Sikaflex 1A is a premium-grade, high-performance, moisture-cured, single component, polyurethane-based, non-sag elastomeric professional grade sealant.
This one part sealant is highly elastic, curing to a durable, flexible consistency with high cut and tear resistance. Its excellent adhesive properties let 1A bond to most construction materials without priming. A strong track record of resisting aging and weathering in demanding climates, resistance to fuel (including jet fuel) permeation, and compatibility with water, oil, and rubber based paints make this odorless, non staining adhesive a popular choice in construction applications.
Sikaflex 1A meets Federal specification TT-S-00230C, Type II, Class A as well as ASTM C-920, Type S, Grade NS, Class 25, use T, NT, O, M, G, I; Canadian standard CAN/CGSB 19.13-M87.
It's suitable for vertical and horizontal joints; readily placeable at 40F. Use as an elastic adhesive between materials with dissimilar coefficients of expansion. It is also suitable for submerged conditions, such as canal and reservoir joints.
