There are many packaging materials and applications that require a functional coating to perform as a moisture barrier, to seal in freshness and keep out moisture or humidity. Also known as low moisture vapor transmission coatings. The MVTR measures the effectiveness of the moisture barrier to prevent water vapor from being transmitted from one side of the paper or packaging to the other. This low MVTR coating helps to provide protection, ensure a longer shelf-life, and better product and package integrity.
MCP’s Tykote latexes are part of a full line of proven products designed to give various combinations of barrier properties including low MVTR. These products are designed to be used in finished coatings by themselves or in combinations with other ingredients.
Tykote 1005 is an anionic, carboxylated styrene-butadiene copolymer latex designed for use in functional coatings. Tykote 1005 is designed as a base resin for functional coatings.
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.
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 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 4119 is a styrene-butadiene emulsion recommended for use in paper and paperboard coatings where excellent water vapor transmission resistance is needed.
Rovene 4009 is a styrene-butadiene emulsion polymer recommended for applications in specialty paper coatings where water, grease and oil resistance is needed.
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.
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.
