Note:
1) The casting is formulated according to GB/T8237-2005; Curing System: Accelerator KC: 1.0%;
Hardener AKZO LPT: 1.0%;
2) Post curing: RT×24hrs +80ºC×24hrs;
4 . Instructions and Precautions:1) To minimize bubbles and achieve an extensive gel time range, use a low-activity curing agent like Butanox LPT from AKZO. When applied as an overcoat layer (e.g., the outermost layer of pipelines and tanks), paraffin must be added to attain the desired curing level.
2) The recommended paraffin addition is 300ppm (melting point 52~57ºC). To maximize the benefits of paraffin, the resin should have a short gel time (approximately 30 minutes).
2) The recommended addition is 300ppm (melting point 52~57ºC). To employ paraffin optimally, the resin should have a short gel time (about 30 minutes).
3)To minimize bubbles and achieve a broad gel time range, 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. The recommended addition is300ppm (melting point 52~57ºC). To employ paraffin optimally, the resin should have a short gel time (about 30 minutes).300ppm (melting point 52~57ºC). To maximize the benefits of paraffin, the resin should have 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 pick-up and monomer loss. Prolonged storage outside of recommended conditions can affect liquid resin properties like viscosity and gel time.
3) Transportation should comply with the State Council's 'Chemistry Dangerous Articles Safety Management Regulations.' As it contains styrene monomer, it is hazardous and flammable.
