Sikafloor-161 (AB) | MCT CHEMICALS | SIKA PAKISTAN

DESCRIPTION
Sikafloor®-161 is an economical, two-component epoxy resin with low viscosity, ideal for use in hot and tropical climates.

USES
Sikafloor®-161 should only be used by experienced professionals. It is designed for priming concrete substrates, cement screeds, and epoxy mortars, as well as for use on low to medium absorbent surfaces. It also serves as a primer for Sikafloor®-263 SL, Sikafloor®-264 flooring systems, and Sikalastic®-800 series. Additionally, it works as a binder for leveling mortars and mortar screeds, and as an intermediate layer under Sikafloor®-263 SL and Sikafloor®-264.
