What international standards does the S168 silicone sealant meet?
The S168 is manufactured under ISO 9001 quality management and formulated to meet ASTM C920 Type S, Grade NS, Class 25 requirements for elastomeric joint sealants. Its operating range of −65 °C to 150 °C and >95 % elastic recovery exceed the minimum thresholds defined by the standard for dynamic building joints.
Is the S168 silicone sealant safe for indoor use?
Yes. The S168 uses a neutral-cure (oxime) system that releases minimal volatile organic compounds during curing — significantly less than acetic-acid-cure alternatives. For VOC exposure guidelines, refer to the U.S. EPA VOC guidance. Always ensure adequate ventilation during the 24-hour full-cure period.
How does silicone sealant differ from polyurethane or acrylic sealant?
Silicone sealants like the S168 offer superior UV resistance, wider temperature tolerance (−65 °C to 150 °C vs typically −30 °C to 80 °C for polyurethane), and longer lifespan (20+ years vs 5-10 years). Polyurethane is paintable but less UV-stable; acrylic is cheapest but shrinks over time. For a deeper comparison, see the Wikipedia overview of silicone rubber properties.
