Comparative study completed on EnviroLoc 180C™ versus Traditional Liner such as High Density Polyethylene (HDPE).
EnviroLoc 180C™ Environmental Containment Systems
EnviroLoc 180C™ is composed of 100% solids, two component spray systems which have extremely fast reactivities and cure times. This technology is similar to high-performance polyurethane systems currently used, except for several key points. In EnviroLoc 180C™, JEFFAMINE® polyoxyalkylene diamines and triamines have replaced the polyols, amine chain extenders are utilized, and catalysts have been eliminated.
Spray systems based on this technology are good candidates for both coating and noncoating-type applications. In either application case, the chemical resistance of the coating material could be of major importance.
These charts describe the chemical resistance of selected systems. The systems utilized are standard systems, including both aromatic and aliphatic. It is believed that these systems give a good representation of each particular type of technology. For testing purposes, both ASTM D 1308 and ASTM D 3912 methods were utilized. These tests were performed at 24°C/75°F with visual observations being noted at the end of the test procedures. These test results are reported to serve as a guide in a variety of applications.
It is the responsibility of each EnviroLoc 180C™ supplier and or end user to assess suitability for specific applications.
ASTM 1308: Effect of Household Chemicals on Clear and Pigmented Organic Finishes.
This test describes the "spot test" or "watch glass" method to stimulate exposure of the coating through possible spillage. Each chemical was in contact with EnviroLoc 180C™ for a period of seven days, except where noted. Visual observations were made on EnviroLoc 180C™ daily and additional chemical was added as needed. The tested area was covered with a watch glass to inhibit evaporation and or contamination of the chemicals. Chemicals used as well as results can be found in Table 1.

ASTM D 3912: Chemical Resistance of Coating Used in Light-Water Nuclear Power Plants
This method describes the immersion method of exposure for a coating system to chemicals. In this testing procedure, a black pigmented aromatic was spray-applied to 2 mil blast profile steel panels, giving total encapsulation. These coated panels were then immersed halfway into individual chemicals for a period of 1 year at 25°C/77°F, except where noted. The panels were then removed and inspected. Chemicals used as well as results can be found in Table 2.
