Premium Silica-Free Carrara Stone Surfaces SM817-GT

Short Description:

Premium Silica-Free Carrara Stone Surfaces SM817-GT Ultra-compact surfaces with crystalline clarity (99.2% quartz aggregate) have a flexural strength of 12,500 PSI and a Mohs 7+ hardness, which means they can withstand UV bleaching and impact deformation. From cryogenic to kiln temperatures (-20°C to 1100°C), edge integrity is maintained via thermal-neutral behavior (CTE 0.7×10⁻⁶/K).
Concentrated acids and alkalis are repelled by molecularly inert topology without etching or color change. Microbial colonization is eliminated by zero capillary action, as confirmed by ISO 22196 antimicrobial certification. designed for high-end interiors using a polymer matrix that is 100% silica-free and NSF-51 compliant.

Advantages

Uncompromised Performance for Elite Spaces
SM817-GT’s optical-grade quartz matrix (99.2% crystallinity) delivers 7.3 Mohs hardness and 16J impact rating (ASTM C1354), preventing surface deformation under heavy dynamic loads. Thermal shock immunity (CTE 0.7×10⁻⁶/K) maintains mitre joint integrity from liquid nitrogen exposure to forge-level heat ( -196°C / 1100°C validated).

Atomic-scale passivation withstands 98% sulfuric acid and pH14 alkalis with zero etch profiling. Sub-micron surface topology achieves 0.0001% water absorption (ISO 10545-3), enabling ISO Class 5 cleanroom compliance. Third-party verified:
✓ ISO 22196 - 99.99% bacterial reduction
✓ NSF-51 - Direct food contact certification
✓ Greenguard Gold - Ultra-low VOC emission

Engineered with zero-silica polyresin technology and 100% closed-loop manufacturing.
