2) Post curing: RT×24hrs +80ºC×24hrs;

4 . Instruction and Attention:1) To minimize bubble formation and extend the gel time, utilize a low-activity curing agent such as Butanox LPT produced by AKZO. When used as an overcoat layer (e.g., the outermost layer of pipelines and tanks), paraffin must be added to ensure optimal curing.
For overcoat applications, add paraffin to achieve the desired curing degree.
2) Recommended addition is 300ppm (melting point 52~57ºC). To maximize the efficacy of paraffin, ensure the resin has a short gel time (approximately 30 minutes).
3)To minimize bubbles and achieve a broad gel time scale, use a low-activity curing agent like Butanox LPT from AKZO. For overcoat layers,such as the outermost layer of pipelines and tanks, paraffin must be added to ensure the expected curing degree.Recommended addition is 300ppm (melting point 52~57ºC). Ensure the resin has a short gel time (about 30 minutes) to maximize paraffin's efficiency.
5. Storage:
1) Store in a dry place at temperatures below 25ºC. Avoid exposure to heat sources such as direct sunlight or steam pipes.
2) Keep sealed to prevent moisture pick-up and monomer loss. Prolonged storage outside recommended conditions may affect liquid resin properties like viscosity and gel time.
3) Transportation must comply with the State Council's 'Chemistry Dangerous Articles Safety Management Regulations.' Due to the styrene monomer content, the resin is hazardous and flammable.
