Cold Weather Epoxy Storage. It will flow out much smoother and penetrate better, resulting in a stronger bond. Learn more about uses of WEST SYSTEM Epoxies in Epoxyworks magazine. CAUTION! Another temperature-related problem occurs throughout the year, even in warm climates, when overnight temperatures drop well below daytime temperatures. It’s much more difficult balancing all of the physical and mechanical properties necessary for a versatile, high-quality marine grade epoxy. In some cases, your shop will naturally warm itself enough to complete the cure during the day, following a cold night. Warmer temperatures accelerate the reaction, while cooler temperatures retard the reaction and reduce the cross-linking activity of the epoxy molecules.

Tim Hickey, president of CFC-Concrete Floor Coatings Inc. in Laguna Hills, Calif., has been installing the Pebble Bond Epoxy System from Life Paint for almost eight years. With a little planning and by observing the following eight precautions, most of these problems can be overcome and their consequences avoided. However, this doesnât mean that you can never use epoxy in cold weather. The potential for inaccurate metering and incomplete mixing, compounded by a less efficient chemical reaction, greatly increases the possibility of a deficient bond. All epoxy resin/hardener combinations go through the same phases of cure. For example, a can of soda can sit on a grocers shelf for a year and still tastes fine when opened. The time required depends on the hardener used, the post-cure temperature and how much further the cure has to go. Allow extra time for pre-stressed joints and joints that will be subject to high loads. The Hardener Selection Guide shows the ideal temperature range for each hardener. Florock is an industry-leading epoxy and resinous floor finishes manufacturer. If the temperature is too low, the epoxy may eventually harden, but may not reach a complete cure or achieve its designed physical properties. However, if concrete is mixed with epoxy, the patch is able to flex with the movement of the foundation. Epoxy resin that is subject to freeze/thaw cycles may crystallize. We are an employee-own, family run organization that has maintained our performance-driven development of marine epoxies since the company was founded in 1969 . Mix the resin and hardener longer than normal (two minutes minimum) and scrape the sides and bottom of the mixing container. Everything we find out in the lab is followed up by real-world experiences with epoxy. Place the open containers in a pan of hot water and stir the epoxy with a clean stick until all crystals have melted and the liquid becomes clear. 7. For some applications, either epoxy system will work. A concrete patch is good if the earth doesn't continue to move. When coating at cold temperatures, the slower cure can result in the formation of amine blush on the surface. However, simply using a hardener that cures in colder temperatures does not guarantee dependable bonds. 4. For example, many of the joints may be subject to millions of small, repeated (fatigue) loads. WEST SYSTEM Epoxies have always been developed, formulated, and manufactured in our Bay City, Michigan plant by epoxy users who are enthusiastic about epoxy quality and ease of use. WEST SYSTEM Six10 is a thickened Epoxy Adhesive combines the strength and reliability of a two-part WEST SYSTEM® Brand Epoxy with point-and-shoot convenience. Outdoors, building a plastic tent to trap solar heat can easily boost the temperature enough for post-cure even during cool weather. If the resin in the pump has crystallized, pumping warm resin through it should dissolve the crystals. Several resin/hardener combinations are required, each one formulated to perform best in a different range of application temperatures. CAUTION!âHeating a porous material may cause air within the material to expand and âout-gas.â If an epoxy coating applied over the material has not gelled enough before starting the post-cure, bubbles from the out-gassing material may show up in the cured coating. Weâve told you all of the reasons why cold-temperature bonding with epoxy can be difficult and risky. The self-metering coaxial cartridge dispenses a gap-filling structural epoxy that bonds tenaciously to wood, metals, fibreglass and concrete. 205 Fast Hardener cures at much lower temperatures but has a very short working time at higher temperatures. Water vapor can condense on the cooler surface and affect the adhesion and cure of epoxy applied over it. Ambient temperature has a profound effect on the working or handling properties of uncured epoxy as well as its rate and degree of cure. Information about fatigue, fatigue testing, and how flexibility affects the fatigue life of epoxy, can be found in Fatigue Aspects of Epoxy and Wood/Epoxy Composite MaterialsÂ (pdf). 209 Extra Slow Hardener will not cure properly at low temperatures but provides more working time at higher temperatures. 205 Hardener has been designed with a polyamine system that cures well at temperatures as low as 35Â°F (Figure 2). Epoxy resin flooring, concrete coatings, and polished cement systems all provide years of lasting durability and beauty inside any room. Dispense epoxy resin and hardener in the proper mixing ratio only. A number of other factors can significantly affect your epoxyâs bonding ability in cold weather. The daily variation in temperature may cause moisture contamination problems if epoxy is applied to an exposed structure or surface too early in the day. Hire West Palm Epoxy Floors and save. Defining an epoxy’s performance criteria and designing a formula to meet those criteria require good chemistry, rigorous test programs, skillful shop work, and direct experience with high-performance boats and other composite structures. For a given volume of resin and hardener, a smaller diameter mixing pot will improve the chemical activity because the limited surface area will not dissipate heat produced by the chemical reaction. However, the formation of crystals does not permanently harm the epoxy, and they can be removed easily. He offers the service alongside other epoxy systems and concrete polishing. If you are not able to warm the resin and hardener, do not use excessive force when dispensing. The surrounding or ambient temperature affects the mixtureâs temperature and its rate of reaction and degree of cure. Although any temperature elevation will improve cross-linking, try to boost the temperature to room temperature (72Â°F) or warmer. However, the formation of crystals does not permanently harm the epoxy, and they can be removed easily. From your garage to your master bathroom, we can help enhance and protect any living space. Although epoxies can be formulated to cure in a wide range of working conditions, no one resin/hardener combination is ideal for all conditions. Before the water evaporates, dry the surface with plain white paper towels and sand any remaining glossy areas with medium-grit sandpaper. Remove from the water, replace the lids tightly and invert the container to melt any crystals which may be clinging to the top of the container. West System 105A Epoxy Resin (32 fl oz) Bundle with 207SA Special Clear Epoxy Hardener (10.6 fl oz) and 300 Mini Pumps Epoxy Metering 3-Pack Pump … Warm the epoxy bonding surface as much as possible. Do not exceed 140Â°F and do not remove clamps or load the joint until after the final cure. WEST SYSTEM epoxy’s adhesion to concrete is excellent. In bonding applications, the thicker epoxy will not wet out or penetrate porous surfaces as well and may result in an unreliable bond. Based in Windermere we work all over the North West, including Manchester and Cheshire. Epoxy brands vary widely in their formulations, quality of raw materials, and suitability for marine environments. In addition, air bubbles show through clear coating applications. Tents of plastic or insulated board are very helpful for confining the heat to specific areas and provide greater mobility with a limited heat source, both indoors and outdoors. It provides a strong, stable interface between the base material and other coatings or other materials bonded with epoxy. Epoxy can be used at cold temperatures but must be handled and applied with techniques adapted to cold temperatures. 2. WEST System Epoxy combined with additives can be used for filling and fairing holes and voids. Keep in mind the extended cure time required before removing clamps or sanding. Post-curing can help to complete the epoxy mixtureâs cross-linking and boost the epoxyâs physical properties even after a week or two of cold temperatures. Mixing an epoxy resin and hardener together starts a chemical reaction that produces heat. Developed specifically for boat building, boat repairs and the marine industry, and internationally marketed for 50 years, WEST SYSTEM epoxy is a versatile, high-quality, system that is easily modified for a wide range of coating and adhesive applications. Shelf life commences when a material is made. Epoxy resin that is subject to freeze/thaw cycles may crystallize. It is best to store WEST SYSTEM epoxy resin and hardeners above 35Â°F with the container caps screwed down tightly to avoid moisture contamination. First, it is more difficult to meter and mix the resin and hardener. They rely on a complex chemical reaction to achieve their strength and longevity. Prepare surfaces carefully between epoxy applications. Two-part strength in caulking gun convenience. 2 Basicbarriercoating WEST SYSTEM epoxy is a structural coating. We know that most epoxies perform well or, at least reach a higher percentage of their potential physical properties, at temperatures of 60Â°F and above.
