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 range, use a low-activity curing agent like AKZO's Butanox LPT. When used as an overcoat layer (such as on the outermost layer of pipelines and tanks), add paraffin to ensure proper curing.
When applied as an overcoat layer (such as on the outermost layer of pipelines and tanks), paraffin must be added to achieve the desired curing performance.
2) The recommended addition is 300ppm (melting point 52~57ºC). To maximize the effectiveness of the paraffin, the resin should have a short gel time (about 30 minutes).
3)To reduce bubbles and achieve a broad gel time range, use a low-activity curing agent like AKZO's Butanox LPT. As an overcoat layer (e.g., the outermost layer of pipeline and tank), adding paraffin is essential for the expected curing degree.activity such as Butanox LPT produced by AKZO. When used as an overcoat layer (such as on the outermost layer of pipelines and tanks), paraffin must be added to ensure proper curing. The recommended addition is 300ppm (melting point 52~57ºC). To utilize paraffin effectively, the resin should have a short gel time (about 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 impact liquid resin properties like viscosity and gel time.
3) Transport must comply with the State Council's 'Chemistry Dangerous Articles Safety Management Regulations'. As it contains styrene monomer, it is hazardous and flammable.
