Surfactants for Emulsion Polymers

The terminology, surfactant is a connected word, appropriately derived from surface-active agent.  While used in an extensive range of industries, this blog post will focus on the use of surfactants in the CASE industry segment, where our products are applied in emulsion polymerizations and as stabilizers, dispersants, wetting agents and foam modifiers.  The main functions of surfactants in water-based CASE applications are to emulsify water-insoluble, hydrophobic monomers to facilitate polymerizations in anemulsion state, and to stabilized suspensions of the resulting synthetic polymers so they can be stored, formulated and subjected to shear forces.

Vinyl Acrylic Binders & Resins

Vinyl acrylic binders and resins are economical products that find extensive usage in interior architectural paints and caulks, adhesives and sealants, paper and textile binders, paper saturants, engineered fabrics, and pigment dispersions. With the unlimited variability in monomer options and copolymer ratios, vinyl acetate-acrylic copolymer binders allow the design of products with a wide spectrum of cost and performance profiles.  The role of the binder resin is to bind the pigments into a tough, continuous film and to promote the adhesion to the substrate surface while resisting wear and blistering etc.  Vinyl acetate monomer achieves cohesive strength in a binder at a low cost, while acrylic monomers like butyl and 2-ethylhexyl acrylates enhance the performance of copolymers by improving flexibility, water resistance, adhesion, scrub, and stain resistance and outdoor weathering.

Durable, Ambient Temperature, Self Crosslinkable Acrylic Emulsions Based on DAAM/ADH

The leading crosslinking technology for acrylic emulsion polymers is ambient temperature crosslinking chemistry based on diacetone acrylamide (DAAM) and adipic acid dihydrazide (ADH) monomers. This technology, known as “keto-hydrazide crosslinking,” involves the direct reaction of the pendant ketone moiety on the DAAM-acrylic polymer segment with the hydrazide moiety of the ADH, with the evaporation of water in the film-forming process. 

The highest adoption of this ambient temperature, self-crosslinking technology has been in high-durability paints and coatings for architecture, wood and concrete surfaces, and more. The DAAM/ADH pair is also used in crosslinkable sizing agents, thickeners, adhesives, and sealants.

Methyl Acrylate:  A Special Acrylic Monomer

Methyl acrylate (MA) is the fourth most-used of the basic acrylic esters for production of acrylic and vinyl-acrylic resins, surpassed only by butyl acrylate, ethyl acrylate and 2-ethylhexylacrylate.  As the lowest-molecular weight member of the homologous acrylic ester family, MA also finds uses as a starting material for the synthesis of other acrylates and derivatives ( these often involve transesterification reactions, or “Michael Additions” to the acrylic double-bond).

Vinyl Acetate Monomer (VAM):  A Highly Versatile Polymerization Intermediate

Vinyl acetate monomer (VAM) is a significant intermediate used in the production of a wide range of resins and polymers for paints & coatings, adhesives, glues & sealants, elastomers, textile finishes, paper coatings, binders, films, and a myriad of other industrial and consumer applications.  It efficiently homo-polymerizes to polyvinyl acetate (PVA),  and VAM can be used in numerous random copolymers and terpolymers such as ethylene-vinyl acetate copolymers, vinyl-acrylic resins, vinyl acetate-acrylic acid copolymers, and vinyl acetate-vinyl chloride copolymers.  With the wide diversity of polymerization options, VAM has allowed the design of products with a wide spectrum of cost and performance profiles.
