Composition: It is composed of hyperbranched epoxy compound as base material, adding special antirust pigment, various additives, solvent and hyperbranched epoxy curing agent Uses: suitable for large and medium steel structures, machinery


General Information:

Composition:two-component coating using hyperbranched epoxy compound as base material, added with special antirust pigment, various additives, solvents and hyperbranched epoxy as curing agent.

Application:Suitable for large and medium-sized steel structure, mechanical equipment, steel structure workshop, as the most basic primer.



Performance introduction

With fast drying speed (4h hard dry), early film hardness, excellent flexibility, strong adhesion, super anti-rust performance, low tendency to rust at outdoor, and excellent weather resistance (Cautions: finishing coat applied within 48h, otherwise it is apt to form float rust outdoors on rainy days).

Construction instructions

Coating methodhigh pressure airless spray, air spray, brush, roll

Thinner:High flash point exempt solvent, high flash point benzene free solvent, high flash point safe eco-friendly solvent.

Surface treatment: De-rust steel surface, remove oil and grease, clear dust, keep dry, so as not to affect adhesion and rust back.

Supporting paint: Intermediate paint: hyperbranched epoxy micaceous iron oxide intermediate paint; Finishing coat: acrylic polyurethane coating, fluorocarbon coating.


1 Coating: options include spraying, brush coating and roller coating while spraying is better. Add solvent about 20-25% of the paint when spraying. The viscosity should be controlled by the working team. Single coating dry film thickness should be controlled within 40-50μm.

2 The paint should be stirred evenly before use. Strictly follow the instruction on ratio, proper mixing, leaving 5-10 minutes before application. In order to avoid precipitation, keep stirring during all application process.

3 Attention: each batch after preparation shall be used up with 4 hours. Beyond this time frame, the viscosity gradually rises till becoming glue form. Therefore, the amount of each batch shall match the work task. The interval between two coatings should be at least 4 hours. The substrate must be sprayed evenly (no exposure of the substrate).

4 Dry spraying is more likely during hot season. Slow drying thinner is recommended to add till dry spraying wanes.
