Resin supported emulsions (RSEs), a subset of styrene-acrylic emulsion polymers, are emulsions built on an alkali soluble resin.Styrene-acrylic polymers also feature higher gloss, good weatherability and good stain resistance. A styrene-acrylic polymer, in contrast to an all-acrylic polymer, will have better water resistance yet will cost less to produce. Styrene-acrylic polymer emulsions are ubiquitous in every market where water-based systems are used because of the array of specific properties that can be achieved. These versatile compounds, like all polymers, can be created from a variety of different acrylic monomers to build a random copolymer with a specific glass transition temperature (Tg). Styrene-acrylic emulsion polymers are produced from styrene and acrylate esters (methyl methacrylate, butyl acrylate, 2-etylhexyl acrylate, acrylic acid and others).Acrylic polymer emulsions are notable for their good water, UV and heat resistance, higher solids, their ability to crosslink and good adhesion to low surface energy (LSE) substrates. Chemists can tailor acrylic polymer emulsions for a variety of end-use applications by combining the appropriate hard and soft monomers. Acrylic polymer emulsions are most commonly produced from methyl methacrylate, methyl acrylate, acrylic acid and butyl acrylate. Acrylic polymer emulsions are versatile synthetic polymer emulsions that can be built to achieve an array of properties.Some examples are moisture vapor barrier coatings for food packaging, carpet backcoatings, and liquid applied membranes for shower stalls. These unique properties make SB latex suitable for many applications requiring superior water resistance, good balance of tensile and elongation, excellent adhesion to difficult substrates, and high filler loading. Chemist can manipulate the polymer composition to create polymers with unique properties suited for the end-use application. Styrene-butadiene latex (SB latex) has a high crosslink density that gives it toughness, strength, and elasticity.The scientists at Mallard Creek Polymers practice five different types of polymer emulsion chemistries - and unique products can be created within each of these polymer families.
#EMULSION POLYMERS FREE#
A synthetic emulsion polymer is created when the polymerization process takes place in water, using free radical emulsion polymerization. Homopolymers form from like monomers, and copolymers form from two or more different monomers - such as styrene and butadiene. Polymerization occurs when a number of chemical units, or monomers, are linked together by covalent bonds.
For example, waterborne coatings using emulsion polymers are the most widely used type of coating technology in the world. From barrier coatings on food wrappers to the pressure-sensitive adhesive of a sticky note to the liquid applied waterproofing membrane under shower tiles, these polymers are ubiquitous.
