Big Dog Adhesives specializes in Methyl Methacrylate Adhesives (MMA), exclusively manufactured at our facility in Elkhart, Indiana. With a deep expertise in this adhesive technology, we deliver reliable and robust products to meet our customers’ needs. Our portfolio includes a diverse range of MMAs tailored for various applications: from long working time formulations ideal for boating (BD560, BD590), to quick-setting adhesives for general bonds (BD300, BD310, BD330), and specialized variants such as Low Exotherm, UV Stable, and Impact Modifiers. We prioritize MMA adhesives for their exceptional properties, including no surface preparation requirement, versatility in bonding substrates (Steel, Aluminum, Plastics, Fiberglass), and the capability to incorporate diverse additives for custom formulations.

PROUDLY MADE in the USA in Elkhart, Indiana, the Hoosier State, with employees like you, we go the extra mile to make it right and get it to you quickly! Unlike other newer manufacturers who haven’t figured out what they don’t know, SeamLock isn’t runny or too thin, or inconsistent, or made with who knows what.

Super Glues (Cyanoacrylates adhesives – CA) is the general term for very quick bonding adhesives that bond substrates together in a very quick reaction. Super glues bond all sorts of various substrates together, such as wood, plastics, metals, rubbers and a variety of other substances. In general, most of the super glues are single component adhesives, generally clear or slightly cloudy in nature, that are easy to use, fast curing with rapid fixture time. Effectively, they work in the presence of moisture (water), meaning moisture in the air. Most of us have used super glues and have glued our fingers together, probably by accident, because the skin has a high degree of moisture. Often, specialized super glues are used to close up wounds, or seal cuts and scratches. Big Dog also makes an accelerator, and can speed up these super glues so they react even faster.  Big Dog supplies them in 4 different thickness, Thin, Medium, Thick, and Gel to suit every need.

Epoxy Adhesives

Welcome to Big Dog Adhesives, a renowned manufacturer specializing in Epoxy Adhesives, renowned for delivering superior strength and durability to our valued customers. Our comprehensive range includes products with varying working times, from rapid-curing options like BD5405 and BD5410, to long set formulations such as BD5430 and BD5460, accommodating diverse application needs. 

Our epoxy adhesives are engineered to offer exceptional resistance to water, salt spray, inorganic acids, bases, and most organic solvents. They are ideally suited for industrial bonding, small potting, and laminating applications where robust strength, toughness, and superior mechanical and electrical properties are essential.


Aerobic means in the presence of air (specifically, oxygen). Anaerobic means without the presence of air ( again, oxygen). So, anaerobic adhesives cure in spaces that do not have oxygen (air). The other requirement is that there must be metal present, or one of the spaces must be in contact with metal. Therefore, anaerobic adhesives are used in places that have no air, and have metals around them. A good application for anaerobic adhesives ( or threadlockers), is in the area of turning a nut into a bolt. The anaerobic adhesive fills the gap between the nut and the bolt, thereby having metal on both sides, and without the presence of air. The adhesive then reacts rather quickly, and the nut is sealed or prevented from working it way tighter, or working itself looser. Sometimes, anaerobics are applied to the bolts or the nuts separately, and shipped as such, so that when the nut is threaded to the bolt, the reactions occurs. In the past years, nylon nuts or nylon inserts used to do this, but in today’s modern world, anaerobic adhesives are replacing nylon nuts due to its stronger holding potential, lower cost, and ease of use.


Big Dog’s polyurethane adhesives are used for bonding many dissimilar materials together, such as ceramics and glass, plastics, rubbers, wood products an, having good metals. Big Dog’s adhesives are flexible, low VOC (contain low Volatile Organic Components), and are easy to use. Depending upon your design criteria, we can design a polyurethane that is UV stable, optically clear, flexible, having good strength and impact resistance.


Big Dog’s Flex-Lok adhesives are two-part epoxy modified siloxane polymers (MS Polymers) that have a wide range of use for bonding various substrates. The Flex-Lok product line has extremely flexible properties, maintaining that flexibility at a wide range of temperatures, from -70°F to 350°F (-60°C to 177°C). Supplied in easily dispensed 1 to 1 side by side cartridges, and in bulk, 5-gallon pails, and 55-gallon drums. Flex-Lok adhesives bond fiberglass, ceramics, concrete, wood, particle board, MDF, steel, aluminum and various plastics without the need of a primer. Flex-Lok adhesives will not bond low energy surfaces, such as polyethylene, polypropylene, Teflon, and other low energy surfaces. Flex-Lok adhesives outperform most brittle two component systems by retaining high peel strength and flexibility through a wide range of temperatures.
