The paper industry uses many different types of synthetic emulsion polymers: Carboxylated styrene-butadiene latex, styrene acrylic copolymers, acrylic polymer emulsions, and vinyl acetate containing emulsions are all used at various stages of papermaking and paper coating. These chemistry options are also used widely in the Packaging sector.
Functional barrier coatings, which resist penetration by water, water vapor, oil and grease, can be applied at the paper machine or converter. Barrier coatings used on packaging paper and paperboard protect the product and help extend shelf life. MCP also supplies many water-based solutions for inks and coatings used in printing to provide protective and aesthetic value.
For masking tape and many other applications, emulsion polymers are used for saturation to increase strength and water or chemical resistance. For masking tape, release paper is often used in conjunction with a PSA, so the tape needs a coating with completely different characteristics. Rather than bonding, the coating must prevent a bond from forming. MCP manufactures polymer products that help provide this low-energy type of surface coating. MCP also has products specific to wet-end or beater addition. These grades are used in the papermaking process.
