Comparison: Verda Shield PSG 1900-IL (Lime + Graphene) Paints vs. Petroleum-Derived Paints

Feature Verda Shield PSG 1900-IL Paints (Lime and Graphene Based) Petroleum-Derived Paints (Conventional/Synthetic)
Base Composition Mineral (Artisanal Lime) and Nanotechnology (Graphene). Synthetic (Acrylic, Plastic, or Alkyd Resins) derived from petroleum.
Health and Toxicity Zero or Ultra-Low VOCs (Volatile Organic Compounds). Free from toxic substances, solvents, and plasticizers. Do not emit strong odors. High to Medium VOCs and HAPs (Hazardous Air Pollutants). Can cause irritation, headaches, and respiratory issues; they are indoor pollutants.
Climate Impact CO₂ Absorption: Absorb CO₂ from the air during their curing process (carbonation), which helps reduce the building’s carbon footprint. CO₂ Emission: Their manufacturing is energy-intensive and they release CO₂ and other byproducts during production and application.
Breathability High. They allow the wall to “breathe” (high water vapor permeability), preventing moisture and condensation buildup. Low (Plastic/Sealing). They form a plastic film that seals the wall, trapping moisture inside and facilitating the appearance of blisters or bubbles.
Biocidal Properties Naturally Fungicidal and Bactericidal. The high pH of the lime prevents the proliferation of mold, fungi, and other microorganisms, making them ideal for healthcare spaces and homes with allergy issues. Require additives (often chemical) to achieve the same resistance to mold.
Durability and Resistance Excellent. The incorporation of graphene (200 times stronger than structural steel) enhances the virtues of lime, offering:
– Greater flexibility (prevents cracking and crazing).
– Higher resistance to abrasion and washability.
– High adherence and long-term durability.		 Good to Medium. Durability depends on the quality of the synthetic resins:
– May crack or craze with structural movements or moisture.
– They are washable, but scratch resistance may be lower.
Energy Savings Contribute to savings: The lime base provides high solar reflectance and thermal emittance, reducing solar heating (especially outdoors) and aiding in the distribution of indoor temperature. Minor contribution: Their impact on thermal regulation is minor or nonexistent compared to lime.
Sustainability Fully ecological and natural. They use mineral and vegetable raw materials. They promote bio-habitability and are suitable for LEED and BREEAM certification. Not ecological. Composed of synthetic and petrochemical elements. Generate waste harmful to the environment.
Finish and Application Natural mineral matte finish (greater color depth). Easy to apply (similar to conventional paint) and does not require synthetic primers. Varied finishes (matte, satin, gloss). Application may require solvents in the case of synthetic paints.
