4 . Instruction and attention:1) To minimize bubbles and achieve a wide gel time range, use a low-activity curing agent such as Butanox LPT by AKZO.
When used as an overcoat layer (e.g., outermost layer of pipelines and tanks), add paraffin to ensure the desired curing degree.
2) Recommended paraffin addition is 300ppm (melting point 52~57ºC). Moreover, to optimize the paraffin usage, ensure the resin has 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. Extended storage outside recommended conditions may affect liquid resin properties such as viscosity and gel time.
3) Transportation should comply with the State Council's 'Chemistry Dangerous Articles Safety Management Regulations.' As it contains styrene monomer, it is hazardous and flammable.
