| Epoxies |
Urethanes |
Our 100 series of 100% solids and water based epoxies and our 200 series of epoxy novalac products offer you the most complete range of epoxy systems available. From thin membranes to 1/4" trowel down materials, Duraguard epoxies offer excellent bonding capabilities, flexibility and durability. Surfaces are easy to install, resist many acids, alkalies and solvents and clean easily without the loss of hardness.
|
Our 300 series moisture cure and chemical resistant urethanes are cost effective, non yellowing and easy to apply. They are quick drying and provide the very best abrasion and chemical resistance. Duraguard 310 CRU is formulated to resist hydraulic fluids such as Skydrol 500B-4, making it ideal for hanger floors. Urethanes are easy to clean, flexible, provide crystal clear floors and the highest level of light reflectivity. |
| Methyl Methacrylates |
Vinyl Esters |
Our 400 series methyl methacrylate resurfacing systems are based on 100% solids, reactively cured methacrylate binder resins, pigments and inert silica or quartz fillers. They are quick drying, cure at temperatures as low as -20˚F, resist cracking, are USDA approved and highly resistant to acids and alkalies. Mehtyl methacrylates are best suited for chemical processing areas, food processing facilities, freezers and refrigerated warehouses. |
Our 500 series of high performance vinyl esters for concrete or steel are excellent coatings where superior solvent resistance is required. Vinyl esters enable areas to be returned to service quickly and provide protection from solvent spillage, fumes and immersion. Duraguard 520 may be spray applied to vertical surfaces. All products in the 500 series are suited to secondary containment areas, holding tanks and areas subjected to highly caustic fumes.
