4. Storage:
1) Avoid exposure to heat sources such as direct sunlight or steam pipes. Store in a dry place at temperatures not exceeding 25ºC.
2) Keep the container sealed to prevent moisture absorption and monomer loss. Prolonged storage outside recommended conditions can affect resin properties like viscosity and gel time.
3) Ensure transportation complies with the State Council's 'Chemistry Dangerous Articles Safety Management Regulations.' Due to the presence of styrene monomer, the product is classified as hazardous and inflammable.
