Abstract
Described herein is a barrier coating composition comprising an organic blend comprising a first component and a second component, the first component comprising latex polymer and the second component being selected from polyurethane emulsion, wax emulsion, and alkyd emulsion, wherein the first component and the second component are present in a weight ratio ranging from about 2:1 to about 20:1, and the latex polymer has a glass transition temperature of less than about 18° C.
Claims20
A barrier coating composition comprising:
- a liquid carrier in an amount ranging from about 5 wt. % to about 50 wt. % based on the total weight of the barrier coating composition;
- an organic blend comprising a first component and a second component, the first component comprising latex polymer and the second component being selected from polyurethane emulsion, wax emulsion, and alkyd emulsion;
- and
- alumina trihydrate;
- wherein the first component and the second component are present in a weight ratio ranging from about 2:1 to about 20:1;
- wherein the latex polymer comprises acrylic polymer;
- and
- wherein the latex polymer has a glass transition temperature of less than about 18° C.
A barrier coating composition comprising:
- a liquid carrier comprising water;
- a blend of a medium chain-stopped oil alkyd emulsion and metal-based catalyst drying agent;
- a silane adhesion promoter;
- and
- a first flame retardant comprising one or more of alumina trihydrate, calcium borosilicate, and zinc borate and a second flame retardant that is different than the first flame retardant, the second flame retardant comprising one or more of alumina trihydrate, calcium borosilicate, and zinc borate;
- wherein the first flame retardant and the second flame retardant are present at a ratio ranging from about 1:2 to about 2:1;
- wherein the chain-stopped oil alkyd emulsion and the adhesion promoter are present in a ratio ranging from about 20:1 to about 40:1;
- and
- wherein the liquid carrier is present in an amount ranging from about 5 wt. % to about 50 wt. % based on the total weight of the barrier coating composition.
A barrier coating composition comprising a blend of:
- an organic blend comprising a first component and a second component, the first component being different from the second component;
- a flame-retardant composition comprising a first flame retardant and a second flame retardant, the first flame retardant and the second flame retardant being different;
- wherein the first flame retardant and the second flame retardant are present in a weight ratio ranging from about 3:1 to about 1:3;
- wherein the first flame retardant comprises alumina trihydrate;
- and
- wherein the second flame retardant comprises one of calcium borosilicate and zinc borate.
