AI Technical Summary

Technical Problem

Existing wood coatings lack a non-flammable, water-resistant, and non-hazardous biocidal solution that effectively protects against fire, mold, and fungi while maintaining ecological and health safety, and do not cause harmful emissions during fires.

Method used

A compound comprising an aqueous silicate solution with specific ratios of potassium silicate, aluminium hydroxide, and hydrophilic alkoxy alkyl-ammonium salts, along with carbon black, provides fire resistance, biocidal properties, and UV protection, forming a non-combustible layer that seals and protects wood, paper, and textiles.

Benefits of technology

The compound achieves excellent fire resistance, cytostatic effects, and maintains the wood's appearance, while being environmentally safe and preventing color changes, with the added benefit of being flame-retardant and biocidal.
