CRAYVALLAC® SLT

CRAYVALLAC® SLT is a high performance micronised amide wax rheology modifier designed for activation-free manufacture of moisture curing methoxysilane based systems. Simple stirring is only necessary to get full efficiency. CRAYVALLAC® SLT is also suitable for the activation-free manufacture of moisture curing methoxysilane based adhesives. CRAYVALLAC® SLT is specially designed for the low temperature manufacture of one-component methoxysilane sealants where processing temperatures typically lie within the range 30 – 80°C. CRAYVALLAC® SLT particles are converted to an interacting network of crystalline fibres. It is this network that gives rise to the shear thinning rheology. This shear thinning characteristic provides for a low viscosity at the shear rates associated with application by extrusion, and a veryhigh viscosity under the low shear rates experienced after application. The net result is ease of application followed by excellent sag and slump resistance.

Processing Information
  • The successful manufacture of methoxysilane based sealants is very dependent on the careful control of moisture levels throughout manufacture and storage.
  • For this reason it is normal practice to pre-dry all pigments and extenders prior to dispersion with the methoxysilane polymer.
  • Alternatively, special grades of low moisture content ingredients may be used.
  • The use of vacuum processing is essentially there to prevent the take up of moisture during processing.
  • Due to the lower processing temperature used, the vacuum processing is not particularly efficient at removing unwanted water residues introduced with the raw materials.
  • Therefore a greater emphasis must be put on the pre-drying of pigments and extenders, or the purchase of special grades of low moisture content raw materials.
  • With moisture cured methoxysilane based sealants, we strongly recommend that all additives be quickly dispersed and not allowed to remain in direct contact with the resin component.
  • Prolonged contact may sometimes result in the formation of an insoluble fine skin which later appears as small particles in the final sealant.
