February, 2013 - Less Heat Transfer into Buildings Voted as the Main Benefit of IR-Reflective Coatings
Coating materials exposed to sunlight absorb the emitted incident energy and convert the sunlight into heat; this absorbed heat can then degrade the protective coating as well as the substrate below the coating. Recent advances in infrared (IR) reflective pigmentation technology now enable protective coatings, such as roof coatings, to reflect incident energy from sunlight, thus lowering the temperature of the coating and extending the lifetime of the coating and substrate.The incident energy of sunlight striking a surface consists of approximately 5% ultraviolet energy, 42% visible energy and 53% near infrared energy (the actual amount will vary depending upon time of day and weather conditions). Infrared reflective pigmentation technology utilizes pigments that absorb color in the visible light energy range while reflecting near-infrared (NIR) energy emitted from the sun. Reflection of the near-infrared incident energy reduces the temperature of the coating and substrate by lowering the energy absorption from the sunlight.
January, 2013 - Zinc Phosphate Voted as Most Promising Anti-corrosive Pigment for Coating Protection
Organic coatings provide a protective barrier film for metal substrates. However, organic coatings are not impervious to moisture and do not provide corrosion resistance. When moisture penetrates through the coating and comes in contact with the metallic surface, the metallic surface can undergo corrosion. One of the options to protect the metal surface from corroding is to incorporate anti-corrosive pigments into the coating. For example, zinc phosphate provides corrosion protection to steel substrates via the following mechanism: zinc phosphate (Zn3(PO4)2) hydrolyzes in water to produce zinc ions (Zn2+) and phosphate ions (PO43-). The phosphate ions act as anodic corrosion inhibitors by phosphating the steel and rendering it passive. The zinc ions act as cathodic corrosion inhibitors. Corrosion protection is also important to prevent loss of adhesion (blistering) between the paint and metal surface.
