KINGDELI Neutral Cure MS Polymer Sealant Solutions
KINGDELI Neutral Cure MS Polymer Sealant Solutions
Why choose a neutral cure MS polymer sealant?
Neutral cure MS polymer sealant combines the durable adhesion of hybrid polymers with a non-acidic curing mechanism, making it ideal for sensitive substrates and multi-material joints. KINGDELI’s neutral cure ms polymer sealant delivers strong adhesion to metals, glass, plastics, and painted surfaces while minimizing corrosion and odor. This user-friendly chemistry ensures compatibility with most building materials and reduces the risk of substrate staining or surface damage.

Engineered for high movement capability, weather resistance, and long-term elasticity, our MS polymer sealants provide excellent UV, moisture, and temperature durability. Formulated with low-VOC, solvent-free ingredients, KINGDELI’s products meet stringent environmental and performance benchmarks such as ISO 9001, ISO 14001, CE, and ASTM. With automated production capacity over 100,000 tons annually, we consistently deliver stable quality and batch-to-batch reliability.
