Elastomeric Roof Coating White 4.75 gal APOC AP-2415 12'' x 12'' x 14.75'' in The APOC AP-2415 elastomeric roof coating is a high-build, fiber-reinforced acrylic formula engineered for long-term reflective protection on sloped and flat roofs with positive drainage. Its 87% solar reflectivity reduces roof surface temperatures by up to 50F, lowering cooling loads and supporting energy efficiency in residential and light commercial applications. Formulated to stretch up to 300%, it bridges hairline cracks and accommodates thermal movement in metal, concrete, tile, TPO, EPDM, and aged asphalt or acrylic systems?without blistering or delamination. The siliconized finish resists dirt pickup, maintaining reflectivity longer than standard white coatings. Features - 87% solar reflectivity and high emissivity for LEED and ENERGY STAR compliance support - 300% elongation accommodates substrate expansion/contraction across temperature cycles - Fiber-reinforced for enhanced tensile strength and crack-bridging performance (1/16" active cracks) - Siliconized surface resists dirt retention, preserving reflectivity over time - Water-based, low-VOC (50 g/L) formula?safe for re-coating and environmentally responsible - Bonds directly to clean, sound metal, concrete, tile, mod-bit, BUR, EPDM, TPO, and existing acrylic coatings - Fast drying: recoatable in 4?6 hours; full cure in 24?48 hrs (at 70F, 50% RH) - Seamless, monolithic membrane eliminates seams and fastener penetrations - Freeze-thaw stable (with proper storage); re-mixable after thawing - Compatible with APOC primers and reinforcement fabrics for warranted systems Specifications - Brand Name: APOC - Model Name: APOC AP-2415 - Part Number: AP-2415 - Product Type: Elastomeric Roof Coating - Base: Acrylic - Color: White - Sheen: Gloss - Container Size: 4.75 gal (net fill; labeled as 5 gal) - Coverage: ~50?75 sq ft/gal per coat (2 coats typical; 100?150 sq ft total per pail) - VOC Content: 50 g/L - Elongation: ?300% - Tensile Strength: ?200 psi - Application Temp: ?50F - Cure Time: 24?48 hrs (full) - Viscosity: 115?120 KU - Specific Gravity: 1.324 - pH: 8 - Flash Point: 247F - Water-Based: Yes - Freezeable: Yes (do not apply frozen) - Packaging Type: Plastic Pail - Product Dimensions: 12.0 x 12.0 x 14.75 in - Item Weight: 60.0 lb - Country of Origin: United States - UPC: 025056241559 - Global Trade Identification Number: 00025056241559 - Manufacturer: APOC (a subsidiary of Henry Company) Product Application This coating is used by roofing contractors and facility managers on residential and light commercial roofs?including metal barns, concrete patios, modified bitumen garages, and retrofitted EPDM or TPO low-slope roofs?where extended service life, energy savings, and leak prevention are priorities. It?s especially effective on south- and west-facing slopes prone to UV degradation and thermal stress. Applied in two coats (minimum 20 mils dry), it forms a seamless, flexible membrane that reflects heat, seals minor imperfections, and protects underlying substrates from ponding (on properly sloped surfaces). Common in warm-climate rehab projects and LEED-certified builds, AP-2415 delivers cost-effective, sustainable roof restoration?extending service life 5?10 years without full tear-off.
