It has excellent bond strength to nearly all porous and non-porous substrates without the use of a primer.

Characteristics:

• excellent adhesion and extrudability, even in adverse conditions
• AAMA approved (see below)
• 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:

• 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.

Joint dimensions:

• Minimum width: 1/4”
• Maximum width: 1 3/16”
• Minimum Depth: 1/5”
• Recommendation: 2 x depth = width

Remarks:

• 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. We recommend a preliminary compatibility test.
• We recommend a preliminary adhesion test on every surface.

Application:

• 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 AP.

Meets:

• ASTM C 920, Type S, Grade NS, Class 35, Use T, NT, M, A, G* and O**, Federal Specification TT-S00230C, Type II, Class A.
• * Soudaseal AP is not recommended to be used as glazing sealant.
• ** See recommended substrates. In accordance with AAMA 802.3-10 Type II, 803.3- 10 Type I, 805.2-10 Group C and 808.3-10.
