Functional barrier coatings are used extensively on packaging materials as well as those used for serving and presenting food, such as take-out boxes and paper plates. These coatings resist penetration by oil and grease, help maintain package integrity, and protect the consumer from unwanted stains. Barrier coatings can be for direct and indirect food contact, and may require FDA or BfR compliance. Barrier coatings on food packaging can also help extend shelf life.
Rovene 4100 is a styrene-butadiene emulsion polymer recommended for use for boxboard coating, in some publication grade papers and in the adhesive industry.
Rovene 4049 is a carboxylated styrene-butadiene emulsion that has a medium hand with above average strength properties. Rovene 4049 is recommended for use in a variety of applications including specialty paper coatings, textile and nonwovens, adhesives and paper lamination where high water and grease resistance films with low moisture vapor transmission is needed.
Rovene 4002 is a medium-firm, carboxylated styrene-butadiene emulsion designed to have good freeze-thaw stability and low odor characteristics, when used in trade sales coatings.
Tykote 1004 is a low surfactant styrene-butadiene emulsion polymer designed as a base resin for functional coatings. Tykote 1004 can be used to compound functional coatings exhibiting superior water, water vapor, oil and grease repellency.
Rovene 4019 is a styrene-butadiene emulsion polymer recommended for use in paper and paperboard coatings where a high degree of grease, oil and water resistance is needed.
Tykote 1019 is a carboxylated styrene-butadiene emulsion that has a firm hand with excellent film strength properties. It is intended for use as a base polymer in the formulation of barrier coatings for paper and paperboard packaging.
Tykote 6152 is a hard film forming styrene-acrylic emulsion designed for oil and grease resistant barrier coatings. This product also provides excellent water and blocking resistance in barrier coating compounds.
