Summary. You can use it, the white latex is very thick for a while, because the water vapor in it is differentiated, in this case, you can directly add boiling water to the inside, or you can directly add glue.
You can use it, the white latex is very thick between the limbs when you put it for a while, because the water vapor in the world is differentiated, in this case, you can directly add boiling water to the inside, or you can directly add glue.
White latex is one of the most widely used, largest and oldest water-soluble phonogram adhesives, which is a thermoplastic adhesive prepared by polymerization of vinyl acetate monomer under the action of initiator. It can be cured at room temperature, curing fast, high bonding strength, and the adhesive layer has good toughness and durability and is not easy to age.
After opening, it has been left for more than 3 years, can such white latex still be used?
It can be used ha. This shelf life is very long.

Hello, I am glad to serve you and give you the following answers: white latex is a commonly used adhesive, which is characterized by strong viscosity, good heat resistance, good aging resistance, good water resistance, good pollution resistance, and can be used for the bonding of various materials. However, if the temperature of white latex is below freezing, it will become very thick, which will affect its use.
The reason for the white latex: The adhesive of white latex is composed of polyurethane and water, and when the temperature is lower than zero, the water will freeze, making the polyurethane thick, thus affecting the use of white latex. Workaround:
1.The white latex is left at room temperature and waits for the temperature to rise to allow it to become soft and thus restore its use. 2.
Add a small amount of warm water to the white latex and stir well to make it soft and thus restore its use effect. 3.Add a small amount of warm oil to the white latex and stir well or tung to make it soft and thus restore its use effect.
Personal experience: White latex is a commonly used adhesive, but its temperature cannot be lower than zero, otherwise it will become very thick, affecting its use effect. Therefore, when using white latex, attention should be paid to the temperature control to ensure the use effect of rock evidence.

Milky gum is a water-soluble adhesive that is made of vinyl acetate.
The monomer is a thermoplastic adhesive prepared by polymerization reaction under the action of initiator. Commonly known as white latex.
Or abbreviated as PVAC emulsion, chemical name polyvinyl acetate adhesive, is made of acetic acid and ethylene to synthesize vinyl acetate, add titanium dioxide (low-grade add light calcium, tease and defeat talcum powder.
and other powders).The milky white thick liquid tremor formed by emulsion polymerization is a very versatile adhesive. The name is different in different places, and milky white rubber is also called white latex.
That's a very good question.
