Hardener AKZO LPT: 1.0%;
2) Post curing: RT×24hrs +80ºC×24hrs;

4 . Instruction and attention:1) To minimize bubbles and achieve an extensive gel time range, use a low-activity curing agent such as AKZO's Butanox LPT. For overcoat layers (like the outermost pipeline and tank layers), add paraffin to ensure the desired curing level.
When used as an overcoat layer, paraffin must be added to ensure the expected curing degree.
2) The recommended paraffin addition is 300ppm (melting point 52~57ºC). To optimize its use, ensure the resin has a short gel time (approximately 30 minutes).
3)To minimize bubbles and achieve a broad gel time range, use a curing agent with low activity such as AKZO's Butanox LPT. For overcoat layers like pipelines and tanks, add paraffin to achieve the desired curing level. The recommended addition is 300ppm (melting point 52~57ºC). To achieve optimal results, ensure the resin has a short gel time (about 30 minutes).
5. Storage:
1) Avoid heat exposure such as direct sunlight or steam pipes. Store in a dry place below 25ºC.
2) Keep sealed to prevent moisture pick-up and monomer loss. Prolonged storage outside of recommended conditions can affect properties like viscosity and gel time.
3) Transportation should comply with the State Council's 'Chemical Dangerous Articles Safety Management Regulations'. Contains styrene monomer; hence, it is hazardous and inflammable.
