CRAYVALLAC SLX is a high performance micronised amide wax rheology modifier designed for the low temperature manufacture of moisture curing methoxysilane based sealants. CRAYVALLAC SLX is also suitable for the low temperature manufacture of moisture curing methoxysilane based adhesives. CRAYVALLAC SLX is specially designed for the low temperature manufacture of one-component methoxysilane sealants where processing temperatures typically lie within the range 60 - 90°C. For one component moisture curing methoxysilane based sealants, excellent slump and sag control will generally be obtained when CRAYVALLAC SLX is used at a level of 1 - 5% by mass on total formulation.
