Note:
1) The casting is made according to GB/T8237-2005; Curing System: Accelerator KC: 1.0%; Hardener AKZO LPT: 1.0%;
2) Post Curing: RT×24hrs +80ºC×24hrs;
4. Instruction and Attention:
1) To minimize bubble formation and achieve a broad gel time scale, use low-activity curing agents like Butanox LPT produced by AKZO. When used as an overcoat layer (such as the outermost layer of pipelines and tanks), paraffin must be added to ensure the expected curing degree.
When used as an overcoat layer (such an the outermost layer of pipeline and tank), paraffin must be added to ensure the expected curing degree.
2) The recommended paraffin addition is 300ppm (melting point 52~57ºC). For optimal paraffin effectiveness, the resin should have a short gel time of 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). For optimal paraffin effectiveness, the resin should have a short gel time of approximately 30 minutes.
5. Storage:
1) Keep away from heat sources like direct sunlight or steam pipes. Store 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 such as viscosity and gel time.
3) Transportation must comply with the State Council's "Chemistry Dangerous Articles Safety Management Regulations." Due to the presence of styrene monomer, this product is hazardous and flammable.
