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 reduce bubbles and achieve a broad gel time scale, use a low-activity curing agent such as Butanox LPT by AKZO. When used as an overcoat layer (e.g., the outermost layer of pipelines and tanks), paraffin must be added to ensure the expected curing degree.
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 paraffin addition is 300ppm (melting point 52~57ºC). To maximize the effectiveness of the paraffin, 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 (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 the recommended conditions can affect liquid resin properties like viscosity and gel time.
3) Transportation must comply with the State Council's 'Chemistry Dangerous Articles Safety Management Regulations'. As it contains styrene monomer, it is hazardous and inflammable. Packaging & Shipping Application Certifications FAQ Q: Is Your Company a Manufacturer?
