Identification & Functionality

Features & Benefits

Characteristics
  • AAMA approved (see below)
  • excellent adhesion and extrudability, even in adverse conditions
  • high bond strength on nearly all surfaces
  • high performance mechanical properties
  • flexible elastic rubber - movement accommodation up to +/-50
  • low modulus - 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 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
Direction for use

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 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.

Joint dimensions:

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

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 50 LM. 

Applications & Uses

Application Method
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
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.
