Environmental
Sunshield 3800 is water-based for easy cleanup and low odor. It contains low VOCs to keep our air clean. Because of its hardness, Sunshield 3800 requires few anti-microbial agents. Also, Davlin products contain no zinc additives and have a low erosion rate, which contributes to cleaner waste water in our streams, rivers, lakes, and bays.
Reflectance Characteristics
Sunshield 3800 is ultra-reflective in the 300-1200nm CIGS Photovoltaic (PV) spectrum. At the same time, 3800's pigments safely absorb over 80%6 of the sun's UV, reflecting less than 20% upward. This reduces UV expo- sure to solar photovoltaic hardware, and may slow degradation. Sun- shield 3800 was specifically engineered to be dirt resistant and durable, at the lowest cost per square foot and per Watt-peak. Sunshield 3800 is highly resistant to microbial growth and requires few anti-microbial addi- tives. By comparison, other coatings require massive amounts of biocide, which leach out and become ineffective within 3-5 years. CIGS Reflectance: 98% initial and 94% settled.

- Applications & Uses
Installation
Flush all equipment with water before use. Stir Sunshield 3800 thoroughly until uniformly blended, but avoid excessive mixing to prevent air entrapment. Thinning is not recommended.
Spray or Roller application
Apply a wet coat in even, parallel passes, overlapping each pass 50 percent to avoid holidays, bare areas, and pinholes. Clean equip- ment with water or water/detergent immediately after use. Drying time at 75°F and 50% Relative Humidity is 1-2 hours to dry hard for next coat, and 2 weeks until full cure.
Equipment
The following is a guide; suitable equipment from other manufacturers may be used. Changes in pressure and tip size may be needed for proper spray characteris tics.
- Airless: Standard equipment such as Graco Series 600. Tip sizes from 0.018 -0.021.
- Conventional: Industrial equipment such as DeVilbiss, MBC, or JGA spray gun. Separate air and fluid pressure regulators and a moisture and oil trap in the main air supply lines are recommended.
- Brush/Roller: Suitable for waterborne coating. All surfaces should be clean, free from dirt, release agents, wax, mildew, and all other contaminants, including salt deposits.

Safety & Health
- Cautions & Limitations
Caution
Sunshield 3800 has extremely high sunlight reflec- tance. Wear tinted sunglasses that filter out ultraviolet light when servicing highly reflective roof surfaces. Roofing and solar technicians should wear appropriate clothing and sun- Screen to protect skin from the sun, including skin exposed to reflected light from below
Limitations
Do not use Sunshield 3800 on surfaces subject to hot tires, or that are constantly under water. Do not apply during-nor 24 hours preceding-inclement weather including rain, fog, mist, or freezing temperatures. Do not use unless the air and surface temperatures are above 50°F and will remain at or above that temperature for at least 4 hours after completion of application. Keep material from freezing.
