Urethane Systems and Thin Build

High-Build systems are popular in high-traffic areas due to their compressive strength and impact resistance. These systems typically have 2 varieties with a build of approximately 20-30 mils : Two typical Systems 1. Thin coat of epoxy primer followed by a thick coat of epoxy topcoat. 2. Thin coat of epoxy primer followed by a thick coat of epoxy intermediate coat, with a thin topcoat of urethane. For shot blasted or scarified surfaces, a high-build epoxy primer (AD0LVP) may be used as a substitute for a thin epoxy primer suck as AD134. If the substrate is very porous, it may be necessary to prime first with AD134 or AD5 before using AD0LVP
Primers Primers used in thin-mil systems work the same for high build applications. The primer coat is to maximize adhesion and help prevent air bubbles. AD5 is a water-based epoxy with a mixed VOC of 1.01 pounds per gallon, and emits no offensive odors. It is an ideal primer for a thin-mil system where VOC is an issue. AD134 is a solvent-based epoxy primer that is a cost-effective, high-quality primer for a system where VOC is not an issue. AD144 is the clear version of this product. Most popular primer and often used for a cost effective thin build system. Two coats of AD134 then top coated with AD311. AD0LVP is designed for use in situations where more than a typical 3-4 mils is needed for a primer coat. This product is a 93% solids epoxy, and can be applied at 6-12 mils. Ideal primer for shot blasted/BlasTrac floors. AD0LVP is NOT UV-color stable, and we strongly recommend top coating this product with a pigmented urethane Intermediate/Build or Stand-Alone Coat (AD77 for a one coat high build coating - very high performing.) AD77 is one of our best-selling products – a 100% solids epoxy build coats. This product has excellent compressive strength and impact resistance. AD77 can be top coated with AD311 for additional color stability & chemical resistance. AD100 is a 100% solids epoxy intermediate coat designed to be used in situations where the floor is going to be top coated with a color-coordinated urethane. This product will discolor under UV light if not top coated. AD100’s upside is the cost differential in comparison to other 100% solids epoxies that are more UV-resistant. AD0HV - Used if no topcoat being used. This product is similar to AD77 but formulated specifically for a single color no topcoat floor. Top Coats-Epoxy and Urethane Clear Epoxy Topcoat - For a heavy smooth finish. AD127MUV is our best-selling UV stable 100% solids clear epoxy. AD127MUV exhibits excellent wear characteristics, clarity, ease of use, and UV stability is the benchmark UV rating in the industry. (New formula in 2007) This product can be top coated with AD311 to maximize UV resistance and wear. - (This is the recommended top coat system for a high build floor.) AD311 is a top-of-the-line, solvent-based, two-component, aliphatic urethane topcoat. This product exhibits excellent UV stability, abrasion resistance, chemical resistance, and flexibility. AD311 can be used in many facilities, including warehouses, manufacturing facilities, aircraft hangars, auto service centers, and much more. AD348 High Performance Urethane is a three component aliphatic urethane floor finish that exhibits excellent characteristics for abrasion resistance, chemical resistance, flexibility, weathering and UV stability. Recommended for auto service centers, warehouses, computer rooms, laboratories, aircraft hangers, cafeterias, indoor or outdoor service and chemical exposure areas. This product must go on at recommended thickness to prevent fish eyes. AD339 - AD339 is a two component 100% solids polyaspartic aliphatic urethane seamless binder for broadcast systems. This material can be used with dried colored sand mixtures to provide an infinite array of color schemes or patterns. AD339 has excellent chemical resistance, hardness, abrasion resistance, UV stability and has an excellent clear gardner color. However, the outstanding feature of this product is its exceptionally quick tack free time of around 1-2 hours for foot traffic while providing the applicator about a 15-20 min. pot life to work with the material. AD20 is a water-based aliphatic urethane topcoat designed to provide excellent abrasion resistance without the typical odors associated with an aliphatic urethane. This product also has an extremely long pot life, and a lightning-fast cure time. At 70 degrees F, the floor can generally be opened to foot traffic in 3-4 hours. AD20 is not recommended for heavy traffic areas.
