MOISTURE CURING SILICONE ROOF COATING 

670HS KARNA-SIL ULTRA BY KARNAK 

KARNAK 670HS Karna-Sil Ultra is a white, low-VOC single component, moisture curing silicone roof coating that produces a durable elastic coating with exceptional weathering and water resistance characteristics.  

The cured silicone coating provides a proven solution for renewing weathered roofs and can be applied to virtually any existing roof system to create a seamless water-resistant membrane for superior protection against ponding water, UV light and severe weather. It’s ENERGY STAR-rated, helping buildings qualify for LEED Certification. When properly installed, the coating may help keep interior building temperatures cooler and potentially reduce building operating costs. Learn more at karnakcorp.com  

SILICONE ROOF COATING SYSTEM PRIMER 

MULTIBASE SB BY MULE-HIDE PRODUCTS CO. 

Mule-Hide Products Co. has expanded its Silicone Roof Coating System with Multibase SB, a new primer that delivers stronger adhesion and prevents asphalt bleed-through in non-ponding water conditions. Multibase SB is a one-part, 100 percent acrylic based resin intended for use as a primer prior to the application of Mule-Hide 100 percent Silicone Roof Coating. It can be used on modified bitumen, asphaltic built-up roofing, EPDM, Hypalon and PVC roof surfaces. The primer contains minimal pigment and no mineral fillers, enhancing its adhesion to the roof surface. In addition, its relatively thin viscosity and low surface tension allows the primer to completely saturate the roof surface, further helping form a strong bond. For more information, visit mulehide.com  

SILICONE AND ACRYLIC COATINGS 

ASLAN® COATINGS BY SOPREMA® INC. 

SOPREMA Inc. has launched a new collection of silicone and acrylic products under the brand name of 

ALSAN® Coatings. They’re ideal for maintaining and extending the life of existing roofs by protecting them from natural weathering. 

The ALSAN Coatings line is comprised of: 

• ALSAN Coating SIL 402, a low-VOC, high-solids, single-component silicone roof coating that forms a durable weatherproof coating for exceptional UV protection and resistance to standing water. 
• ALSAN Coating AC 401, a VOC compliant, high-quality, plasticizer-free, water-based acrylic elastomeric roof coating that is tested in accordance to ASTM D-6083.

ROOFSHIELD® I.S. FAST-DRY ELASTOMERIC ACRYLIC COATING 

UNITED COATINGS™ 

RoofShield® I.S. Fast-Dry Elastomeric Acrylic Coating is an acrylic polymer dispersion system that is designed to rapidly form a film that resists rainwater wash-off. RoofShield® I.S. advantages include: 

• Resistant to rainwater wash-off in as little as 15 minutes 
• 92 percent faster dry-to-touch time than traditional acrylic coatings 
• 50 percent faster dry-to-touch time than traditional low solids silicone 
• Apply up to 60 wet mils in a single pass! Visit gaf.com for more information. 

FLUID-APPLIED MEMBRANE 

LIQUITEC™ BY GARLAND 

Garland’s newest fluid-applied membrane is a tough, virtually odorless, easy-to-apply restoration coating for aged roofs. 

LiquiTec™ is built to provide watertight performance while also protecting roof surfaces from harsh weather and other impacts. Garland’s first ever fluid-applied seamless membrane, LiquiTec, forms a virtually impenetrable surface over aged modified bitumen, metal and single-ply roof systems, adding years of waterproofing protection. Unlike common aromatic polyurethane coatings that chalk and degrade when exposed to UV, LiquiTec is an aliphatic polyurea coating system with a tightly bonded molecular structure that provides strength and durability similar to truck bed liners. LiquiTec is built to protect roof surfaces from damage caused by hail, foot traffic, wind scour and other impact.

ROOF COATINGS EARN ICC-ES VERIFICATION 

POLYBRITE® BY POLYGLASS U.S.A. INC. 

Polyglass U.S.A., Inc. announced that PolyBrite® 70, PolyBrite 71-HS, PolyBrite 75, and PG 700 elastomeric roof coating systems meet code requirements according to an independent ICC Evaluation Service Report (ESR-4038). 

PolyBrite and PG elastomeric coating systems are ideal for polyurethane foam, modified bitumen, plywood, concrete and most metal roofing substrates. PolyBrite 70, PolyBrite 71-HS, PolyBrite 75 and Polyglass PG 700 elastomeric roof coatings offer ultraviolet energy resistance and fire protection through their proprietary formulations utilizing 100 percent acrylic resins. 

These coatings cure to form a seamless fluid-applied roof membrane to extend the useful life of the roof. Each system provides tensile strength and elongation, as well as resistance to fungus, algae, and dirt pickup. For more information, visit.polyglass.us  

COLD LIQUID-APPLIED MEMBRANE ROOFING AND WATERPROOFING SYSTEM 

KEMPEROL® BY KEMPER SYSTEM 

Architects and other commercial roof specifiers can protect and accent flat and low-slope roofs with a new Kemperol® cold liquid-applied membrane roofing and waterproofing system. Kemperol 2K-FR is derived from the successful, bright white Kemperol Reflect 2K-FR resin system. Kemperol 2K-FR is fully reinforced and features “thru color”: It does not need a color topcoat because the resin is tinted throughout. Designed for extending the life of new or existing low-slope roofs, the Class A fire-rated, odor-free polyurethane resin (PUR) system is now available in Stone Gray or Patina Green. For roof projects that can benefit from a high Solar Reflectance Index (SRI) roofing, Kemper System offers two cool-roof membrane systems — Kemperol Reflect 2K-FR (SRI 110), a PUR, and Kemperol AC Speed (SRI 108), a PMMA.
