Two-component epoxy primer and binder for concrete floors. Provides excellent adhesion and a strong base for subsequent Sikafloor® coating systems. Suitable for industrial and commercial flooring applications.

Sikafloor®-161 G

Product Description

Sikafloor®-161 G is a low-viscosity, two-component epoxy resin-based primer and binder (Component A and Component B), specially designed for use in hot and tropical climatic conditions.

It offers excellent penetration into concrete pores, enhances substrate strength, and provides strong adhesion, making it suitable for preparing surfaces before applying epoxy flooring systems.

Main Applications

1. Primer for Concrete Surfaces: Used as a primer for concrete substrates, cement screeds, and epoxy mortar to improve adhesion and prepare the surface for subsequent coatings.

2. Binder for Epoxy Mortar: Used as a binding agent for preparing epoxy levelling mortar and epoxy repair mortar.

3. Base & Bonding Layer: Used as a primer or bonding layer beneath epoxy and polyurethane flooring systems, such as:

• Sikafloor-263 SL

• Sikafloor-264

Key Specifications & Properties

1. Mixing Ratio: 4.71:1 by weight (Component A : Component B), according to the specified product mixing ratio.

2. Packaging: Typically supplied in complete kits with a total weight of 28 kg.

3. Solid Content: 100% Total Solids Epoxy.

4. Application Temperature: Ambient and substrate temperatures must be between +10°C and +35°C.

5. Humidity & Dew Point Requirements:
