- Ready-to-Use Product Features
- Characteristics
- excellent adhesion on porous and non porous substrates
- high performance mechanical properties
- permanent elastic after full cure
- self leveling
- no bubble formation within sealant even in high temperature and humidity applications
- color stable and UV resistant
- ecological advantages - free of isocyanates, solvents, halogens and acids
- minimal health and safety considerations
- can be painted with water based paints and many other systems (to be tested)
- good extrudability even at low temperatures
- excellent weather resistance in all climates can be used on damp or moist substrates
- primerless adhesion on many different substrates (except where water pressure may occur) almost odorless
- Direction for use
Substrates
- Surface Preparation: clean, dry, free of dust and grease, free of chipping paint.
- Priming: Porous surfaces in water loaded applications
- should be primed with Primer 150.
- Surface Activator may be used to pretreat non-porous surfaces.
- We recommend preliminary compatibility tests previous to application.
Resistance to chemical agents:
Good resistance to water, aliphatic solvents, mineral oils, grease, diluted inorganic acids and alkalis. Poor resistance to aromatic solvents, concentrated acids, chlorinated hydrocarbons.
Horizontal Joint dimensions:
- Minimum width: 1/4”
- Maximum width: 1 3/16”
- Minimum Depth: 1/5”
- Recommendation: 2 x depth = width
Applications
- Method: Manual- or pneumatic caulking gun. Application
- temperature: -35°F to +140°F. Cleaning: with IPA
- immediately after use and before curing. Repair with:
- Soudaseal SL.
Applications & Uses
- Applications

- Compatible Substrates & Surfaces
- Cure Method
- Applications
- sealing of horizontal joints in building and metal work industry.
- sealing of horizontal overlap joints between panels in automotive applications.
- Remarks
May be painted, however due to the large number of paints and varnishes available we strongly suggest a compatibility test before application. The drying time of alkyd resin based paints may increase. Can be applied to a wide variety of substrates. Due to the fact that specific substrates such as plastics, like polycarbonate, etc. may differ from manufacturer to manufacturer, we recommend preliminary compatibility tests. Bonding plastics like PMMA (ie Plexi® glass) and polycarbonate (ie Makrolon® or Lexan®) in stress loaded applications can give rise to stress cracking and crazing in these substrates. The use of Soudaseal SL is not recommended in these applications.
