A) at least one metal passivator that forms a protective film on steel and B) at least one carbonic acid neutralizer which is an organo amine and C) at least one film forming corrosion inhibitor which is a C1-4 dialkylamide of the formula R R1NH, wherein R and R1 are each independently C1-4 alkyl.
- 15. A mixture as in claim 13 which contains an additional additive selected from preservatives, biocides, anti-foaming agents, surfactants and flame retardants.
- 16. A mixture as in claim 13, wherein said at least one oxygen scavenger(s) that bind dissolved oxygen within an aqueous carrier is diethylhydroxylamine, a sulfite, a hydrazine, a tannin, carbohydrazide or a mixture thereof.
- 17. A mixture as in claim 13, wherein said at least one oxygen scavenger(s) that bind dissolved oxygen within an aqueous carrier is diethylhydroxylamine.
- 18. A mixture as in claim 13 which provides release properties to lignocellulosic materials on metal at levels from 0.1-1.0 milligrams of solids/cm2 of surface area.
- 19. A mixture as in claim 13 wherein the release agent comprises:
a) an alkali metal salt of a tall oil fatty acid and b) an additional wax or oil.
- 20. A mixture as in claim 19, wherein said alkali metal salt of a tall oil fatty acid is a potassium salt.
- 21. A mixture as in claim 19, wherein the wax is polyethylene glycol or ethylene bisstearamide.
- 22. A mixture as in claim 19, wherein the wax is a natural wax.
- 23. A mixture as in claim 19, which contains an additional additive to enhance the release properties selected from polishes, silicones and polytetrafluoroethylene.
- 24. A mixture as in claim 19, wherein the oil is a vegetable oil.
- 25. A release agent as in claim 24, wherein the vegetable oil is castor oil.
- 26. A mixture as in claim 19, which contains an additional additive selected from preservatives, biocides, anti-foaming agents, surfactants and flame retardants.
- 27. A method of using the mixture of claim 18, comprising applying said release agent to the surface of a mold or platen.
- 28. A method for the manufacture of molded articles comprising applying to a mold surface, a mixture of claim 18; and molding lignocellulosic material or concrete or polyurethane foam in said mold.
