4 . Instructions and Attention:1) To minimize bubbles and achieve a consistent gel time scale, a low-activity curing agent like Butanox LPT by AKZO is recommended. For overcoat layers (like the outermost layer of pipelines and tanks), adding paraffin ensures the desired curing degree.
When applied as an overcoat layer, paraffin must be included to achieve the anticipated curing level.
2) The recommended addition is 300ppm (melting point 52~57ºC). For optimal paraffin utilization, the resin should have a short gel time (approximately 30 minutes).
3)To minimize bubbles and attain a wide gel time range, a low-activity curing agent like Butanox LPT by AKZO is preferable. When used as an overcoat layer for pipelines and tanks, incorporating paraffin is essential to ensure the desired curing level. The recommended addition is300ppm (melting point 52~57ºC). Additionally, to maximize the effectiveness of paraffin, the resin should have a brief gel time (about 30 minutes).300ppm (melting point 52~57ºC). Furthermore, to leverage paraffin's benefits, the resin should have a short gel time (approximately 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 avert moisture absorption and monomer loss. Extended storage under non-recommended conditions can affect liquid resin properties like viscosity and gel time.
3) Transport should comply with the State Council's 'Chemistry Dangerous Articles Safety Management Regulations'. Being styrene monomer-based, it is hazardous and flammable.
