Axalta Industrial Speedcoat MD90 White Base Binder 4.8L – 17MD90-WBT-5 is a tintable base component used within the professional Speedcoat MD90 industrial colour mixing system.

The White Base is designed to be tinted using Axalta Pro-Stain IM tinting components according to the appropriate Axalta colour formulation.

The specified tint or combination of tints is accurately added to the White Base to produce the required finished colour. Once thoroughly mixed, the completed Speedcoat MD90 coating is ready for application.

Speedcoat MD90 is a single-pack, high-build, fast-drying coating based on a high-solids alkyd resin. It provides a full-gloss finish together with excellent chip resistance, corrosion resistance and seawater resistance.

The coating is designed for direct primerless application to correctly prepared steel used in containers, machinery and general steel fabrication, including marine, industrial and other aggressive environments.

This product is a White Base binder and must be tinted to the appropriate formula before use. Speedcoat MD90 is a 1K coating and does not require a hardener.

Colour Mixing

Speedcoat MD90 White Base is a binder and must be tinted before use.

Add the appropriate Axalta Pro-Stain IM tinting components according to the required Axalta colour formula.

Depending on the finished colour, the formulation may include:

  • Strong Black

  • Weak Black

  • White

  • Blue

  • Green

  • Red

  • Red Oxide

  • Yellow Oxide

  • Citron Yellow

  • Orange Yellow

  • Magenta

  • Other compatible Pro-Stain IM components

Always weigh each tint accurately according to the relevant Axalta formulation.

Mixing Process

1. Speedcoat MD90 White Base Binder
Use the required quantity of White Base specified by the colour formulation.

2. Add Pro-Stain IM Tint(s)
Add the specified Axalta Pro-Stain IM tinting components.

3. Mix Thoroughly
Mix until all tint components are fully incorporated and the finished colour is uniform.

4. Ready for Application
Speedcoat MD90 is a single-pack / 1K coating, therefore no hardener is required.

The published technical data states that MD90 should not normally be thinned for spray application.

Typical Applications

Ideal for:

  • Steel containers

  • Machinery

  • General steel fabrication

  • Industrial equipment

  • Structural components

  • Marine environments

  • Industrial environments

  • Aggressive service environments

  • General engineering

  • Protective coating applications

Surface Preparation

Surfaces should be:

  • Clean

  • Dry

  • Free from dirt and grease

  • Free from other contamination

  • Properly prepared before application

The published MD90 technical data specifies removal of scale and rust with preparation to a minimum of St 3 where applicable.

Application

Speedcoat MD90 is primarily intended for spray application, with small touch-up areas suitable for brush application.

Published application guidance includes:

  • Airless spray

  • Conventional spray

  • Small-area brush touch-up

  • No thinning normally required

Typical Drying Times

At approximately 20°C:

  • Touch Dry: Approx. 1 hour

  • Hard Dry: Approx. 2½ hours

At approximately 30°C:

  • Touch Dry: Approx. 40 minutes

  • Hard Dry: Approx. 2 hours

Drying times will vary depending on temperature, film thickness, airflow and application conditions.

Important

Speedcoat MD90 White Base is not a ready-to-use white coating.

It is a tintable binder/base within the Axalta Industrial colour mixing system and should be:

1. Tinted with the correct Axalta Pro-Stain IM tint(s)
2. Thoroughly mixed to produce the required finished colour
3. Applied as a single-pack Speedcoat MD90 coating

No hardener is required.

Always follow the appropriate Axalta colour formulation and current technical data for the finished Speedcoat MD90 coating.
