Elastuff™ 101 & Elastuff™ 103 is a high solids, moisturecatalyzed, single-component polyurethane coating system.
The system consists of Elastuff™ 101, an aromatic polyurethane basecoat, and Elastuff™103, a UV-resistant, color
stable aliphatic polyurethane topcoat. Elastuff™ 103 is a low VOC aliphatic topcoat available to meet VOC regulations
in specific areas. This combination provides an excellent balance of tensile strength, elongation and hardness, resulting in superior durability,
dirt and mildew resistance, chemical resistance and weatherproofing. High abrasion and impact resistance also offer protection from maintenance traffic and
severe weather conditions.
Elastuff™ 101 & Elastuff™ 103 system is a permanently flexible “breathing” membrane, allowing moisture vapor to pass through the film while preventing water infiltration.

The Elastuff™ 101 & Elastuff™ 103 System is designed for protecting a wide range of substrates from the
effects of weathering and moisture intrusion. It is particularly effective as a protective membrane over new or existing roof substrates,
including concrete, metal, polyurethane foam, and asphaltic substrates. It provides a barrier to the effects of degradation caused by normal
weathering, aging, and ultraviolet exposure.
Elastuff™ 101 & Elastuff™ 103 is also effective when used on other horizontal or vertical applications requiring a tough, abrasion, and chemical-resistant membrane, such as secondary containment and hot or ambient storage tanks.
The Elastuff™ System also achieves excellent adhesion to primed concrete, masonry, metal and wood surfaces. Elastuff™103 is very effective when used on its own in a wide variety of applications requiring a tough, abrasion resistant finish.
Elastuff™ 101 and Elastuff™ 103 are single-component elastomers that are catalyzed through exposure to moisture in the air. They are designed for application through standard airless spray equipment.
Elastuff™ 101 is available in standard Light Gray only. Elastuff™ 103 is available in standard White, which is certified to meet ENERGY STAR®, Cool Roof Rating Council (CRRC) and LEED reflectance and emissivity criteria, as well as California Title 24 requirements.

Properties & Advantages
Resistance to Accelerated Weathering: Test panels were placed in the QUV Accelerated Weathering Tester. Cycling is set at 4 hours of ultraviolet radiation, during which
time temperatures reach approximately 135°F (57°C), and 4 hours with no U.V. radiation. A water bath at the bottom of the unit is maintained at 100°F (38°C) to create
a constant high humidity condition. After 3,000 hours of continuous testing, the Elastuff™ 101 & Elastuff™ 103 system showed no
surface checking or cracking, no delamination, no loss of flexibility and no chalking. Tested in accordance with ASTM G53.
Resistance to Freeze-Thaw: Elastuff™ 101 & Elastuff™ 103 test panels were exposed to freeze-thaw cycles under complete immersion in deionized water. Cycles consisted of 16 hours at 0°F (-18°C) and 8 hours at 70°F (21°C). After 4 complete cycles, the physical integrity of the coating remained unaffected. There was no loss of adhesion, and no blistering or softening.
Water Absorption: 3” (7.5 cm) free film discs were immersed in deionized water at 70°F (21°C). After 7 days immersion, Elastuff™ 101 showed less than 1% weight gain, while Elastuff™
