Lubrizol innovates and markets a robust portfolio of resin and binder technologies for coatings, including acrylic dispersions, acrylic emulsions, PVC emulsions, PVDC emulsions, polyurethane dispersions, solution acrylics, and vinyl acetate emulsions.
Acrylic dispersions are surfactant-free acrylic resins suspended in alkaline water. These resins are often used in coating formulations to impart robust performance benefits, including hardness, chemical resistance, and corrosion inhibition. Lubrizol works with customers to formulate customized acrylic dispersion solutions for advanced coatings that meet specific performance requirements. Carboset® acrylic resins from Lubrizol include a family of acrylic dispersions that are well-established in the coatings industry to bring robust, proven performance.
Acrylic emulsions are inherently UV-stable polymers made with monomers based on acrylic acid. The broad range of Tg values achievable makes these resins capable of forming very soft coatings suitable for pressure sensitive adhesives up to very hard, scratch and mar resistant coatings. Carboset® acrylic resins from Lubrizol include acrylic emulsions used in construction, industrial, wood and automotive applications. Hycar® acrylic resins bring properties such as flexibility, hydrophobicity/hydrophilicity control, and chemical resistance to paper, textile and synthetic applications. Carbobond™ acrylic resins include acrylic emulsions used as heat seal, cold seal, lamination, lidding and blister packaging adhesives, including products for broad food contact compliance. Carbotac™ acrylic resins are designed for formulating into pressure-sensitive adhesives suitable for labels, tapes, and graphic and protective films.
PVC emulsions are vinyl chloride acrylic copolymers well-known for chemical resistance, scrub and scuff resistance, and flame retardance. PVC emulsions are commonly used in paper, textile, composites and building material applications. Vycar™ vinyl chloride resins from Lubrizol cover a range of glass transition temperatures and chlorine contents. These PVC emulsions enable coating formulations with diverse hardnesses, and can be fine-tuned to the stiffness/flexibility requirements of a wide range of surfaces.
Polyvinylidene chloride (PVDC) emulsions are excellent barriers to oxygen and moisture, making them well-suited for use in anti-corrosion coatings for metal. Permax™ vinylidene chloride resins from Lubrizol provide outstanding corrosion resistance, coupled with the adhesion flexibility and durability necessary for metal coatings in industrial environments. They are fast-drying PVDC emulsions which allow greater process efficiencies, such as faster line speeds.
Polyurethane dispersions are resins supplied in water that bring a unique combination of toughness and durability typically not achievable in other polymer chemistries. These resins are used on a wide range of surfaces, including wood, metal, plastics, masonry and textiles. Sancure™ polyurethane dispersions from Lubrizol are used in coatings to bring tough, long-lasting durability to wood, metal and plastic surfaces, as well as softness, flexibility and scuff resistance to textiles. Turboset™ self-crosslinking polyurethane dispersions deliver the same coatings benefits in an easy-to-use, 1-K, lower VOC system. Aptalon™ polyamide technology includes a growing portfolio of polyurethane dispersions that rival solvent-borne, 2-K products.
Solution acrylics are acrylic polymers covering a broad range of glass transition temperatures and functionality. These resins are supplied in traditional hydrocarbons, such as toluene or xylene, as well as more environmentally friendly solvents such as Oxsol® 100. Solution acrylics are typically used in applications requiring the highest performance of outdoor durability, chemical resistance and hardness. Doresco® acrylic resins are solution acrylics designed for applications in printing, packaging, industrial metal, and specialty construction. In printing applications, Doresco acrylic resins are particularly useful for hot stamp foil, high vacuum metallizing and security printing applications. Many Doresco products are also functionalized to allow fine tuning for specific end use requirements.
Vinyl acetate emulsions are copolymers of vinyl acetate and acrylic monomers produced by emulsion polymerization. These resins provide a good balance of performance and cost and are typically used in adhesive applications such as heat sealing and bundle gluing or to build hand in fabric coatings and interior furnishings. Vycar™ vinyl chloride and vinylidene chloride resins from Lubrizol include a product line of vinyl acetate emulsions that meet customer requirements in the paper, textile, printing, packaging, paints and coatings markets. These products are available as both resin components and fully formulated products.
