Q Can Nanjing Qingqi Advanced Materials provide complete manufacturing technology and support for the production of MS sealants according to SMP specifications?
A As a raw material supplier, we are dedicated to providing comprehensive technical support for the production of MS sealants in full compliance with SMP specifications.
Q Can Nanjing Qingqi Advanced Materials offer technology for (1) Construction sealants, (2) Automotive sealants, and (3) Pouring-grade road sealants using MS chemistry?
A We offer proven technology for construction and automotive-grade sealants. For pouring-grade road sealants, further testing is necessary to tailor the solution to your specific requirements.
Q Can all grades of low, medium, and high modulus MS sealants be manufactured using a single blender?
A Yes, it is possible. We recommend a visit to our facility to explore our product line, followed by a tour of a reputable blender and packaging machine supplier in Jiangsu for detailed insights.
Q What type of heating system is required—steam, hot oil, etc.?
A Both steam and hot oil systems are viable, but hot oil is generally preferred for better control and efficiency.
Q Will the shelf life of the sealant be affected by air exposure during the transfer to the press and packaging? How can this be mitigated?
A Yes, air exposure can impact the shelf life. To mitigate this, we recommend introducing nitrogen into the mixer prior to transfer, along with using a plastic film barrier during the packaging process to minimize air contact.
Q What is the shelf life of the finished product under normal packing conditions and more stringent airless packaging conditions?
A Under standard packaging, the shelf life ranges from 6 to 18 months, depending on customer requirements. Utilizing more stringent airless packaging can further extend the shelf life beyond these ranges.
