Why Budget Bathroom Caulks Turn Black in 6 Months

Standard acrylic or cheap acetoxy caulks use water-soluble anti-mold additives that leach out within weeks of hot showers.
Once washed away, organic soap scum penetrates the porous caulk body, causing irreversible deep black mold staining.

CHEMPU XYT932 Technology: Uses high-density, non-leaching molecular biocide integrated into the 100% silicone polymer backbone. Certified ASTM G21 Grade 0 (no visible fungal growth under 50x magnification).
