- Ready-to-Use Product Features
- Characteristics
- Excellent adhesion and extrudability, even in adverse conditions.
- High performance mechanical properties.
- Flexible elastic rubber movement accommodation up to 100 to -50%.
- Very low modulus, hence can handle extreme joint movement.
- No bubble formation within sealant even in high temperature and humidity applications.
- Very easy to tool and finish.
- Color stable and U resistant.
- Ecological advantages - free of isocyanates, solvents, halogens and acids.
- Minimal health and safety considerations.
- Can be painted with all water based paints and many other systems (to be tested).
- Excellent weather resistance in all climates.
- Primerless adhesion on many different substrates (except where water pressure may occur).
- Almost odorless
Applications & Uses
- Applications
- Application Area
- Applications
- Expansion and connection joints in the building industry.
- Sealing of joints in prefabricated buildings, movement joints in high rise constructions, sealing between window and door frames.
- Flexible joints in marine and automotive applications.
- Applications that should be painted with water based paints.
- Curtain wall constructions
- Panel walls
- Aluminum, vinyl and wood window frames
- Sealing in sanitary applications
- Substrates
- Recommended Surfaces - EIFS, stucco, aluminum, concrete, masonry, wood, stone, glass, vinyl, fiber cement siding.
- 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.
- 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
- Should not be used as a structural sealant.
- 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.
- 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 to 90°F
- Cleaning - With IPA immediately after use and before curing
- Repair - With SoudaSeal 150 LM
