Xiangrun New Materials – Waterborne Acrylic Emulsion & PU Resin Manufacturer Additives are 3% of your formulation cost and 90% of your troubleshooting time. Cratering, foam marks, poor color acceptance, sagging — each usually traces back to one additive choice. Xiangrun supplies the full additive toolbox for waterborne systems: imported originals and our own equivalents, with dosage guidance for your specific system.
The Waterborne Additive Toolbox
| Problem to solve | Recommended grades | Notes |
|---|---|---|
| Rheology / sag control | SN-612NC, UH-752, X-408 PU thickeners; HEC for open time | Newtonian vs shear-thinning balance per application method |
| Foam in production & application | SE-47 (Wacker), NXZ, T-4201A, DX-65 | Match defoamer to gloss level to avoid cratering |
| Substrate wetting & pigment dispersion | Surfynol 104E / 420 (Evonik), SAS-60 / SF-75 (Clariant), X-607, 5027 | Dynamic wetting for spray; dispersant demand by pigment type |
| Color acceptance in tinting systems | X-465 wetting & dispersing agent + compatible thickener pair | Prevents rub-out shift in POS tinting |
If you tell us the system (gloss level, PVC, application method) we will recommend a combination rather than a single product — additives interact, and we test them together.
Why Formulators Buy From Xiangrun
- Originals and equivalents under one roof: we distribute imported grades from ADEKA, Asahi Kasei, Clariant, Wacker, Croda, Evonik and PUCORE — and manufacture our own X-series / L-series equivalents when you need the same performance at a better cost.
- Free samples, freight collect: tell us your system and benchmark — the sample is free, shipped collect on your DHL/FedEx account, and most reach Europe within a week.
- Technical answers, not sales talk: our lab replies with starting-point dosages and compatibility notes for your specific formulation.
- Consistent supply: batch-to-batch COA, flexible MOQ from one drum, and export documentation handled for you.
Frequently Asked Questions
How do I choose between a mineral-oil and silicone defoamer?
By gloss and recoatability: mineral-oil types are economical for matt and semi-gloss; silicone types like SE-47 give stronger knockdown in high-gloss and spray systems but must be dosed carefully to avoid craters. We recommend based on your gloss target and send both for A/B testing.
Can your thickeners replace the ones we import at lower cost?
Often. SN-612NC and UH-752 are direct working equivalents to common Japanese and European PU thickeners. Send your current grade and dosage – we will propose the swap and free samples to verify rheology curves.
What dosage should we start with?
Every sample shipment includes a starting-point dosage sheet for your system type. Typical ranges: PU thickener 0.3-1.5%, defoamer 0.1-0.5%, wetting agent 0.2-0.8% on total formulation.
Do you supply small quantities for lab work?
Yes – free lab samples first, then commercial supply from single-drum quantities, so your pilot line can validate before scaling.
