Laminate comprising a carrier and a coating layer, wherein the coating layer is applied over at least part of the carrier, the coating layer comprising a polyester derived from an aliphatic polyalcohol with 2-15 carbon atoms and a polyacid, the coating layer having a thickness in the range of 10-4000 microns, wherein the aliphatic polyalcohol contains at least 50 mol. % of glycerol and the polyacid contains at least 30 wt. % of tricarboxylic acid. Optionally a second carrier may be applied over at least part of the coating layer. If so desired, a further coating layer is applied over at least part of the second carrier, with optional further carrier-coating stacks applied over the further carrier. Preferably the tricarboxylic acid is citric acid. The laminate according to the invention may be, e.g., a multiplex-type material. The laminate according to the invention has fire-retardant properties which makes it particularly suitable for use in applications where fire-retardancy is an issue.
A laminate comprising a carrier and a coating layer, wherein the coating layer is applied over at least part of the carrier, the coating layer comprising a polyester derived from an aliphatic polyalcohol with from 2 to 15 carbon atoms and a polyacid, the coating layer having a thickness in a range of from 10 to 4000 microns, wherein the aliphatic polyalcohol comprises at least 50 mol. % of glycerol and the polyacid comprises at least 30 wt. % of tricarboxylic acid.
A laminate comprising a stack of carriers with coating layers sandwiched between the carriers, and/or applied on at least one outer surface of the laminate, at least one of coating layer comprising a polyester derived from an aliphatic polyalcohol with from 2 to 15 carbon atoms and polyacid and having a thickness in a range of from 10 to 4000 microns, wherein the aliphatic polyalcohol comprises at least 50 mol. % of glycerol and the polyacid comprises at least 30 wt. % of tricarboxylic acid.
The laminate according to claim wherein the acid comprises at least 50 mol % of citric acid, optionally at least 70 mole %, optionally at least 90 mole %, or even or optionally-at least 95 mole %.
