BASF Roofing
The controlled flow properties of the coating allow a continuous, even film to be applied even over rough surfaces.
Once cured, Elastocoat 3-5000 Silicone Roof Coating forms a durable, flexible membrane that is integral with the structure itself. When properly applied, the cured coating provides a weather-tight seal that will protect polyurethane foam from degradation caused by weathering, aging, oxidation, wind-driven sand, rain and snow and the effects of ozone and ultraviolet radiation. The membrane remains flexible even after exposure to temperature extremes typically seen on roofs. Supplied as a one-part, ready-to-use material, it is available in four fade-resistant colors including light gray, beige and white; and a dark gray normally applied as basecoat.
The cured silicone rubber membrane is vapor permeable, having the ability to "breathe," and thus reduces both the chances of blistering caused by vapor pressure in the substrate and the possibility of damage to the substrate caused by entrapped water.
Product Description:
ELASTOCOAT 3-5000 Silicone Roof Coating is a moisture-cure silicone rubber roof coating system designed for use over spray-in-place polyurethane foam. ELASTOCOAT 3-5000 is a key component in warranted roofing systems.

How to Use:
When properly applied and cured, Elastocoat 3-5000 Silicone Roof Coating provides one of the fastest, easiest and most effective methods of keeping polyurethane foam roofs weather resistant. For best protection, apply the full polyurethane foam thickness and silicone basecoat the same day. Apply at temperatures above 40°F (4°C). Thinning, when authorized by BASF, and clean up should be accomplished with VM&P Naptha ONLY.
Preparation:
Surfaces to be coated with Elastocoat 3-5000 Silicone Roof Coating must be prepared and the coating applied as described in BASF printed instructions and guide specifications. All surfaces must be clean, dry and frost-free. Elastocoat 3-5000 Silicone Roof Coating is applied in two coats of contrasting colors at a rate of at least 1¼ gallons per 100 square feet for each coat, using the material as supplied. Apply using conventional, airless spray equipment (a medium-nap, solvent-resistant paint roller or brush may be used for touch-up work). Cure time for each coat may vary from 2 to 6 hours, depending on temperature and humidity. The minimum combined cured thickness of basecoat and topcoat must be 15 mils, unless a greater thickness is required by the Special Warranty selected. Optional application of #11 standard roofing granules may be made according to BASF printed instructions to improve impact and wear resistance, to provide non-slip service walk areas, or for enhanced aesthetics.
Maintenance:
The life of a roof may be extended by regularly scheduled maintenance. A roof should be inspected at least twice a year and immediately following severe weather, extraordinary maintenance or work on roof-mounted equipment. If the coating becomes damaged, refer to BASF's Owners Manual and specifications for repair information.
Usable Life and Storage, Packaging, Limitations:
Elastocoat 3-5000 Silicone Roof Coating has a minimum shelf life of 6 months from date of manufacture, refer to product packaging for date of manufacture. It is available in 50-gal (189-l) containers, and should not be used on the outside of cold vessels, coolers or freezers without an additional vapor retardant coating. This product is neither tested nor represented as suitable for medical or pharmaceutical uses.
Health and Environmental Information:
BASF has an extensive Product Stewardship organization and a team of Product Safety and Regulatory Compliance (PS&RC) specialists available in each area. Consult MSDS and/or your local BASF representative.
Limited Warranty Information - Please Read Carefully:
Various Special Warranties may be purchased form BASF Corporation. These include Full System Limited Warranties and Coating-Only Limited Warranties. The special warranties are available only when the roof system is applied by a BASF Approved Applicator in strict accordance with BASF's application specifications for the particular warranty package selected. If no special warranty is purchased, BASF's Standard Product Warranty applies. For details on all available warranties, contact your BASF Roofing Specialist.
