Exterior Architectural Coatings
Resins and additives that improve exterior coatings
Exterior architectural coatings have to satisfy several demands at once: customer specifications, consumer expectations, and evolving sustainability goals.
Our portfolio gives formulators the binders and additives to create exterior wall and trim paints that protect surfaces through prolonged exposure to the elements, while staying easy to apply and good to look at.
And we keep innovating to support more sustainable paints without sacrificing durability.
Explore exterior architectural coatings
Exterior wall and trim paints, primers, stains and sealers all rely on the same core materials, and our portfolio covers each one. Acrylic emulsion binders form the protective film that stands up to rain, UV and temperature swings, while rheology modifiers, dispersants, and silicone additives control how the paint flows, disperses pigment and weathers over time. Explore our exterior architectural coatings materials below to see how each one fits into your formulation.
RHOPLEX™ Emulsions
These 100% acrylic emulsion polymers are designed for use in high-performance exterior architectural coatings. They are widely recognized for their versatility, durability, and ability to meet stringent environmental standards.
EVOQUE™ Emulsions
Our 100% acrylic pre-composite binders are ideal for premium architectural coatings, including exterior wall paints. Their unique technology surrounds pigment particles—especially titanium dioxide (TiO₂)—creating a polymer-pigment matrix that dries to a tighter film with a polymer-rich surface.
ACRYSOL™ Rheology Modifiers
ACRYSOL™ Rheology Modifiers deliver precise viscosity control for paints, ensuring smooth application, sag resistance, and excellent film build across a wide range of architectural coatings.
TAMOL™ Dispersants
TAMOL™ Dispersants provide superior pigment dispersion and stability in waterborne coatings, improving color development, gloss, and formulation efficiency for high-quality architectural paints.
DOWSIL™ Additives
Our silicone-based performance enhancers are designed for use in waterborne and solventborne exterior wall paints. They are engineered to deliver a range of benefits that improve the durability, appearance, and application properties of architectural coatings.
Explore common applications for exterior architectural coatings
Exterior architectural coatings do more than add color. The applications our materials support most often include:
- Wall and facade paint for broad, weather-exposed surfaces
- Trim and accent finishes that need gloss and block resistance
- Primers and sealers for adhesion and stain blocking
- Masonry, stucco and concrete coatings that resist alkalinity
- Wood coatings and stains for siding, decks and fences
- Elastomeric coatings for crack bridging and waterproofing
Exterior Façade Wall Paint
Our exterior facade wall paint solutions stand out for their durability, versatility and sustainable properties. Whether you need advanced binders, innovative additives, or digital formulation tools, Dow offers a comprehensive portfolio to help deliver high-performance, long-lasting facade coatings.
Exterior Primer
Our exterior primer solutions offer reliable adhesion, stain blocking, water and alkali resistance, and long-term durability—while supporting sustainability and regulatory compliance. These technologies help formulators create primers that protect and enhance the performance of exterior coatings.
Formulation solutions
Different exterior projects call for different formulations. A coastal facade fighting salt and UV asks something different of a coating than a primer over fresh masonry or a stain on a cedar deck. Our portfolio gives you the range to meet those needs, from acrylic binders and rheology modifiers to dispersants and silicone additives you can dial in for durability, appearance and easy application. Pair them with DOW™ Paint Vision and work with our specialists to move from a performance target to a working formulation faster.
