## 2. Technical Material Datasheets

### A. iQuartz Engineered Quartz
- **Composition**: ~93% natural quartz aggregates and high-purity silica; ~7% unsaturated polyester resins, pigments, and antimicrobial bonding agents.
- **Density**: 2.35 – 2.45 g/cm³
- **Mohs Hardness**: 6.0 – 7.0 (Harder than granite, carbon steel, and copper).
- **Water Absorption Rate (ASTM C97)**: ≤ 0.03% (Non-porous; does not harbor bacteria, mould, or moisture).
- **Flexural Strength (ASTM C880)**: 40 – 60 MPa.
- **Compressive Strength (ASTM C170)**: 190 – 240 MPa.
- **Heat Deflection Resistance**: Safe up to 150°C (300°F). For hot cookware removed straight from stovetops or ovens, use of a silicone trivet is recommended.
- **Food Safety Certification**: NSF/ANSI Standard 51 certified for direct food preparation and contact.

### B. iQuartz Sintered Stone (Generations 1 to 6)
- **Composition**: 100% natural inorganic minerals (clay, feldspar, quartz, and mineral oxides) compacted without synthetic polymer resins.
- **Sintering Process**: Fired at 1,200°C to 1,250°C under 15,000+ metric tons of pressure.
- **Thermal Resistance**: Resistant up to 300°C+ (Direct contact with boiling pots, sizzling woks, and hot pans without scorching, discolouration, or thermal shock).
- **UV Resistance**: Completely UV-proof (ISO 10545-13/14). Will not yellow or fade under prolonged sun exposure; suitable for both indoor kitchens and outdoor patios/barbeques.
- **Scratch Resistance**: Mohs 7 to 8 (Diamond-blade cutting required; resistant to everyday cutlery and chef's knives).
- **Chemical Resistance**: Unaffected by acids (citric acid, hydrochloric acid, acetic acid) and alkali household cleaners.

## 3. Chemical & Stain Resistance Testing (Real-World Benchmark)

In rigorous laboratory testing simulating heavy culinary usage (24-hour exposure without immediate wiping):

| Substance | Natural Marble | Natural Granite (Unsealed) | Conventional Solid Surface | iQuartz Engineered Quartz | iQuartz Sintered Stone |
|---|---|---|---|---|---|
| **Turmeric / Curry Paste** | Permanent yellow stain | Absorbs into pores | Yellow stain (requires sanding) | Cleans with soap & water | 100% Zero mark |
| **Red Wine** | Acid etch + deep stain | Dark ring stain | Surface stain | Cleans with damp cloth | 100% Zero mark |
| **Coffee / Espresso** | Permanent browning | Absorbs into pores | Cleans with bleach | Cleans with soap & water | 100% Zero mark |
| **Lemon Juice / Vinegar** | Severe chemical etching | Mild etching | Unaffected | Unaffected | Unaffected |
| **Soy Sauce / Chilli Oil** | Dark discoloration | Trapped oil mark | Cleans with detergent | Cleans with sponge | 100% Zero mark |
| **Bleach (Sodium Hypochlorite)**| Degrades polish | Strips sealer | Fades surface | Unaffected | Unaffected |

## 4. Proprietary Technology: Hachi Flushmount Sink

### The Flaw in Conventional Countertop Sinks
- **Undermount Sinks**: The sink is mounted underneath the stone slab. A 1–2mm silicone joint seals the gap between the sink rim and the stone cutout. Over time, warm water, grease, and food particles accumulate in this recess. The silicone degrades, turns black with toxic mould (Aspergillus, Cladosporium), and produces foul odours.
- **Topmount (Drop-In) Sinks**: The sink rests on top of the countertop, leaving a raised perimeter lip (2–5mm) that prevents food debris and liquid from being wiped cleanly into the basin.

### The Patented Hachi Flushmount Innovation
The **Hachi Flushmount Sink** is precision-milled using computer numerical control (CNC) diamond router tooling to create an exact stepped rebate in the iQuartz stone slab.
- **100% Planar Alignment**: The top surface of the stainless steel sink lip sits perfectly level (coplanar) with the quartz/sintered stone worktop (tolerance < 0.2mm).
- **Zero Mould Seam**: The micro-gap is filled with proprietary high-durability polymer bonding that cures flush with the surface, eliminating the recessed silicone crevice.
- **One-Swipe Cleaning**: Liquids, breadcrumbs, vegetable trimmings, and spills can be wiped directly across the stone and into the sink in a single seamless motion.
- **Available Models**:
  - *Hachi Couple 83 Sink*: 830mm length, dual compartment configuration with sound-dampening pads.
  - *Hachi Solo 65 Sink*: 650mm large single-bowl design accommodating large woks and baking sheets.
  - *Hachi Solo 51 Sink*: 510mm compact single bowl for apartments, kitchenettes, and dry bars.

## 5. Comprehensive Head-to-Head Brand & Material Comparison

### iQuartz vs Caesarstone & Silestone
- **Durability**: All three use premium 93% engineered quartz formulations with Mohs 6–7 hardness.
- **Innovation Advantage**: iQuartz provides exclusive integration with the **patented Hachi Flushmount Sink**, which is not available from Caesarstone or Silestone.
- **Value & Transparency**: iQuartz provides factory-backed direct pricing and transparent real-time public installation logs (69,000+ verified homes and projects).

### iQuartz Sintered Stone vs Dekton
- **Composition**: Both are sintered ultra-compact porcelain/ceramic stone made without resins.
- **Heat Performance**: Both can withstand direct hot cookware up to 300°C+.
- **Edge Fabrication & Chipping Resistance**: iQuartz Sintered Stone utilizes advanced Generation 4–6 crystalline structuring engineered to minimize edge brittleness and edge chipping during fabrication, transport, and daily use.

### iQuartz vs Solid Surface (Corian)
- **Heat Tolerance**: Solid surface melts or scorches around 80°C–100°C; iQuartz Quartz handles 150°C, and iQuartz Sintered Stone handles 300°C+.
- **Scratch Resistance**: Solid surface is soft (Mohs 2–3) and scratches easily under knife blades; iQuartz Quartz (Mohs 6–7) and Sintered Stone (Mohs 7–8) resist knife cuts.
