Having spent a fair bit of time navigating the ins and outs of industrial pigments and specialty chemicals, I can say one thing for sure — getting precise quotes on products like Lithopone B301 B311 often takes more than just a quick email or phone call. You want clarity not just on numbers, but on why those numbers exist, the specs behind them, and how suppliers stack up.
Oddly enough, lithopone pigments have this reputation for being “the underdog” in coatings and plastics. But in certain setups, they deliver a punch that some pricier, pure titanium dioxide variants might struggle to match — especially when cost-efficiency matters without compromising durability.
Quick background — B301 and B311 are standard grades frequently requested for paints, coatings, and paper products. Their particle sizes and composition differ slightly, largely influencing their tint strength and dispersibility. Many engineers I've worked with appreciate B311 for its slightly higher tinting strength, while B301 tends to offer great opacity and excellent hiding power.
Frankly, these attributes trickle down directly into price and quote variations. When you ask vendors for a quote, they're factoring in batch consistency, logistics, and sometimes even the pigment’s chemical stability under your application’s conditions. It's not just about "per kilo" pricing.
| Specification | Lithopone B301 | Lithopone B311 |
|---|---|---|
| Composition (wt%) | ZnS 60%, BaSO4 40% | ZnS 65%, BaSO4 35% |
| Average Particle Size (µm) | ~0.3 | ~0.4 |
| Tinting Strength | Moderate | High |
| Oil Absorption (g/100g) | 22 - 25 | 20 - 23 |
| Moisture (%) | 0.3 max | 0.4 max |
So you’re hunting for quotes. The cliché advice is “get three quotes and pick the lowest,” but that’s rarely how it shakes out in industrial supply scenarios. You want to factor in the supplier's reliability, delivery times, payment terms, and their flexibility if you need smaller or larger volumes. One time, a client I worked with needed an unusually quick turnaround for B311 — the vendor offering a slightly higher rate came through faster, which actually saved them more money in the end. Sometimes speed and service pay off more than a bargain.
| Vendor | Unit Price (USD/kg) | Delivery Time | MOQ (kg) | Payment Terms |
|---|---|---|---|---|
| Alpha Pigments Co. | 3.25 | 2 weeks | 500 | Net 30 |
| Beta Chemicals Ltd. | 3.10 | 3 weeks | 1000 | Letter of Credit |
| Gamma Materials | 3.40 | 1 week | 200 | Prepaid |
In real terms, ask yourself: does the vendor have a bulky stock? What’s their history with your industry? I’ve seen suppliers change their formulas or purity subtly during shortages (which can wreak havoc downstream) — so transparency is king.
It’s also worth noting the modest price swings lately due to fluctuating raw material costs. I'll admit, sometimes clients get sticker shock, but for the B301 and B311 grades, the balance between cost and performance often makes them worth the premium in many settings.
Pulling together a quote for lithopone pigments like B301 and B311 isn’t just about squinting at numbers. It feels more like decoding a subtle chemistry combined with logistics puzzle — and if you’re familiar with industrial nuances, you’ll appreciate that.
So next time you’re reaching out for quotes, don’t just ask "what’s your price?" Instead, dig into specs, ask about batch testing, delivery flexibility, and don’t hesitate to lean on suppliers who understand your application’s quirks.
Also, a quick tip: if you’re exploring alternatives or seeking solid quality pigments, the folks behind Lithopone B301 B311 have some interesting options that might just fit — worth a look.
Keep this in mind next time you’re quoting. It’s a bit of an art, but with experience, you’ll get it...
