Sodium silicate, also known as waterglass, is a liquid chemical car dealer’s want, so their customers can get the newly approved $4500.00 CARS (Car Allowance Rebate System) government rebate.
On July 24th, 2009 the National Highway Safety Administration told US car dealers that they will be responsible for disabling the engines of automobiles traded in under the new “Cash for Clunkers” program.
The NHTSA’s Vehicle Research and Test Center (VRTC) specified a quick, inexpensive, and environmentally safe process to disable the engine of the trade-in vehicle while in the dealer’s possession. Removing the engine oil from the crankcase, replacing it with a 40 percent solution of sodium silicate and running the engine for a short period of time at low speeds renders the engine inoperable. Generally, this will require just two quarts of the sodium silicate solution.
The time involved should not substantially exceed that of a typical oil change. The agency has tested this method and found it safe, quick, and effective.
The agency considered several possible methods of rendering the engine inoperable and found this method was safe for workers involved, completely effective, environmentally sound, and relatively inexpensive for a dealer to use. NHTSA’s tested various methods and prepared a report summarizing the tests. VRTC evaluated four options: (1) the use of sodium silicate solution in the manner the agency has now adopted; (2) destroying the oil filter sealing land and threaded fastener boss; (3) drilling a hole in the engine block; and (4) running the engine without oil. VRTC concluded that the sodium silicate (waterglass)

The agency specified that the sodium silicate solution should be a 40% concentration and have a weight ratio of at least 3.0. Dealers should be certain the sodium silicate they use meets those specs.
