4 . Instruction and Attention:1) To minimize bubble formation and achieve a broad gel time range, use a low-activity curing agent like Butanox LPT by AKZO.
For overcoat layers (e.g., the outermost layer of pipelines and tanks), add paraffin to ensure optimal curing.
2) Recommended paraffin addition is 300ppm (melting point 52~57ºC). For best results, the resin should have a short gel time (approximately 30 minutes).

5. Storage:
1) Avoid exposure to heat sources like direct sunlight or steam pipes. Store in a dry place at temperatures below 25ºC.
2) Keep sealed to prevent moisture absorption and monomer loss. Prolonged storage outside recommended conditions can affect properties like viscosity and gel time.
3) Follow the State Council's 'Chemistry Dangerous Articles Safety Management Regulations' for transportation. Contains styrene monomer, making it hazardous and flammable.
