PARALOID™ Resins

PARALOID™ Resins Offer the Solution Process Advantage

Dow uses a unique polymerization process for the manufacturing of solid grade PARALOID™ Resins. Unlike suspension polymerization processes used by other manufacturers, the Dow solution/extrusion process is surfactant-free1. The result is remarkable - a family of PARALOID™ Resins that are less water sensitive, offering exceptional wet film and resistance properties.

Maintain & Protect
Resistance to the destructive nature of the elements, including water, temperature cycles, UV light, and corrosive salts are essential performance properties for resins applied in industrial settings. PARALOID™ Resins offer convenience and key performance properties, including corrosion, chemical and impact resistance, excellent early water resistance and dry time, and gloss/color retention, as well as excellent weatherability, durability and flexibility. These benefits make PARALOID™ Resins an excellent choice for most maintenance and protective applications.

Concrete Results
Solvent-borne concrete coatings bring many advantages, including easy application, fast dry speed, and excellent color and gloss retention for protecting concrete from the elements. PARALOID™ Resins offer these high performance properties, as well as excellent water and efflorescence resistance and good exterior weatherability.

In a Dow industry comparison, PARALOID™ B-66 Acrylic Resin was tested alongside a competitive resin. Both were applied to cured concrete at 250 grams per square meter and placed outside, face-up, at an exposure station after 24 hours of dry time. After two months, the concrete blocks were brought back to the lab. Water spots were then applied to the coatings, and left to dry overnight.

Comparison Study
PARALOID™ Acrylic have been tested in a variety of market applications including concrete. In a Dow industry comparison, PARALOID™ B-66 Acrylic Resin was tested alongside a competitive resin. Both were applied to cured concrete at 250 grams per square meter. After 24 hours of dry time, the concrete was placed outside, face-up, at an exposure station. After two months, the concrete blocks were brought back to the tab. Water sports applied to the coatings, and left to dry overnight.

PARALOID™ B-66 Acrylic Resin exhibits trace whitening, acting as a powerful, efficiente sealer, preventing water from penetrating trough to the concrete. The competitive resin, on the other hand, exhibits, heavy whitening, or efflorescence in which water penetrates through the coatings film, dissoldinv salts in the concrete which rise to the surface. This is usuaaly accompanied by some loss of adhesion at these locations.

Refinish Resistance
Automotive coatings require resins that can withstand a variety of road conditions and unpredictable weather patterns, including snow, sleet, rain and sun. Dow solutions for automotive refinishing include a range of PARALOID™ Thermoplastic and Thermosetting Resins offering flexibility and fast property development. Specific properties include excellent early water resistance and dry time, corrosion resistance, gloss and color retention, and flexibility/impact resistance, making these resins an excellent choice for car exteriors and other transportation-related applications. Designed to react with certain cross-linking systems, PARALOID™ Thermosetting Resins offer exceptional chemical resistance and overall performance.

PARALOID™ Edge Isocyanate-Free Technology
PARALOID™ Edge Isocyanate-Free Technology from Dow Coating Materials offers a first in solvent-borne two-component (2K) urethane technology: a high performance, ambient crosslinking system that is isocyanate-free1 and formaldehyde-free2. When properly formulated, PARALOID™ Edge ISO-Free Technology offers convenience, cost efficiency, and an improved environmental, health and safety (EH&S) profile.

Long Pot Life, Short Cure Time
Two-component (2K) polyurethanes typically sacrifice cure time for pot life unless plural component application equipment is employed. PARALOID™ Edge Technology is distinctly different. In addition to isocyanate-free crosslinking, this novel urethane technology decouples formulation pot life from coating dry time.
