TLS-701 Structural Epoxy Adhesive for Precast Segmental Construction

TLS-701 Structural Epoxy Adhesive for Precast Segmental Construction

TLS-701 structural epoxy adhesive for precast segmental construction is A/B two-component structural adhesive, which is compounded by modified epoxy resin, modified amine curing agent and various organic and inorganic materials. It is used for the joint bridging machine to carry out the prefabricated segment assembly and suspension construction technology of the joints, the general reinforced concrete prefabricated components and the surface defects of the components.

Product Details

Product Features

▲ High strength, high elastic modulus, acid and alkali resistance, corrosion resistance

▲ Good thixotropic performance, easy to stir and smudge, no sag, no dripping

▲ Strong bonding ability with concrete, can effectively transfer load

▲ Long operating time, but fast curing speed, strength can be quickly increased

▲ It can be wet and low temperature construction, and it has stronger adhesion under dry conditions.

▲ The bonding surface is dense and does not seep water, which will not cause steel corrosion.

▲ good toughness, impact resistance, fatigue resistance

▲ Safe to use, non-toxic

Construction Methods and Key Points

Notes

▲ Each time the glue should not be too much.

▲ The glue surface should be dry, dust- free and free of grease.

▲ The glue surface should be roughened.

▲ It is not suitable to work in a humid environment to avoid the humidity of the air causing the surface ofthe gel to stick.

▲ Do not let children touch, eat by mistake.

▲ Pay attention to ventilation in the construction environment to avoid fire.
