The AC Cool Roof Binder systems are based on Kynar Aquatec PVDF binders, developed by Arkema’s fluoropolymer group, and ENCOR Flex polymers from Arkema Coating Resins.
Currently three systems are available, allowing greater formulation flexibility across different applications:
- AC III Binder System – This system uses a Kynar Aquatec FMA-12 PVDF based topcoat and ENCOR Flex 187 all acrylic or ENCOR Flex 192 modified acrylic basecoat to provide the highest possible level of performance and durability. It is designed primarily for the most demanding cool roof coating applications.
- AC II Binder System – Utilizing a proprietary ENCOR Flex 187 all acrylic polymer or ENCOR Flex 192 modified acrylic latex, this base and topcoat system delivers excellent performance and meets ASTM D-6083, “Standard Specification for Liquid Applied Acrylic Coating Used in Roofing.”
- AC I Binder System – This ENCOR Flex 3186 styrene acrylic system provides a good mix of performance and value for less demanding applications.
PPG Industries’ coil and building products group has published the “Building Products Coil Coatings Color Guide”, an eight-page brochure featuring 100 coatings color samples categorized according to eight product lines and five resin chemistries.
The booklet highlights 30 individual colors, ranging from regal and bright white to charcoal and solar-reflective black, for DURANAR ULTRA-COOL polyvinylidene fluoride(PVDF) coatings, DURASTAR polyester coatings and Durastar SMP (silicone-modified polyester) coatings. There are five color samples each for Duranar ULTRA-Cool SUNSTORM coatings and three-coat Duranar XL ULTRA-Cool coatings.
ULTRA-Cool coatings by PPG are formulated with proprietary infrared (IR)-reflective pigments and resin technologies that deflect solar heat from buildings, enabling them to stay cooler and consume less energy for air conditioning.
The guide features 10 Duranar VARI-COOL coatings, which combine ULTRA-Cool coatings technology with color-changing polychromatic pigments, along with 10 DURAFORM BP coatings, which are part of a new line of next-generation engineered polyester-resin-based products. Readers also will find five color swatches each for ENVIRON waterborne acrylic coatings and PLASTICRON plastisol-based coatings.
PPG coil coatings are designed to meet a wide range of building applications, from high-end roof and wall panels for monumental buildings to industrial plants, agricultural buildings, garages, warehouses and other utilitarian structures. With their broad color range, PPG coil coatings provide durable, colorfast protection to soffits, gutters, heating and air-conditioning ducts, trim coil and rainware due to their exceptional hardness and resistance to abrasion, chalking, ultraviolet (UV) radiation, moisture, corrosion and weather.
Durapon 70 is one of Dura Coat’s new generation PVDF coatings designed to create an exceptionally tough surface that’s resistant to scratching, scuffing, transit abrasion and the elements, yet is flexible for the most demanding post-forming operations.
For added protection, Dura Coat now offers new Edge Seal, a clear, air dry sealer that is applied with a roller to help seal cut edges of metal panels and trim that occur during the installation process. Edge Seal can also be applied during routine roof maintenance.
Dura Coat Product’s Durapon 70 provides some of the finest metal protection available. With the addition of the new Edge Seal Coating, raw metal edges are also protected against corrosion.
