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 scale, a low-activity curing agent like Butanox LPT from AKZO is recommended. When used as an overcoat layer (such as the outermost layer of pipelines and tanks), paraffin must be added to ensure optimal curing.
The recommended addition of paraffin is 300ppm (melting point 52~57ºC). To maximize the effectiveness of paraffin, the resin should have a short gel time (approximately 30 minutes).
2) The recommended addition is 300ppm(melting point 52~57ºC). At the same time, in order to employ the paraffin to the best advantage, the resin should have a short gel time (about 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, in order to employ the paraffin to the best advantage, 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 environment with temperatures below 25ºC.
2) Keep containers sealed to prevent moisture absorption and monomer loss. Prolonged storage outside recommended conditions can affect liquid resin properties like viscosity and gel time.
3) Transportation should adhere to the State Council's 'Chemistry Dangerous Articles Safety Management Regulations.' As the product contains styrene monomer, it is classified as hazardous and flammable.
