1. Introduction

  • KORESEAL SL1000 is an one component, neutral curing (oxime) silicone sealant with outstanding adhesion to general exterior of building especially window perimeter sealing and joint of aluminum complex panel .


2. Application

  • Sealing of joint between a window frame(PVC, AL) and wall(Concrete)
  • Sealing of joint of Concrete panel (ex. Reinforced Concrete ,Pre-casted Concrete)
  • Joint of aluminum complex panel.


3. Main Properties

  • 1-Component & Non-Slump / Good Adhesion to most substrates / Good weatherability and gun workability regardless of seasons


4. Packaging

  •  SL1000 Sealing Windows Perimeter 500ml Al Sausage


5. Characteristics

  •  A one-component sealant that can be used regardless of seasons (good gun workability)
  • Remains flexible after being cured even at low (-50 ℃) and high temperatures (150 ℃).
  • Exhibits excellent safety against temperature changes due to high elongation rate and resilience.
  • Adheres well to most substrates, but the recommended primer should be used in the case of certain substrates as well as concrete, brick and other porous substrates.


6. Properties

  •  Tested at 23 ℃, 50 % relative humidity
  • ASTM : American Society for Testing and Materials Notice
  • These property values are tested in a lab condition. They might be changed by testing and storage conditions.

7. How to use

  • CLEAN ALL JOINT SURFACE - Clean all substrate surface and regarding dust oil, frost and any contaminants Wipe polluted parts using solvent and a piece of cloth. Do not use detergent, soap and water.
  • INSTALL BACK-UP MATERIALS - Backer rod materials such as closed cell polyethylene type can be used as the base of the joint to control sealant depth.
  • MASK ADJACENT SURFACE WITH MASKING TAPE - Masking tape will ensure a clean, neat appearance and reduce clean up by protecting surrounding areas from excess sealant.
  • PRIMING - Primer may be needed for optimum adhesion to some substrate surface.
  • APPLYING SEALANT -Applying sealant deeply into joint. Sealant must be filled into the joint cavity perfectly.
  • TOOL SEALANT - Tool sealant immediately after sealant application. It helps to provide smooth and flat finish and to ensure that the sealant wets the sides of the joint without any voids.
  • REMOVE MASKING TAPE - Remove masking tape prior to forming sealant surface skins.
  • CLEANING - Clean all stuffs around sealant cure area and do not touch when sealant is curing.


9. Limitation

SL1000 should not be applied :

  • To building materials of adhesive hindrance or discoloration that bleed oil, plasticizer or solvent and so on.
  • In totally confined spaces.
  • When substrate surface temperatures exceed 50 ℃ and under 5 ℃.
  • To wet surface (on frost-laden or damp surfaces).
  • Humid day(over 85% relative humidity day).
  • For continuous immersion in water or in below-grade applications.
  • Surface in direct contact with food.
  • For continuous high pressure and high temperature.
  • Interior fire prevention section.
  • Joint region that wear is expected by physical friction.
  • Region that paint is required to sealant. Structural glazing
  • Not recommended for use on polycarbonate plastic sheeting, self-cleaning glass, non-staining fluorine coating suitability for use on other type of plastic should be tested adhesion prior to application.

11. Handling Precautions

  •  Use at room temperature in the range of 30 to 80 % relative humidity.
  • Time for complete cure is depend on the thickness of sealant applied.
  • Adhesion may decline in case of the substrate contaminated. For the best adhesion, clean surfaces thoroughly with solvent before applying the product.
  • Wear eye protection and protective gloves when handling this product.
  • Maintain adequate ventilation in the work place at all times.
  • Keep in place that child’s hand does not touch and never ingest or do not touch in skin
  • Keep or do work at neighborhood of heat or fire.
  • Do not use besides service. / Do not inflict shock in receptacle.
  • Avoid direct ray of light and keep in state that is tightly shut in place that moisture is less.
  • Do not mixing with other products.
  • Wash your skins cleanly after work.
  • As change in quality can be at long term storage, use in validity.
  • Do not use defected back-up materials. It might induce air bubble.


12. Safety and Storage

  • Store in original unopened containers in a dry place. Temperature should not exceed 25 ℃ for prolonged periods. (Recommended at 5 ~ 25 ℃)
  • Please, refer product MSDS for more details regarding safety information.
