Product Description

Can Be Painted Extra Elongation PU Construction Adhesive Sealant

KT-5 construction adhesive is one-component sealant with high elongation and excellent elasticity. This Construction Adhesive is especially suitable for sealing joints for the multi- porous materials.

Advantages

* Excellent adhesion with former cleaned PU sealant.
* One Component, ready-to-use.
* Good adhesion with concrete materials.
* Fast cure.
* Low modulus, extra elongation.
* Good weathering resistance and high durability.
* No pollution
* Can be painted.

Application

* Sealing joints in the outer wall of precast concrete board.
* General sealing for construction joints.
* Repairing and sealing the crack of buildings.

Precautions for Use

1, Cleaning all grease,dirty,water,klunky sealant from surface,accessories,protective coatings and any pollutant left inside joints and sunken parts.Metal and glass should be cleaned by two-cloth.The solvent used will be xylene or isopropyl alcohol and observe the using rule.
2, In order to get a better bonding,user can use the primer.Suggest user prior to caking property testing by yourself or company examination center.
3, Cut nozzle to desired size,load sealant cartridge in caulking gun,place nozzle into joint by 45 degree and apply sealant into gap.
4, Smooth or tool bead in 3-5 minutes after apply sealant if needed.
5, Remove the superfluous sealant as soon as possible.
6, Tack free time in 15 minutes,fully cures in 24 hours(thickness 2mm).Warm temperature will help the curing of LZ600 after applied.

Application

* Protect joint flanks with masking tape.
* Insert back-up materials.
* Apply joint sealant with hand or air-pressure gun, avoiding air entrapment.
Level sealant with trowel to concave finish.
* Remove masking tape before sealant has started to cure.
* Clean tools immediately after operating. The cured materials can only be removed mechanically.
Note 1. The edges of corners of concrete joints are often weak because of poorly compacted concrete, thus it is desirable to use chamfers and recess the joint.
          2. The "bottom" of the joint must not restrict the deformation of the sealant since this could result in failure during the opening of the joint.
3.The depth of the joint should be adjusted by inserting a suitable joint backing material.
