Createx Intercoat & Mix Additive 8 oz — 4030 water-soluble polyurethane clear for improved flow & scratch resistance

Createx 4030 Intercoat & Mix Additive 8oz is a water-soluble polyurethane clear that blends with Createx Colors to improve flow, adhesion, leveling and scratch resistance.

Whether you airbrush custom automotive accents, build scale models, or work on vinyl and rubber surfaces, 4030 Intercoat is formulated to modify Createx water-based paints into a tougher, more workable finish. When combined with Auto Air Colors, Airbrush Colors, Wicked Colors or Illustration Colors, this additive converts the paint into an acrylic-urethane system that handles heavier coats without cratering and increases the coating’s resistance to wear after air drying.

How does 4030 Intercoat affect paint flow and finish?

Adding 4030 reduces surface tension and improves how paint spreads, producing smoother, more even layers and reducing brush or atomizer marks. It helps paints lay down in heavier passes without developing craters or orange peel, making multi-coat jobs faster and more predictable.

• Improves wetting and leveling for fewer visible defects.
• Enables heavier coats with less risk of surface irregularities.
• Helps achieve uniform gloss and smoother transitions between coats.

Can I use 4030 with all Createx paint lines and at what ratios?

4030 is compatible across Createx paint ranges — Auto Air, Airbrush, Wicked, and Illustration Colors — and can be mixed at flexible ratios based on your needs. Typical use falls between 10% and 30% by volume; lower amounts favor subtle flow improvement, while higher proportions increase leveling and durability.

• Mix 10% for light flow enhancement without major property changes.
• Use 20–30% to boost leveling and abrasion resistance for topcoats.
• No catalyzation required; it functions as a non-catalyzed clear additive.

Will 4030 improve adhesion on plastics, vinyl and resin parts?

Yes — as a polyurethane-balancing clear, 4030 acts as an adhesion promoter when blended into water-based Createx paints. That improves paint bond to challenging substrates like plastics, models, resin kits and rubber, reducing the chance of flaking or peeling under normal use.

• Enhances initial adhesion to slick or flexible surfaces.
• Reduces lift and edge flaking on vinyl and rubber components.
• Useful for hobbyists, model builders and custom automotive trim applications.

How does 4030 affect durability and scratch resistance?

When mixed into Createx paints, 4030 creates an acrylic-urethane blend that increases hardness and scratch resistance after air drying. This additive doesn’t require baking or catalysts to add durability, making it convenient for projects where post-cure heat processes aren’t feasible.

• Improves scratch and abrasion resistance compared with air-dried paint alone.
• Strengthens topcoats for items that see handling or light wear.
• Preserves paint flexibility on flexible substrates while enhancing toughness.

Who this product is for: 4030 Intercoat suits hobbyists, airbrush artists, custom automotive painters and industrial users who work with Createx Colors and need better flow, adhesion and durability without switching to solvent-based systems. It’s helpful for anyone finishing models, helmets, vinyl decals, signage, or vehicle accents who wants a stronger, smoother water-based coating that resists cratering and light abrasion. Produced in the U.S.A., water-based and compliant with ASTM D-4236, the 8oz bottle is sized for frequent touch-ups and small-to-medium projects.
