DynatrolTM I-XL is a moisture-curing, single-component non-sag polyurethane sealant. It is designed to maintain an effective bond and seal between materials of similar and dissimilar surfaces, porosities and coefficients of expansion.
Limitations: DynatrolTM I-XL should not be used:
-
as a cap, heel or toe bead in certain glazing installations with high-perfor- mance glass or plastic.
-
in joints less than 1/4”(6mm) in depth.
-
in joints where contact may be made with polysulfide sealants.
-
in areas exposed to harsh chemicals.
-
on certain architectural paints and finishes without laboratory or field testing.
-
in horizontal joints subject to vehicular traffic unless protected by a wearing surface.
Although DynatrolTM I-XL is considered a paintable sealant, due to variability in paint products and their raw materials, installation conditions, installation tech- niques, as well as primers, it is required that the contractor who applies paint, pretest paint on sealant to determine suitability. Contractor is responsible for test as well as results. Oil based paints can exhibit a slow/non-curing condition.
