Standards, causes and hazards of residual monomers in acrylic emulsions

Standard for residual monomers in acrylic emulsions
**The standard for residual monomers in acrylic emulsions usually does not exceed 0.5%**.

Causes of residual monomers in acrylic emulsions
The cause of residual monomers in acrylic emulsions may be due to improper operations during the production process or raw material quality issues. During the production process, if the reaction temperature, reaction time, catalyst and other conditions are not properly controlled, monomer residue may occur. In addition, if there are impurities or quality problems in the raw materials, monomer residues may also occur.

The dangers of residual monomers in acrylic emulsions
The hazards of residual monomers in acrylic emulsions mainly include the following aspects:
1. Impact on human health: Residual monomers in acrylic emulsion may cause irritation or allergic reactions to the human body, and long-term exposure may also cause damage to the respiratory system, eyes and other organs.

Impact on the environment: Residual monomers in acrylic emulsions due to improper operation or raw material quality issues. During the production process, if the reaction temperature, reaction time, catalyst and other conditions are not properly controlled, monomer residue may occur. In addition, if there are impurities or quality issues in the raw materials, monomer residues may also occur.

The hazards of residual monomers in acrylic emulsions mainly include the following aspects:

1. Impact on human health: Residual monomers in acrylic emulsion may cause irritation or allergic reactions to the human body, and long-term exposure may also cause damage to the respiratory system, eyes and other organs.
2. Impact on the environment: Residual monomers in acrylic emulsion may cause environmental pollution when discharged, causing adverse effects on aquatic organisms, soil, etc.
3. Impact on product quality: Residual monomers in acrylic emulsions may affect product performance and stability, leading to a decline in product quality.
Therefore, reaction conditions and raw material quality should be strictly controlled during the production process to ensure that the content of residual monomers in the product meets standard requirements.
