Sherwin-Williams Ultra 9K U9130 HS Violet Waterborne Automotive Basecoat

Sherwin-Williams Ultra 9K U9130 HS Violet is a professional waterborne base colorant for automotive refinish color formulation. It is used within the compatible Ultra 9K mixing system to make controlled blue-violet adjustments in solid and metallic automotive colors.

U9130 is designed to create a blue cast on both the face and flop of a color. Its relatively weak tinting effect makes it suitable for fine color correction rather than large-scale color changes. Colorists can use it to cool a formula that appears too red or warm, or to guide blue, violet and selected cool metallic colors toward the required visual direction.

The colorant is supplied in a 1 L package and is suitable for professional body shops, dealership repair departments, automotive paint distributors and color-mixing centers.

• Controlled blue-violet correction: Helps move solid and metallic formulas toward a cooler blue direction.
• Face and flop influence: Supports color adjustment when the panel must be evaluated from both direct and angled viewing positions.
• Mild tinting behavior: Allows gradual micro-adjustment and helps reduce the risk of over-correction during color matching.
• Professional Ultra 9K system component: Designed for use as part of a compatible Sherwin-Williams Ultra 9K waterborne color system.
• Suitable for complex refinishing work: Useful for OEM-style color matching, spot repair and spray-out panel testing.
• Practical distributor format: 1 L cans with 3 cans per carton for professional workshop supply.

U9130 is a waterborne automotive refinish colorant used as one component in a formula-based basecoat mixing system. It is not intended to be applied as a standalone ready-to-spray topcoat. The final color should be prepared according to the applicable Ultra 9K formula and system instructions.

System position: Waterborne colorant → formula mixing → spray-out verification → basecoat application → compatible clearcoat system.

U9130 HS Violet provides a blue-violet color direction. It can help cool a formula that is visually too red, warm or insufficiently blue.

The product can influence both the face color and flop color of solid and metallic finishes. This is important when a repaired panel must match the vehicle from several viewing angles.

The weak tinting effect is suited to small, controlled additions. It is best used when the required correction is subtle and the colorist needs to preserve the original formula balance.

When used with the compatible Ultra 9K waterborne system, U9130 can support formula adjustment, spray-panel comparison and repair color development.

• Automotive body shop color formulation
• Collision repair and spot-repair color matching
• Dealership and 4S body shop refinishing
• Automotive paint mixing stores and distributor laboratories
• Blue, violet and cool-grey color correction
• Solid and metallic color adjustment
• Spray-out card and sample-panel testing
• Professional refinishing training and color demonstration

U9130 helps technicians make small blue-direction corrections before applying the repair color. Testing both face and flop can improve the decision-making process for localized repairs and blends.

The colorant supports a systematic approach to OEM-style color matching, particularly where a color looks acceptable from one angle but too warm from another.

The 1 L format and carton packaging are convenient for professional stock management and supply to workshops that use waterborne automotive refinish systems.

U9130 can be used for controlled demonstrations of hue direction, face/flop behavior and incremental color adjustment on spray-out panels.

1. Confirm the color formula: Identify the target color and determine whether a blue-violet correction is required.
2. Check system compatibility: Use U9130 only within the compatible Ultra 9K waterborne mixing system and follow the applicable technical documentation.
3. Start with a small addition: Because the tinting effect is described as weak, make controlled incremental additions rather than changing the formula aggressively.
4. Mix thoroughly: Ensure the colorant is evenly incorporated into the formula before spraying a test panel.
5. Prepare a spray-out card: Apply the mixed color using the recommended system process and allow it to dry as required.
6. Evaluate face and flop: Compare the spray-out panel under suitable lighting from direct and oblique angles.
7. Fine-tune if required: Adjust gradually until the color direction is acceptable. Excessive addition may make the color too blue or too cool.
8. Apply the repair system: Once approved, proceed with the compatible basecoat and clearcoat process according to the system instructions.

1. What is Sherwin-Williams U9130 used for?

U9130 is a waterborne HS Violet colorant used in the Ultra 9K automotive refinish mixing system for controlled blue-violet color correction.

2. Does U9130 work with solid colors?

Yes. It is intended to provide a blue cast in solid colors when used according to the compatible Ultra 9K formula and system process.

3. Can U9130 be used in metallic colors?

Yes. The supplied functional description covers solid and metallic colors on both the face and flop. A spray-out test should be completed before production application.

4. Is U9130 a strong violet toner?

Its stated tinting effect is relatively weak. It is more appropriate for gradual fine correction than for rapidly changing a color.

5. Will U9130 make a color bluer?

It is designed to add a blue direction to the color. Over-addition may make the final color appear too blue or too cool, so incremental dosing is recommended.

6. Can U9130 be sprayed directly onto a vehicle?

It is a color-mixing component, not a standalone ready-to-spray topcoat. It should be mixed and applied according to the compatible Ultra 9K system instructions.

7. How should the color be checked after adding U9130?

Prepare a spray-out panel and evaluate it under suitable lighting from both direct and angled viewing positions to check face and flop.

8. What is the package size?

U9130 is commonly supplied in a 1 L can, packed 3 cans per carton. The carton size is 37.8 × 13 × 15.5 cm.
