【Product Introduction】

In rail transit lines, concrete subgrades are all designed with expansion joints. Currently, most concrete joints in China use common waterproof materials such as rubber and polyurethane. These materials can prevent water seepage and maintain the safety of rail transit in the short term, but they have disadvantages such as difficult later maintenance, poor weather resistance and short service life. The Foton Ouman high-speed rail track joint sealant has a low modulus and high elasticity, and is a product specially designed for high-speed rail transit. It has excellent weather resistance, good adhesion to concrete, and a wide range of working temperatures. It can well adapt to the vibration of rail transit lines during vehicle operation.

【Product features】

The product features of the Foton Ouman high-speed rail track joint sealant are single-component, easy to apply, and can be directly applied manually or with a pneumatic glue gun. It adheres firmly to concrete and generally does not require a primer. With low modulus and high displacement capacity, it can adapt to the expansion and shear deformation of high-speed rail track joints without causing damage to the surface of the colloid and concrete substrate. High resistance to high and low temperatures, the product can maintain excellent performance for a long time within the temperature range of -60℃ to 150℃ after curing; extremely outstanding resistance to weathering. There are basically no maintenance costs in the later stage. Non-toxic and environmentally friendly.

【Main Uses】

It is widely used for sealing expansion joints in high-speed railway tracks and airport runways.

For example: urban rail transit, Bridges, expressways, etc., to ensure the waterproofing and durability of the track structure.

【Color】

The color of the Foton Ouman high-speed rail track joint sealant is available in various colors such as black, white, and gray, and can be adjusted according to customer requirements.

【Usage Restrictions】

It cannot be used for construction in a closed environment. Not suitable for frosted or damp concrete surfaces: Freshly poured concrete must be cured in dry weather for at least 28 days before application. If it rains during the process, an additional day of drying must be added for each rainy day. For fast-completed roadbeds or when there is a need to increase the proportion of fast-drying concrete, please contact the technical service department of Ouman Company

During construction, it must be lower than the roadbed and base to prevent wear and tear from sleepers, vehicles, pedestrians and snow blowers, etc. When the surface temperature of the base material is below 4℃ or above 40℃, construction is not advisable.

The joint sealant for the tracks of the Ouman high-speed Railway complies with the following standards: Iron Standard TJ/GW119-2013

【Technology and Services】

Provide complete product technical data; Adhesion test: The Foton Ouman high-speed rail track joint sealant has excellent adhesion to most types of concrete and does not require primer treatment. However, due to the diversity of concrete configurations and the differences in surface cleanliness, on-site bonding tests should be conducted at the construction site before large-scale use to ensure good bonding.

【Packaging】

Sausage packaging: 750g/ piece

【Storage and Validity Period 】

The storage period is 12 months from the date of production when stored in a dry, well-ventilated and cool place at 0 to 27℃.
