Frequently Asked Questions

Goldshield uses an organosilane-based molecule that bonds covalently to treated surfaces. Once bonded, the molecules form a dense array of positively charged nano-scale projections. When microorganisms contact the surface, the electrostatic charge disrupts their cell membranes, destroying them. Because the mechanism is purely physical rather than chemical, no active ingredients are released into the environment.

Because Goldshield's mechanism is physical — it physically disrupts the microbial cell membrane — rather than chemical, microorganisms cannot develop resistance through genetic mutation in the way they can with antibiotic or conventional biocide treatments. The electrostatic disruption mechanism does not rely on a specific molecular target that can mutate.

Goldshield's technology has been evaluated against a range of bacteria, fungi, and mould. The physical disruption mechanism is effective against gram-positive and gram-negative bacteria, as well as common fungi and mould species. For specific efficacy data relevant to your application, please consult our technical team or ask the AI assistant.

Once the Goldshield compound has cured and bonded to the surface, it is in a fixed, non-leaching form. Cytotoxicity testing of the cured, surface-bonded compound has shown no significant toxic effect on mammalian cells at concentrations relevant to treated surface contact. The product is formulated for use in environments with regular human contact, including hospitality, healthcare, and education settings.

No. Unlike conventional biocides that work by slowly releasing active ingredients (leaching), Goldshield's technology is non-leaching. The active compound is permanently bonded to the surface and does not migrate into the surrounding environment, water, or air. This is one of the key differentiators of the technology from traditional antimicrobial treatments.

GS75 is Goldshield's primary formulation for hard surfaces including countertops, walls, floors, door handles, and high-touch areas. It is a ready-to-use liquid that can be applied by spray or wipe-on method. For spot treatment or on-the-go use, GS85 Wipes offer the same antimicrobial formula in a convenient pre-moistened format.

GS5 is specifically engineered for soft substrates including fabrics, textiles, upholstery, and carpets. It bonds at the fibre level to provide wash-durable antimicrobial protection. GS5 can be applied by spray, soaking, or as a laundry additive, making it suitable for hotel linens, uniforms, soft furnishings, and any high-contact fabric surface.

Durability depends on the product and the substrate. GS75 on hard surfaces can provide protection for up to 90 days under normal conditions, though this may vary depending on cleaning frequency, surface type, and environmental factors. GS5 on textiles retains antimicrobial activity across multiple wash cycles. Regular monitoring and re-application protocols are recommended for high-traffic environments.

Application method depends on the product and substrate. GS75 for hard surfaces is applied by spray or wipe-on, then allowed to dry. GS5 for textiles can be applied by spray, soaking, or as a laundry additive. GS85 Wipes are applied directly to surfaces. All products should be applied to clean, dry surfaces for optimal bonding. Specific dilution ratios and dwell times are provided in the product technical data sheets.

No. Goldshield is designed to complement, not replace, regular cleaning protocols. Standard cleaning removes visible dirt, debris, and organic matter from surfaces. Goldshield then provides a continuous antimicrobial barrier on the cleaned surface between cleaning cycles. The two approaches work together: cleaning removes contaminants, and Goldshield inhibits microbial growth on the treated surface.
