STANDARD OPERATION
General PU Doming Mixing and Dispensing Process
01Confirm the Selected 3:1 or 1:1 Formula
02Accurately Measure Part A and Part B
03Mix Thoroughly and Avoid Local Ratio Errors
04Dispense Onto the Prepared Label or Product

Exact working time, curing conditions and production settings vary by formula. Follow the corresponding product TDS and confirm through sample testing.
PRODUCT NOTES
PU Processing Requires Accurate Mixing and Clean Conditions
Use the exact formula-specific weight ratio.
Keep Part A and Part B sealed and uncontaminated.
Avoid moisture entering the components or mixed resin.
Mix material from the container walls and bottom thoroughly.
Temperature affects viscosity and working time.
Confirm substrate, ink and coating compatibility before production.

What is the main difference between 3:1 and 1:1 PU doming resin?
The 3:1 formula is positioned around balanced outdoor cost-performance and longer working-time direction, while the 1:1 formula is positioned around easier equal-ratio mixing and premium long-term outdoor requirements.
Which formula is better for cost-controlled mass production?
The 3:1 PU doming resin is generally the starting option when production cost, repeat orders and longer working-time direction are higher priorities.
Which formula is intended for premium outdoor orders?
The 1:1 clear PU doming resin is positioned for premium outdoor dimensional products, easier mixing and stronger long-term anti-yellowing positioning.
Does the 1:1 formula always perform better than the 3:1 formula?
No. The 3:1 product may be more appropriate when longer working time and production cost are higher priorities. The 1:1 product is positioned for easier mixing and premium long-term outdoor requirements.
Can both products be used with automatic dispensing machines?
Both formulas may be evaluated for machine dispensing. Final machine compatibility depends on metering ratio control, viscosity, equipment configuration and production parameters.
Can these products be used for indoor labels?
They may be evaluated for indoor labels, but PU is primarily presented here for flexible outdoor doming requirements. Indoor cost-focused applications may also review epoxy doming resin.
Are the 2-year and 5-year claims guarantees?
No unconditional guarantee should be stated. These values describe product anti-yellowing positioning under defined conditions. Actual results depend on UV exposure, environment, substrate and production quality.
Can I request both formulas for testing?
Yes. Buyers can request 3:1, 1:1 or both formulas for comparison under actual production and application conditions.
Which substrates can be used?
Selected paper, PVC, PET, acrylic and other printed label substrates may be evaluated after compatibility testing. Universal adhesion is not claimed.
Do you support private-label packaging?
Private-label packaging can be discussed based on selected formula, target market, estimated quantity and repeat supply requirements.
