We are a certified manufacturer of construction sealant products for building and construction applications. Our construction sealants and adhesives include expansion joint sealers, butyl rubber sealers, butyl caulk, butyl tapes and beads. The rise in construction adhesive popularity has been due to its versatility and well-balanced properties. These sealants are suitable for a wide range of applications in the construction industry, such as on concrete construction joints, expansion joints of railways, airport runways, and highway/railway bridges, etc. and for building projects. Building & Construction Sealants Unique Properties Some of the unique properties of building sealants are: Solvent-free and environmentally friendly products. Low-temperature gunnability: the viscosity of deVan’s sealants is less dependent on temperature changes. Storage stability: shelf life is excellent although sealant must be protected from moisture. Weather resistance and durability: masonry sealant, wood sealant, and other construction sealants show no cracking, splitting, discoloration or adhesion failure after several years of testing. Stain resistance: construction adhesives do not stain as some sealants do because of low molecular weight, silicon materials that bleed from the surface of sealed joints. Adhesion: construction sealants provide adhesion to various substrates including metals, plastics, wood, and ceramics. Fast Curing Two-Component Sealants The two-component sealant products have the features of fast cure, high elongation and good elasticity. It is the most cost-effective waterproof polyurethane sealant currently offered. The single part sealant’s characteristics are its easy application, high solid content, high elongation, good water resistance, excellent durability, and fatigue resistance. These high-performance construction sealants will stick to almost any surface as they have a highly aggressive adhesion. Our sealants provide a perfect seal, which helps with achieving your construction specifications. We provide Safety Data Sheets to assure their material safety and quality. --- - Published: 2025-10-28 - Modified: 2026-03-10 - URL: https://www.devansealants.com/gasket-sealants/ - Categories: Caulk At deVan Sealants, we have the gasket sealant you need for automotive and other industrial or manufacturing production requirements. In automotive assembly, a head gasket sealant is used to seal the engine block and cylinder head in an automobile engine. A sealant is applied to both sides of the head gasket to ensure that the small surface irregularities in each mating surface are filled and that the two surfaces seal properly when joined together. Our gasket sealant products are ideal for automotive, truck and bus body applications or other requirements for leak-tight gasket seals. Pipe Gasket Sealant Applications The construction industry uses plumbing and utility piping applications that have flanges that form a joint. These connections are made using gasket sealants to ensure a leak-tight seal. Threaded piping connections also use a gasket sealant to prevent leakage through the very small clearance areas between the threads. These are just a few of the uses for gasket sealant materials. Custom, OEM & Standard Gasket Sealants Manufacturer If you need custom and OEM gasket sealer formulae to meet the necessities of commercial industry production, we have onsite capabilities to develop formulae and then produce the amounts that your company requires. We can also use your company formulations to duplicate a formula to your exact specifications. We also have standard formulations, bulk orders and lot productions of our commercial and industrial sealant products packaged and ready for delivery directly to your company. All our formulations meet or exceed federal, state, and local laws and ordinances regulatory requirements. Our quality products do not contain asbestos or related compounds and are guaranteed to be safe. We take safety and quality control seriously; and we use industry-best practices in production, storage, and shipment of our high-temperature gasket sealant. We provide all necessary and important safety guideline information for use and storage of our products to our B2B customers.

The goal of HVAC design is to balance indoor environmental comfort with other factors such as installation cost, ease of maintenance, and energy efficiency. The HVAC industry had been historically regulated by the manufacturers of HVAC equipment, but Regulating and Standards organizations such as HARDI, ASHRAE, SMACNA, ACCA, Uniform Mechanical Code, International Mechanical Code, and AMCA have been established to support the industry and encourage high standards and achievement. Industrial HVAC systems are particularly important in the design of medium to large industrial & office buildings such as manufacturing plants & skyscrapers where safe, healthy building conditions are regulated with temperature and humidity, as well as “fresh air” from outdoors. And at some time, these buildings & industries will need to have their HVAC systems maintained or repaired. DeVan Sealants provides HVAC sealants for repairs & refrigeration sealants for manufacturing.

Stopping refrigerant leaks by using a refrigeration sealant is not only profitable to a manufacturer’s bottom line, but it also saves energy and protects the environment from leaked refrigerants. Tips for Using an Industrial Refrigeration Systems Sealant for Repair The system should leak no more than 14 percent of its charge over a four-week period in order for a sealant to be used. Leaks this size and larger can typically be found by using standard electronic and dye detection methods. However, if the leak is undetectable or inaccessible, an industrial-strength sealant can be successful with leaks of this magnitude or smaller. Moisture, acid and any other non-condensable liquids must be removed from the system prior to administering the sealant. Systems that have leaked over 17 percent of their total charge are probably contaminated. Refrigerant recovery is recommended for the purpose of drying, removing light particulates, and replacing suction and liquid line dryers (where required). Then the refrigerant can be reintroduced back into the system if deemed suitable by the technician. Systems under five tons should not exceed an application of one three-ounce can of sealant. Systems over five tons can receive two cans, but separated by a minimum 10-day period. During this intermediate time, system pressure and temperatures should be checked to evaluate the first application’s success before adding the second can. Refrigeration Equipment Sealant Formulations Refrigeration equipment sealants are engineered for refrigeration leaks that go undetected because of their small size and/or intermittent nature. If you can find the leak, fix it. If you cannot find it, then use a sealant for refrigeration equipment. All sealants manufactured at deVan Sealants are non-hazardous and non-toxic under normal temperatures and storage conditions. We use industry-regulated practices in production, storage, and shipment; and we provide MSDS Sheets and Technical Sheets for all our products. At deVan Sealants, we offer the finest sealants and other industrial products available that you can rely on for commercial HVAC and refrigeration assembly and repair. --- - Published: 2025-10-28 - Modified: 2026-03-10 - URL: https://www.devansealants.com/refrigeration-sealants/ - Categories: Caulk We have the perfect high-performance industrial-grade refrigeration sealant products needed and used by your industry.

Due to its crosslinked butyl memory, it will pull back to size if stretched during processing. Description 589 is a sealant compound designed for use in window and door manufacturing. Due to its crosslinked butyl memory, it will pull back to size if stretched during processing. 589 is soft, resilient, pliable and easily worked by hand; yet adheres instantly to most commercial surfaces including PVC, polyethylene, polyester, glass, aluminum and wood. Because of its excellent adhesion to most materials, high resistance to chemical attack, resiliency, creep resistance and clean working properties, 589 may be used in almost any sealing application including: In window manufacturing where a re-extrudable sealant is desired for extruding to size or robotic sealant injection is needed in automated sealant operations. Window and door back bedding applications where cutting and removal of excess material is important. Sealing windows, panels and mullions in curtain wall and commercial building construction. Sealing of shower doors and joints between metal frame and tile walls. Wherever a freeze thaw material is required in refrigeration applications. Sealing metal lap joints. 589 is formulated to yield 100% cohesive failure in both wet and dry conditions. It is chemically inert, non-corrosive to paint, metals and plastic. It will not swell rubber. 589 will not flow, sag or pump from joint due to thermal expansion and contraction. 589. 12 is available in rope form on spools for re-extruding to size on manufacturing lines. Both 589. 12 and 589. 2 are available in convenient, ready-to-use tape or bead form in rolls or cut-to-length flat packs. 589. 12 and 589. 2 are also available as die-cut parts made to customer specification. Application Surfaces to which 589. 12 is to be applied need not be completely clean. In most instances, the aggressive adhesion of 589. 12 will accumulate over time. Any excess squeeze-out occurring during processing can easily be cut-off with minimum elongation or stretching. Customer testing is recommended to ensure the suitability for each application. Sealant squeeze out is a major concern when large lites are used. Lites greater than 100 united inches (length in inches plus width) require a continuous shim or rod in the center of the tape. The shim serves as a spacer to keep the glass from contacting the rabbit during periods of deflection. The rabbit surface must be serrated or other effective measures found, to retain the shim during thermal expansion and contraction. Regulations & Specifications FDA Regulation Meets U. S.
