- Characteristics
- Excellent adhesion and extrudability, even in adverse conditions.
- AAMA approve
- High bond strength on nearly all surfaces.
- High performance mechanical properties.
- Flexible elastic rubber movement accommodation up to ±35%.
- No bubble formation within sealant even in high temperature and humidity applications.
- Very easy to tool and finish.
- 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).
- Excellent weather resistance in all climates.
- Primerless adhesion on many different substrates (except where water pressure may occur) almost odorless.
Applications & Uses
- Markets
- Applications
- Cure Method
- Applications
- Expansion and connection joints in the building industry.
- Sealing of joints in prefabricated buildings.
- Movement joints in high rise construction.
- Sealing between window and door frames.
- Flexible joints in automotive applications.
- Applications that should be painted with water based paints.
- Substrates
- Recommended Surfaces - EIFS, stucco, aluminum, concrete, masonry, wood, stone, glass, vinyl, fiber cement siding, metals, PVC, kynar 500.
- 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 pre-treat nonporous 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.
- Product Application
- Method - Manual or pneumatic caulking gun.
- Application temperature - 40°F to 90°F.
- Cleaning - With IPA immediately after use and before curing.
- Repair - Using Soudaseal AP
- 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.
- Contact with plasticizer containing plastics (e.g. flexible PVC, butyl rubber, EPDM) can lead to incompatibilities, such as discoloration or loss of adhesion.
