Createx 4030 Intercoat & Mix Additive 8 oz — water-soluble polyurethane clear for improved flow, adhesion and durability

Createx 4030 Intercoat & Mix Additive is an 8 oz water-soluble polyurethane clear that improves flow, adhesion and durability when blended with any Createx Colors paint.

Designed to be mixed into Auto Air Colors, Airbrush Colors, Wicked Colors and Illustration Colors, 4030 Intercoat converts water-based paints into an acrylic-urethane blend that levels better, resists scratches more effectively and helps paint cling to difficult surfaces. It’s a versatile mix additive and non-catalyzed clear that artists, custom painters and hobbyists use to reduce cratering, increase film strength and apply heavier wet coats without compromising finish quality.

How does 4030 Intercoat improve paint flow and leveling?

When added to Createx Colors paints, 4030 acts as a flow enhancer that reduces surface tension and helps wet paint plane out smoothly. That means fewer brush or spray marks and a more uniform finish even with heavier coats.

• Mix ratio: typically 10–30% by volume for improved flow.
• Prevents cratering when applying heavier wet coats.
• Works across all Createx water-based paint lines.

Can 4030 Intercoat help paint stick to plastics, vinyl and resin?

Yes—4030 functions as an adhesion promoter when blended with water-based paints, enhancing bonding to substrates that can be difficult to paint. It improves initial adhesion and reduces lifting or peeling when properly applied.

• Compatible with plastic, models, resin kits, vinyl and rubber.
• Mix into paint before application for best adhesion benefits.
• Not a substitute for mechanical prep; clean and scuff as needed.

Will adding 4030 change the durability or scratch resistance of finished paint?

Mixing 4030 creates an acrylic-urethane matrix that increases the cured film’s toughness versus air-dried water-based paint alone. The additive enhances abrasion resistance and helps the coating hold up better in handling and wear situations.

• Improves scratch and abrasion resistance after air drying.
• Acts as a non-catalyzed clear when used alone over compatible coatings.
• For maximum durability, combine with proper topcoats if required by the project.

How should I mix and use 4030 Intercoat for best results?

4030 is water-soluble and mixes easily into Createx Colors; typical use is 10–30% by volume, but ratios can be adjusted for sprayability and film properties. Always stir thoroughly and perform a small test spray to dial in atomization and flash times for your environment.

• Start at 10% and increase up to 30% for heavier flow and leveling.
• Test spray on scrap to confirm atomization and coverage.
• Follow normal surface preparation: clean, scuff, and allow sufficient flash time between coats.

Who is this for: Createx 4030 Intercoat is ideal for airbrush artists, custom auto and helmet painters, prop makers, scale modelers and craft hobbyists who want stronger, smoother water-based finishes. If you need better leveling, improved adhesion to tricky substrates, or a tougher air-dry coating without switching to solvent systems, this additive is a practical tool for both studio and shop use.
