Water-based inorganic coatings are mainly composed of silicate and water-soluble silica sol, and latex paints are organic coating film-forming substances and are petrochemical products Mainly, it can be identified in a simple way.  

 1. Open the can and smell the texture
1. Open the lid of the paint bucket, and stir the paint until evenly
2. Smell whether there is a pungent smell. The pungent smell, especially the smell of inferior latex paint. This smell is mainly composed of organic volatile formaldehyde and other harmful substances.  
3. Use a roller to brush the paint on the wall to see if there are tiny grains. Water-based inorganic paints are generally made of minerals, so they have graininess. The surface of latex paint is relatively smooth and shiny.

2. Burn the coating film to see the flame and smell

1 . Open the lid of the paint bucket and stir the paint until evenly
2. Apply the paint evenly on the film, dry it in a 40—60°C oven or dry it naturally
3. Peel off the paint coating from the film, use tweezers to pick up a small piece of coating, and use an alcohol blowtorch or a windproof lighter to ignite the coating in a ventilated place.
Inorganic coatings can withstand high temperatures of 1200 ° C, do not burn, and do not produce irritating gases. Even if they burn red, the coating will be extinguished immediately after leaving the flame. Latex paint can burn and be ignited within a few seconds , It can burn by itself after leaving the flame, and produce harmful gas with strong pungent smell. It will be very uncomfortable for the human body to breathe.
