CRAYVALLAC SLT is a high performance micronised amide wax rheology modifier designed for activation-free manufacture of moisture curing methoxysilane based sealants. 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. For one component moisture curing methoxysilane based sealants, excellent slump and sag control will generally be obtained when CRAYVALLAC SLT is used at a level of 1 - 5% by mass on total formulation.
