Urban Heat Islands and Cooler Infrastructure: An Experimental High-Albedo Roof Coating Study
Presenter: Thomas J. Taylor, PHD, Executive Director Building Science, GAF
A thirteen year old granulated modified bitumen roof was coated in six equal areas during September and October 2013. Each section had a due East-West orientation and received applications from different reflective roof liquid coatings, following each suppliers installation guidelines. Total roof area was approximately 20,000 square feet with an unobstructed exposure to the atmosphere. The coatings conformed to product specifications for initial solar reflectance (SR) which was measured at the time of installation. After two years of aging without surface cleaning, SR, visual and temperature data were collected. The temperature data was obtained using a FLIR thermal imaging camera during four site visits from July to October 2015. Results show that after two years of aging significant differences existed between the coatings in terms of both visual observations and measured performance. Thermal data amply confirmed and correlated with the visual observations and the aged SR changes and were consistent among the four sites visits, each of which was conducted during calm, clear, sunny weather conditions. After four years of aging, samples were taken from each section of the roof. These were evaluated for solar reflectance as well as a range of other properties. Differences were found again between the coatings. The study confirms the ability of coatings to lower roof top temperatures but shows that significant performance differences exist between the types of coatings.
Coating Transparency: Environmental Product Declarations and Harvested Rainwater Quality
Presenter: Jason Carlson, Staff Chemist, UL LLC
Co- Presenter: Josh Jacobs, Technical Information & Public Affairs Manager, UL LLC
If a customer asked you today; How have you backed up your environmental claims and product declarations? or Is it safe to use your companies' coating for rainwater harvesting? What would you tell them? If you are not sure how to answer these questions or are not familiar with Environmental Product Declarations (EPDs) or NSF Protocol P151, this session is for you.
Exploring Primers for Silicon
Presenter: Hans Haas, Technical Service Director, AB Specialty Silicones
Generally, poor wet adhesion is achieved on TPO membrane unless a primer is used. Chlorinated polyolefin primers have been shown to produce good wet and dry peel adhesion when used on TPO membrane in conjunction with silicone roof coating. This paper will explore the actives concentration needed in solvent-based chlorinated polyolefin primers to achieve good peel adhesion over TPO membrane with silicone roof coatings to determine the upper and lower limit on actives content in VOC-exempt solvent. Results of water-based chlorinated polyolefin primer compositions on TPO will also be presented and discussed.
Formulating Roof Coatings for Adhesion and Asphalt Bleed-through Resistance
Presenter: Brent Crenshaw, Scientist, EPS Materials
The choice of raw materials in a roof coating formulation solvent, binder, filler, pigment, surfactants, rheology modifiers, etc. and their quantities can have a dramatic effect on the final properties of a roof coating. This presentation will provide an overview of the different formulation components and what effect they have on film properties such as tensile strength, elongation, adhesion, water resistance, flexibility and asphalt bleed-through resistance. Test data will be analyzed and presented to demonstrate correlations. Particular emphasis will be placed on the effect of formulation parameters on adhesion and asphalt bleed-through resistance.

Effects of Silane Modification of Styrene Acrylic Polymers for Construction Applications
Presenter: Tamer Tezel, Technical Solutions Manager, Organik Kimya
Non-cementitious waterproofing materials are being more and more common due to ease of application in construction industry. Because of the challenging requirements such as crack bridging ability, water resistance, flexibility and dirt-pick up resistance, monomer compositions leading to softer polymers are generally preferred in formulating dispersion based waterproofing products. However, most of the time, some special additives (such as silanes, x-linkers etc..) are needed as post additives in final formulations to modify/improve those features. In this study, mechanical performance and water resistance of polymers with different monomer compositions have been compared not just as polymer films but also in a polymer loaded high performance dispersion based water proofing membrane formulation. The aim of the study is to demonstrate the additional benefits brought by the silane modification to the styrene acrylic polymers and to observe its impact on mechanical properties, recovery, flexibility, adhesion and water resistance.
Dirt Pickup Resistance: The Influence of Testing Parameters and Formulation Variables on Performance
Presenter: Joseph Rokowski, Technical Director, Insulating Coatings Corporation/Astec Re-Ply
Dirt resistance has been a key property of highly elongative, highly exterior durable roof coatings for many years, encouraging the development of numerous test methods. Many accelerated lab tests which exist to predict long term exterior dirt pickup performance do not discuss the factors which influence the lab tests results. This work will disclose some of the variables, such as drying conditions, synthetic 'dirt' differences and formulation variables which can provide atypical accelerated dirt pickup results. The information will provide guidelines for running more reliable dirt pickup resistance test methods.

Establishing ASTM D7281 "Standard Test Method for Determining Water Migration Through Roof Membranes as Appropriate for Roof Coatings
Presenters: Ed Buczek, Senior Product Manager, Henry Company; Thomas Tepe, PHD, Global R&D Director, Henry Company
A desirable property of a roof coating is its ability to resist water migration or "leaking". Without an industry-wide accepted test method to quantify waterproofing of a roof coating film, this presentation addresses how and why ASTM D7281 "Standard Test Method for Determining Water Migration Through Roof Membranes" could be applicable to roof coatings and be established as a standard industrial definition of "waterproof". The test procedures demonstrated in the lab and the factors that influence the test will be reviewed in detail. The film properties like thickness and mechanical properties that are relevant to the test will be discussed. Several types of roof coatings were tested according to this method to demonstrate that this ASTM standard is indeed applicable to roof coatings as it is to conventional roof membranes.
Waterborne Roof Coatings Meeting European Waterproofing Standards
Presenter: Jouko Vyorykka, PHD, Research Scientist, Dow Europe Gmbh
This presentation discusses the certification process of liquid applied roof waterproofing coating product category with focus on technical requirements and tests associated when assessing the durability and fitness for use. In Europe the dominating chemistry in the liquid applied roof waterproofing market is polyurethane based, and often it is delivered as a solvent borne system. In this presentation we introduce a newly developed waterborne acrylic polyurethane polymer for roof waterproofing applications that passes European norms and can therefore reach CE marking. The benefits of this new polymer system are also described in terms of sustainability and health and safety.
Accelerating Film Formation of Acrylic Roof Coatings
Most water-based, acrylic roof coatings require a lengthy cure time, and thus are vulnerable to wash-offs from early rainfall soon after application. Acrylic roof coatings are typically applied in multiple layers requiring lengthy application times, and high labor costs. Lack of early rain resistance impacts timely application, results in costly repairs, and negatively impacts the properties of the coating. This paper highlights the approaches to accelerating film formation in acrylic roof coatings, describes various conditions impacting film formation, and outlines a method for evaluating the early rain resistance of roof coatings.
