GUIBAO 877 Modified Mastic

Inquiry

GUIBAO 877 Modified Mastic is a modified elastic silicone anti-corrosion adhesive that provides excellent acid and temperature resistant properties. The technology in this product is highly advanced when compared to similar international technologies. GUIBAO 877 modified mastic has been used in many successful anti-corrosion projects for coal-fired power plant chimneys since 2005.

• Two-component, fast curing and bonding rate
• Excellent resistance to temperature extremes, unaffected performance in environment from –50 ℃ to +200 ℃ after curing
• Excellent corrosion-resistant ability. Permanent use in desulphurizing chimneys in some power plants, where the air is saturated with wet flue gas
• Great cohesiveness. Good adhesion to a wide range of substrates, such as concrete, acid-resistant brick, steel substrate, fiberglass, ceramics and so on. Extremely wide scope of application
• Exemplary resistance to abrasion and erosion of the flue gas dust and the gas flow with high velocity
• Good flexibility and adaptability to stress caused by the expansion and contraction of different substrates. No cracking, no shedding
• Excellent resistance to aging. Generally speaking, the service life can reach up to 30 years
• CECC Certification
• Free from harmful volatile gases, meaning it is safe to be around and causes no environmental pollution

• Anti-corrosion, bonding and filling of foam glass bricks, vitrified ceramic tiles, corrosion-resistant alloy materials in thermal power plant chimneys and flue lining systems.
• The bonding of all kinds of fire-resistant materials, thermal insulating materials and corrosion-resistant materials.
