This product uses nano-grade high-purity lithium silicate raw materials, which can penetrate into the pores of porous cultural relic substrates and form a stable chemical bond with the minerals in the substrates, without changing the appearance and material properties of cultural relics. The visible light transmittance is as high as 95%, which will not cover the original color of cultural relics. At the same time, it has excellent air permeability, allowing the internal water vapor of cultural relics to naturally escape, avoiding the cracking and falling off caused by excessive internal pressure of substrates caused by traditional sealants. It has excellent anti-UV aging performance, and will not yellow or crack within 10 years, suitable for long-term protection of precious cultural relics.
The visible light transmittance is ≥95%, water vapor transmission rate is ≥1000g/(㎡·24h), pH value is 7.0-8.0 neutral, UV blocking rate is ≥90%, no yellowing performance meets ISO 105-B02 standard, packaged in 1kg light-proof plastic bottles, shelf life is 18 months, stored in a cool and dry place, avoid high temperature and direct sunlight, and diluted to 5% concentration for construction.
It is mainly suitable for the protection and restoration of ancient murals, stone carving relics, ceramic cultural relics and masonry building sites. It can be used for the sealing protection of cultural relics in museum cultural relic display cabinets, and also for the protection of outdoor cultural relic relics. It is suitable for cultural relic protection institutions, museums and ancient building restoration teams, and meets the standard requirements of the International Council of Museums.
