Release Agents Containing Saponified Fatty and Rosin Acids or Derivatives Thereof
The invention relates to compositions useful as release agents containing saponified fatty and/or rosin acids, as well as methods of making and using the same.
1 . A release agent composition, comprising:
a soap component comprising a saponified component comprising: (i) an at least partially saponified saturated or unsaturated, monocarboxylic aliphatic hydrocarbon or derivative thereof having a linear, branched, and/or cyclic chain, a dimer thereof, a trimer thereof; or (ii) an at least partially saponified mixture of rosin acids; and,
a release enhancing component;
wherein the saponified component is present in an amount that is from 1 to 50 wt % based upon the total weight of the composition.
2 . The composition according to claim 1 , wherein the saponified component is present in an amount that is from 3 to 20 wt % based upon the total weight of the composition.
3 . The composition according to claim 1 , wherein the saponified component is present in an amount that is from 5 to 15 wt % based upon the total weight of the composition.
4 . The composition according to claim 1 , wherein the saponified component is present in an amount that is from 1 to 10 wt % based upon the total weight of the composition.
5 . A release agent composition, comprising
from 8-15 wt % of saponified distilled tall OIL; and, from 10 to 20 wt % alkyl ester of fatty acid or polymeric glycol fatty acid.
6 . A mold construct, comprising
a mold;
a moldable material; and
a release layer positioned between the mold and the moldable material, wherein the release layer comprises:
a soap component comprising a saponified component comprising: (i) an at least partially saponified saturated or unsaturated, monocarboxylic aliphatic hydrocarbon or derivative thereof having a linear, branched, and/or cyclic chain, a dimer thereof, a trimer thereof; or (ii) an at least partially saponified mixture of rosin acids; or, a release enhancing component;
wherein the saponified component is present in an amount that is from 1 to 50 wt % based upon the total weight of the composition.
7 . The mold construct according to claim 6 , wherein at least a portion of the release layer is contact with at least a portion of the mold.
8 . The mold construct according to claim 7 , wherein at least a portion of the release layer is contact with at least a portion of the moldable material.
9 . A method of making a molded article, comprising
removing a molded article from a mold construct once the moldable material has at least partially dried and/or solidified, wherein the mold construct comprises:
a mold;
a moldable material; and
a release layer positioned between the mold and the moldable material,
wherein the release layer comprises:
a soap component comprising a saponified component comprising: (i) an at least partially saponified saturated or unsaturated, monocarboxylic aliphatic hydrocarbon or derivative thereof having a linear, branched, and/or cyclic chain, a dimer thereof, a trimer thereof; or (ii) an at least partially saponified mixture of rosin acids; or,
a release enhancing component;
wherein the saponified component is present in an amount that is from 1 to 50 wt % based upon the total weight of the composition.
10 . A molded article made from the process according to claim 9.
