  • Brand Name: mimdy
  • Main Raw Material: Silicone


CO652 Concrete joints silicone sealant

1.One component, neutral curing, good extrusion and thixotropy , easy to use.
2.Excellent unprimed adhesion and bonding to concrete.
3.Abrasion resistant.
4.Low modulus-able to stretch in the joint with little force, so it can better protect the concrete surfaces from being damaged .
5.Resilient-once cured, strong anti-embedding performance, preventing gravels and other incompressible into the joints which may result in joint edge failure.
6.High movement capability-able to accommodate the extension and contraction, and shear deformation of concrete joints without itself being destroyed.
7.Remains flexible over a temperature range of -58°F(-50℃) to 302°F(150℃).
8.Excellent weatherability and high resistance to ultraviolet radiation, heat and humidity, ozone and temperature extremes.

Main applications:
Sealing for concrete joints.

1.Can not be used in structural glazing applications or where the sealant is intended as an adhesive.
2.Is not appropriate for all will be leaking oil, plasticizer or solvent surface.
3.Is not suitable for airtight place, because the silicone sealant need absorb air gas in the water cure.
4.Not for frost or wet surface.
5.Is not suitable for the place of continuous immersion or year-round moisture.
6.Is not suitable where movement capability greater than ±25% is required.
7.Hasn't performed adhesion and compatibility tests on project substrates and all accompanying accessories.

Typical properties:
These values are not intended for use in preparing specifications.

1.Surface preparation: Sealants may not adhere or maintain long-term adhesion to substrates if the surface is not prepared and cleaned properly before sealant application. Using proper materials and cleaning procedures is vital for sealant adhesion.
2.Cleaning materials: clean, fresh solvent; clean, white cloths free of lint or other lint-free wiping materials; primer (when required).
3.Cleaning procedures: Remove all loose material (such as dirt and dust), plus any oil, frost or other contaminants from the substrates to which the sealant will be adhered. Do not use detergent to clean the substrate as residue may be left on the surface. Wet one rag with solvent and wipe the surface with it, then use the second rag to wipe the wet solvent from the surface before it evaporates. Change the cleaning rags frequently, as they become soiled. If cleaned areas are again exposed to rain or contaminants, the surface must be cleaned again.
4. Primers:CO652 Concrete Joints Silicone Sealant will bond to many clean surfaces without the aid of a primer. For difficult-to-bond substrates, the use of a primer or special surface preparation should be evaluated.

Emergent Treatment:
Keep out of reach of children. Once it contacts skin or eye by accident, rinse the affected part with water for 15 minutes or turn to doctor for help immediately.
