Applications & Uses
- Markets
- Applications
- Compatible Substrates & Surfaces
- Applications
- Sealing of joints in building and metal work industry.
- Sealing of overlap joints between panels in automotive applications.
- Substrates
- Surface Preparation - clean, dry, free of dust and grease, free of chipping paint, no adhesion on PE, PP, PTFE and bituminous substrates.
- Priming - Porous surfaces in water loaded applications should be primed with primer 150.
- Surface activator may be used to pretreat non-porous surfaces.
- 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.
- Limitations
- 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.
- Should not be used as a glazing sealant.
- Should not be used for continuous immersion in water.
- Do not apply to freshly treated wood; treated wood must have been weathered for at least 6 months.
- Lower temperatures and humidity will extend curing time.
- Product Application
- Method - Manual- or pneumatic caulking gun.
- Application temperature - 34°F - 90°F.
- Cleaning - with IPA immediately after use and before curing.
- Repair - With SoudaSeal SL
