MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202617031888 A) filed by Sika Technology AG on March 17, 2026, for Curable Compositions Containing Functional Polyethers And Aldimines.
Inventors include Scheurer, Rouven; Hberle, Hans; and Burckhardt, Urs.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: The invention relates to a curable composition comprising: at least one polyether polymer A with ketoester groups of formula (I) or aldimine groups of formula (II), having an average functionality of 1.7 to 3.0 and an average equivalent weight of at least 500 g/eq; at least one compound B with ketoester groups of formula (I) and an equivalent weight of 114 to 250 g/eq; and at least one aldimine L with aldimine groups of formula (II) and an aldimine equivalent weight of 110 to 350 g/eq, the ratio between the number of ketoester groups of formula (I) and the number of aldimine groups of formula (II) being between 2 and 3. The composition is free from toxic ingredients, not sensitive to moisture, and cures under ambient conditions without emissions and unpleasant odours to form an elastic polymer with high extensibility and surprisingly high tear resistance. The composition is particularly suitable as an elastic adhesive, sealant, or coating.
