Note:
1) The casting is made according to GB/T8237-2005; Curing System: Accelerator KC: 1.0%;
Hardener AKZO LPT: 1.0%;
2) Post curing: RT×24hrs + 80ºC×24hrs;

4 . Instruction and Attention:1) To minimize bubble formation and achieve a broad gel time, use a low-activity curing agent like Butanox LPT from AKZO.
When used as an overcoat layer (outermost layer of pipeline and tank), paraffin must be added to ensure proper curing.
2) Recommended addition: 300ppm (melting point 52~57ºC). To maximize paraffin effectiveness, ensure the resin has a short gel time (approx. 30 minutes).

To maximize paraffin effectiveness, ensure the resin has a short gel time (approx. 30 minutes).
5. Storage:
1) Store in a dry place below 25ºC, away from heat sources like direct sunlight or steam pipes.
2) Keep sealed to prevent moisture absorption and monomer loss. Extended storage outside recommended conditions may affect resin properties like viscosity and gel time.
3) Adhere to State Council's 'Chemistry Dangerous Articles Safety Management Regulations' during transportation. It contains hazardous and inflammable styrene monomer.
