Sodium Silicate 40% (Water Glass)

Works perfectly for bonding sand for hot metal casting inserts. This is exactly what the description says. There are less expensive options if you can sort out a company's efforts to hide simple ingredients under proprietary names or descriptions. At least with this you are sure what you are buying.

This holds like iron if you glue a rock to a 2x4 to run it through a slab saw. If you know what that means than you are looking at the right product.

I use some of this for the inside of my Forge works great, and stays in water to seal the head gasket as well make with cement in the insides are used sodium silicate

This replaces locktite red for semi-permanent thread locking where the parts are exposed to heat that would soften red thread sealer. The parts must be immersed in water for 24 hours before they can be separated with some difficulty. My application is for a muzzle break on the threaded barrel.

This worked for my 04 toyota 4 runner aluminum block and head. I tested this product with both green and red antifreeze in which it coagulated badly in a cup. To have success with this product you must drain all coolant from the motor. You need 16 ounces of product for a 4 cylinder, 24 ounces for a 6 cylinder and 32 ounces for a v6. It is imperative you drain the coolant. Do not add coolant until you drain the product. Drive it with only water and product for a couple months and you will have months of operation with no problem. Because my motor is aluminum head and block and freezing isnt a huge issue where I live Ive opted to just run the vehicle with water and product. I havnt had a problem one so far. Hope this helps. You do not need to bypass the radiator or heater core as this product only coagulates around the piston where you need it because of the very high temperatures. It will not coagulate anywhere else so you do not need to drain it unless you intend to add antifreeze. This product plus antifreeze equals a gelled mess you do not want in your motor.

I had never used this product before. I bought to install some high temp insulation on boiler tube doors(1500dgf). If it ever has to be removed they better have a grinder.

Still testing on wood. Works great as a box and label sealer.

perfect! & quick to ship
