product introduction
GT800 silicone caulking sealant is a single component, non-sagging type, specially designed for the long-term weatherproof sealing of the expansion joints, shrinkage joints and longitudinal joints of the ballast less track (high-speed railway or intercity railway) and other concrete pavement surface. It has low modulus and good expansion and recovery characteristics, which can adapt to the displacement of concrete joints. Accelerated weathering tests show that its excellent weather resistance is fully qualified for the harsh test of high temperature, low temperature and strong ultraviolet environment of concrete pavement.product characteristics
1, Easy to use: single packaging, easy to use, in the usual construction temperature range, good extrusion applicability;
2, No primer: neutral curing, chemically compatible with concrete, solid chemical bonding to concrete, generally do not need to use primer;
3, Long service life: excellent long-term weather aging resistance, will not be damaged by sunlight, rain, snow, ultraviolet, ozone; Excellent resistance to high and low temperatures, the rubber strip formed after curing will not significantly harden or become brittle at -40°C and still maintain good elasticity, and will not flow or degrade at +150°C high temperature;
temperature;packaging and color
Use composite soft film packaging, net content 590ml.
Grey or other color as required by the user.Precautions for use
1, Construction should not be carried out in bad weather;
2, Not suitable for frosty or wet surfaces;

4, Should not be used for continuous water and oil immersion places;
5, It should not be used in densely unventilated places, because the sealant needs to absorb moisture in the air to cure;
6, When the surface temperature of the material exceeds 40°C, it is not suitable for construction;
7, The newly poured concrete should be maintained in dry weather for at least 7 days. In case of rainy weather, each rainy day must correspond to an additional dry day to ensure at least 7 days of dry maintenance; Need to be completed quickly or in case of fast drying type concrete, please contact Hengbao chemical technical service personnel;
8, Sealant construction and installation, should be lower than the road to prevent wear,
9, Base material use restrictions: not suitable for copper 'lead, galvanized metal surface and polycarbonate materials.Safety Instructions
