TLS-200 / 201 Injection Anchorage Adhesive Series

The TLS‑200 series of high‑performance injection‑molded rebar anchoring adhesives comprises two formulations: TLS‑200 and TLS‑201. TLS‑200, formulated primarily with modified epoxy resin, is suitable for reinforcing steel bar embedding in load‑bearing structures. TLS‑201, based on unsaturated resin, is designed for non‑load‑bearing applications or for situations requiring rapid curing. Both products incorporate advanced nanotechnology into their adhesive formulations, leveraging the excellent miscibility between nano‑inorganic fillers and the bonding resin to enhance the resin’s adhesive performance.

Product Details

The TLS-200 injection anchorage adhesive includes TLS-200 and TLS-201. TLS-200 is made of modified epoxy resin as the main raw materials and is suitable for the reinforcement of load-bearing structure. The TLS-201 product is made of unsaturated resin as the main raw materials. It is suitable for the reinforcement of non- load-bearing structure or the reinforcement of steel that needs fast curing. Both of them introduce advanced nanotechnology in the glue, and the mutual solubility of the nano inorganic material and the binder resin enhances the bonding property of the resin.

Product Composition

TLS-200 injection anchorage glue includes is an injection- type two- component hard plastic package. The special manual injection gun is used to fully mix and cure the resin mortar and curing agent through the mixing nozzle to achieve anchoring strength. The system composition is as follows:

Product Application Scope

Reform engineering

▲ For reinforced steel, reinforced concrete members, foundation reinforcement,additional stairs, road bridge widening, etc. of new and old concrete joints

New engineering

▲ Set the wall ribs in the reinforced concrete frame structure to avoid a large number of stencil loss due to pre- buried and construction difficulties and construction quality problems caused by the inaccurate burying position：

▲ Infill wall structure column longitudinal reinforcement.

▲ Make post-casting of the connection between the steel bar, the slab, the top, the parapet and other steel bars and the main concrete.

▲ Restore the temporary hole of the cast- in- place board.

Other engineering

▲ Embedding screws, making prefabricated piles, and fixing equipment foundations.

1. The HRB400 grade steel bar strength standard value is: fyk=400N/mm2, fstk=570N/mm2.

2. Ifa hole is made with a rhinestone, the anchoring depth is increased by onetime on the basis of the table.

3. The margin, spacing and structure of the planting barshall comply with the provisions and requirements of the“Technical Regulations for Post-Anchor of Concrete Structures”and“Code for Design of Concrete Structure Reinforcement”. The anchorage depth of the steel bars in the table shall not consider the spacing of the steel bars and the bearing capacity of the margins. The impact of specific projects is subject to design.

4. Whether the glue layer is full will directly affect the anchoring force.

5. The data in the table only considers the force of a single steel bar under a single load single working condition, and the actual anchoring depth is subject to the single design.

6. The concrete grade of the concrete used for planting steel bars should not be lower than C20, and has a certain volume. The steel bars should not be planted in weathered, severely cracked, uncompacted concrete.

7. Each group of injection-type rubber can use the calculation formula of the number of implants: n=360,000/(0.785×0.66×d2 ×h)=700,000/( d2 ×h). Where d is the Diameter of drilling hole and h is the depth of the hole, both in mm;

8. In addition to being used for concrete substrates, the planting rubber can be used for solid masonry such as various types of stone, ALC block, shale modular brick, clay brick, etc.
