Recently, an innovative cross-linked liquid sulfonated siloxane product named SI-S-L003 has officially entered the market. With its core advantages such as controllable cross-linking rate and excellent mechanical balance, it brings new breakthroughs to the field of resin system modification and is widely suitable for production needs in construction, automotive, chemical, electronic and other industries. The product, developed by a professional team, belongs to the category of cross-linked sulfonated siloxane. It appears as a colorless to pale yellow transparent liquid at room temperature without mechanical impurities. When mixed with resin systems, it does not gel or agglomerate, and does not affect the appearance of products after curing. Its core highlight is the inclusion of multi-functional cross-linking sites. A small addition can significantly increase the cross-linking density of the resin system, with a cross-linking conversion rate of over 90%, complying with the GB/T 1636 standard. By adjusting the addition amount or curing temperature, the cross-linking rate can be regulated within the range of 25-80℃, perfectly compatible with both room-temperature on-site construction and medium-temperature factory mass production scenarios.
      In terms of performance, SI-S-L003 demonstrates outstanding advantages. Tests have shown that after adding this product, the tensile strength of the material increases by more than 30% while maintaining a good elongation at break, achieving a balanced match between toughness and hardness. It effectively solves the problems of brittleness, easy cracking, soft collapse or deformation in ordinary systems. In addition, the product can greatly enhance the material's resistance to organic solvents such as acetone and ethanol, as well as weak acids and alkalis, extending the service life of products in complex media. It does not contain volatile harmful components and releases no toxic substances after curing, meeting industrial environmental protection requirements.
      Currently, SI-S-L003 has achieved mature applications in multiple scenarios. In the construction field, when used in the production of elastomeric sealants, adding 2%-4% by mass ratio of the system can increase the tensile strength of the sealant by more than 35%, with a Shore hardness of A60-A70, and no swelling or cracking after 24 hours of immersion in organic solvents. In the chemical industry, it can be used for cross-linking modification of anti-corrosion coatings for equipment and pipelines. In the industrial manufacturing field, it is suitable for the molding modification of polyurethane elastomers and epoxy composite materials, providing reliable support for industrial parts, electronic packaging, etc.
      The launch of this innovative product not only fills the technical gaps in some material modification fields but also provides an efficient solution for product upgrades in related industries. With the continuous expansion of application scenarios, its market potential will be further released.
