2) Post curing: RT×24hrs +80ºC×24hrs;

4 . Instruction and attention:1) To minimize bubbles and achieve an optimal gel time range, use a low-activity curing agent like Butanox LPT from AKZO. When applying as an overcoat layer (such as the outermost layer of pipelines and tanks), paraffin must be added to ensure proper curing.
When used as overcoat layer (such an the outermost layer of pipeline and tank), paraffin must be added to ensure the expected curing degree.
2) The recommended addition is 300ppm (melting point 52~57ºC). Additionally, to maximize paraffin effectiveness, the resin should have a short gel time (approximately 30 minutes).
3)In order to reduce the bubble and achieve a broad gel time scale, curing agent with low activity such as Butanox LPT produced by AKZO. When used as overcoat layer (such an the outermost layer of pipeline and tank), paraffin must be added to ensure the expected curing degree. The recommended addition is 300ppm (melting point 52~57ºC). At the same time, to employ the paraffin to the best advantage, the resin should have a short gel time (approximately 30 minutes).
5. Storage:
1) Store away from heat sources such as direct sunlight or steam pipes. Keep in a dry place at temperatures below 25ºC.
2) Ensure the container is sealed to prevent moisture absorption and monomer loss. Extended storage outside recommended conditions can affect liquid resin properties like viscosity and gel time.
3) Transportation should comply with the State Council 'Chemistry Dangerous Articles Safety Management Regulations'. Due to its styrene monomer content, it is classified as hazardous and flammable.
