Product Description

Product Description

HW-735 is a water-based curing agent for common liquid epoxy resin, free of VOC and formaldehyde, cost-effective. It can be used for concrete floor coating with one surface in the middle of the ground, especially suitable for water-based epoxy self-leveling system with 1-3mm film thickness, good compatibility with cement, and can also be used for epoxy cement mortar

Product features:
1. VOC, no formaldehyde
2. Water-based self-leveling with 1-3 mm thick
3. Cost-effective, ground surface in unity
4. Light color, good resistance to yellowing
5. Construction is convenient, strong wet edges recovery ability

Formulation 1: waterborne concrete primer coating
This formula is intended for direct application to concrete as a primer and is ideal for use as a primer for RLC W27 curing agent self-leveling or mortar formulations.

B component Epoxy resin 128 Epoxy diluent AGE	45.00  5.00 50.00
C component 5.Water	84.00

Instructions for operation:
Add component B to Component A and mix at a moderate shear rate for about 2 minutes to produce a homogeneous liquid. Add component C to the mixture and continue mixing at a low shear rate for 1-2 minutes to complete the preparation of the mixture. Primer can be applied with a brush, roller, or scraper.

Formulation 2: Water-based self-leveling thick coating
The formula is very suitable for use as water-based self leveling thick coating of concrete. For best performance, apply 1 to 3 mm, but thickness can exceed 1 cm.

Operation Instructions:
Add component B to Component A and mix for about 2 minutes using a moderate shear rate to produce a homogeneous liquid. Add component C to the mixture and continue mixing at a low shear rate for 1-2 minutes to complete the preparation of the mixture.

Application Description:
It is recommended to use HW-735 water-based substrate for optimal fluidity and leveling. Apply self-leveling paint to the concrete base (primed) using a scraper or similar tool according to mixing instructions to spread the material while keeping the construction environment ventilated.
