimed is: 1. A hotmelt adhesive comprising polyesters based on polycarboxylic acids and di- or polyols, comprising dicarboxylic acids of the formula HOOC—(CH2)x-COOH with x>10 and diols of the formula HO—(CH2)y-OH, with the proviso that at least 50 mole percent of the dicarboxylic acids, based on the total amount of polycarboxylic acid components, and at least 50 mole percent of the diols, based on the total amount of di- or polyols, satisfy the condition x+y≥18. 2. The hotmelt adhesive according to claim 1 , wherein the hotmelt adhesive are thermoplastic hotmelt adhesive. 3. The hotmelt adhesive according to claim 1 , wherein the hotmelt adhesive are reactive hotmelt adhesive. 4. An article comprising the hotmelt adhesive according to claim 1 . 5. The article bond according to claim 4 , wherein the article is in the wood and furniture industry, in the automotive sector, in the construction industry, shoe industry and textile industry, or in window construction. 6. A sealant or a coating material comprising the hotmelt adhesive according to claim 1 . 7. The article according to claim 4 , wherein the hotmelt adhesive is used in one-pack or two-pack systems. 8. The sealant or a coating material according to claim 6 , wherein the hotmelt adhesive is used in one-pack or two-pack systems. 9. The hotmelt adhesive according to claim 1 , wherein x>12 and y>6.
