4 . Instruction and Attention:1) To reduce bubbles and achieve a broad gel time, use a low-activity curing agent like Butanox LPT by AKZO. When used as the outermost layer of pipelines and tanks, paraffin must be added to ensure proper curing.
When used as the outermost layer of pipelines and tanks, paraffin must be added to ensure proper curing. The recommended addition is 300ppm (melting point 52~57ºC). For optimal paraffin effectiveness, short gel time (approx. 30 minutes) is advised.
2) The recommended addition is 300ppm (melting point 52~57ºC). For optimal paraffin effectiveness, short gel time (approx. 30 minutes) is advised.
3)To reduce bubbles and achieve a broad gel time, use a low-activity curing agent like Butanox LPT by AKZO. When used as the outermost layer of pipelines and tanks, paraffin must be added to ensure proper curing. The recommended addition isactivity such as Butanox LPT produced by AKZO. When used as the outermost layer of pipelines and tanks, paraffin must be added to ensure proper curing. The recommended addition is300ppm (melting point 52~57ºC). For optimal paraffin effectiveness, short gel time (approx. 30 minutes) is advised.
5. Storage:
1) Store in a dry place below 25ºC, avoiding heat sources such as direct sunlight or steam pipes.
2) Keep containers sealed to prevent moisture and monomer loss. Prolonged storage outside recommended conditions may affect liquid resin properties like viscosity and gel time.
3) Transportation must comply with the State Council's 'Chemistry Dangerous Articles Safety Management Regulations.' Due to the styrene monomer content, the product is hazardous and flammable.
