Technical Name: Speco 4-in-1 Hygiene Finish for Refurbished Furniture
Key Technology: Nano-Encapsulated Organo-Silane Coating with Upcycled Marine Biopolymer & Amino Acid Complex

Primary Function

Sitwork’s refurbished office tables and chairs are treated with Speco’s proprietary 4-in-1 Finish, a high-performance protective solution that transforms pre-loved furniture into a premium, wellness-oriented choice for modern workspaces.

This advanced finish provides comprehensive hygiene assurance by combining:

• Antibacterial protection (ISO 22196 certified)
  
• Anti-Mould resistance (climate-adaptive barrier)
  
• Anti-Odour neutralization (microbial-source detoxification)
  
• Anti-Formaldehyde detoxification (formaldehyde capture & neutralization)
  

Together, these four functions safeguard employee health, reduce cross-contamination risks, and extend the useful life of refurbished furniture—aligning with sustainability and workplace wellness goals.

Mechanism of Action

1. Upcycled Marine Biopolymer Matrix

• Derived from seafood by-products, this sustainable biopolymer acts as a natural chelating agent.
  
• Captures and binds airborne formaldehyde molecules, converting them into stable, inert structures.
  
• Supports circular economy by upcycling waste into high-value functional chemistry.
  

2. Functional Amino Acids

• Amino acids with reactive amine groups bind formaldehyde via Schiff base formation.
  
• Converts harmful aldehydes into harmless compounds while also reducing odour-causing VOCs.
  

3. Antimicrobial & Anti-Mould Barrier

• Organo-silane chemistry permanently anchors the coating to porous and high-touch surfaces.
  
• Prevents bacterial regrowth, mould germination, and microbial odour formation for up to 3 years.
  

4. Nano-Silane Anchoring System

• Forms covalent bonds with laminates, painted wood, and powder-coated surfaces.
  
• Transparent, durable, and long-lasting finish that protects without altering furniture aesthetics.
