Product Description

G-tech®B900 Superhigh elastic sealant for caulking and water sealing

Specification: 600ml/piece, 20 pieces/box
Color: usually grey; the color can be customized
Warranty: 10 months

Product Overview:
G-tech®B900 Superhigh elastic sealant for caulking is single component, which can be used after opening, and is environment-friendly; it is paste like and does not sag; it can be used not only for horizontal joint sealing, but also for vertical joint sealing, which is convenient to use. It has good chemical compatibility with concrete, asphalt concrete, metal and so on, and the bonding is firm. Generally, there is no need for bottom coating treatment. It has the characteristics of neutrally curing at normal temperature, high and low temperature resistance and good aging resistance after curing, high stability, low modulus, high elasticity, etc. Artificial accelerated climate aging test shows that it has excellent weather resistance and can fully cope with the harsh outdoor environment test of high and low temperature and strong ultraviolet.

Scope of application:
1.Waterproof sealing of subway, tunnel, bridge, civil air defense, underground pipe gallery and other projects;
2.Caulking and water sealing at joints of roads, overpasses, houses, etc;
3.Waterproof sealing of deformation joints, expansion joints and general cracks of other buildings.

Performance advantages:
Long service life: excellent long-term weather aging resistance, will not be damaged by the influence of sunlight, rain, snow, ultraviolet light and ozone; it has strong corrosion resistance, acid and alkali resistance, and is resistant to various chemicals. It has a wide pH tolerance range of 2-12.
High displacement capacity: After curing, soft elastic colloid is formed with strong adhesion to the substrate, and it can freely follow the expansion and shear deformation of substrates, such as concrete joints, without being damaged.
Easy construction: can be used after opening; it is paste like and does not sag; it can be used not only for horizontal joint sealing, but also for vertical joint sealing; it has good chemical compatibility with concrete, asphalt concrete, metal and so on, and the bonding is firm; generally, there is no need for bottom coating treatment.
Excellent high and low temperature resistance: elastic colloid is formed after curing; within the temperature range of -60ºC-200ºC, it is not brittle or cracked under low temperature, and it does not flow or melt under high temperature, maintains good elasticity.
Environmentally friendly and free of VOC: the product does not contain solvents and volatile substances. It is naturally solidified at room temperature, does not release toxic substances, does not contain methanol and heavy metals. The product is environmentally friendly, does not pollute water and soil, and does not corrode the bonded substrate.
