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 bubbles and achieve a broad gel time scale, use a low-activity curing agent like Butanox LPT from AKZO. When used as an overcoat layer (such as the outermost layer of pipelines and tanks), paraffin must be added to ensure the desired curing degree.
When used as an overcoat layer (such as the outermost layer of pipelines and tanks), paraffin must be added to ensure the expected curing degree.
2) The recommended addition is 300ppm (melting point 52~57ºC). Additionally, to maximize the benefits of paraffin, ensure the resin has a short gel time (approximately 30 minutes).

5. Storage:
1) Avoid exposure 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 can 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'. Due to its styrene monomer content, it is classified as hazardous and flammable.
