4 . Instruction and Attention:1) To reduce bubbles and achieve a wide gel time range, use a low activity curing agent like Butanox LPT from AKZO. When applied as an overcoat layer (such as the outermost layer of pipelines and tanks), paraffin must be added to ensure the desired curing degree.
The recommended addition is 300ppm (melting point 52~57ºC). To maximize the benefits of paraffin, ensure the resin has a short gel time (approximately 30 minutes).

5. Storage:
1) Avoid exposing the resin to heat sources such as 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 may affect liquid resin properties like viscosity and gel time.
3) Transport should comply with the State Council's 'Chemistry Dangerous Articles Safety Management Regulations.' The resin contains styrene monomer, making it hazardous and flammable.
