快速回答： buyers should not treat AG-D9000, CHLUMIAG® 3000， 和 CHLUMIAG® 3170 as the same easy-clean additive. AG-D9000 should move up first when the project is clearly a 溶剂型涂料 and the buyer wants a direct route for 马克笔擦拭阻力, 阻滞阻力， 和 surface cleanability. CHLUMIAG® 3000 becomes the stronger first route when the team wants a reactive easy-clean and anti-graffiti route 为了 UV or solvent systems and does not need water-based compatibility. CHLUMIAG® 3170 belongs earlier when the buyer wants similar reactive easy-clean logic but also wants the option to enter an aqueous system after hydrophilic-solvent pre-dilution.
That is the useful buyer split. This page is narrower than the already-live anti-graffiti additive guide and the broader 3000 vs 3170 vs 5000 comparison. It is for coating teams who are already working near the solvent-side easy-clean branch and need to decide whether the first screen should start with a direct solvent-based marker-wipe route or with a 反应式易清洁路线.
为什么这项比较值得单独成页？
Longchang already has broader CHLUMICRYL® pages that explain anti-graffiti additives by system type and a comparison page that separates 3000, 3170, and 5000 mainly by UV, solvent, and water-based fit. That still leaves a narrower B2B decision unanswered: if the project is mainly solvent-side today, should the buyer start with AG-D9000, 3000, or 3170?
That question is distinct because these three routes do not win for the same reason:
- AG-D9000 wins when the buyer wants a direct solvent-based marker-wipe and cleanability route with practical low-temperature-bake guidance.
- 3000 wins when the buyer wants a 反应式易清洁路线 for UV or solvent systems without needing aqueous crossover.
- 3170 wins when the buyer still wants reactive anti-graffiti logic but may also need to bridge toward aqueous use later.
That is a cleaner page type than another broad anti-graffiti overview, because it helps buyers shorten the first sample round inside one commercially relevant branch.
What buyers are usually trying to fix in this branch
In practical easy-clean coating work, buyers often reach this branch when the coating has to do more than look smooth on day one. The real KPI is often one of these:
- 马克笔擦拭阻力 or easier stain release after writing and cleaning
- 阻滞阻力 and lower dirt pickup on the finished film
- hydrophobic and oleophobic surface behavior that supports easier maintenance
- a reactive route that stays more permanently fixed in the cured film instead of acting only like a temporary slip aid
- future formulation flexibility when the project may need to extend from solvent or UV toward an aqueous path
That general industry framing is conservative. Easy-clean and anti-graffiti programs are usually judged by final-surface maintenance behavior, not only by wet-stage application. The product-specific claims below stay tied to current Longchang-supported product pages.
快速对比表：哪条路线应该优先显示？
| 观察到的买家优先 | 最佳首选路线 | 为什么它应该排在第一位 | 主要观察点 |
|---|---|---|---|
| Direct solvent-based marker wiping, cleanability, blocking resistance, and hydrophobic or oleophobic surface behavior | AG-D9000 | Longchang explicitly supports marker-pen wiping resistance, blocking resistance, anti-graffiti, cleanability, and solvent-based use | For two-pack low-temperature baking, Longchang advises high-hydroxyl acrylic resin and longer bake time; varnish compatibility should be checked first |
| Reactive easy-clean and anti-graffiti route for UV or solvent systems, without needing water-based fit | CHLUMIAG® 3000 | The current Longchang route positions it around reactive easy-clean performance in UV and solvent systems and excludes water-based systems | Not suitable for water-based systems |
| Reactive easy-clean route that may also need aqueous-system entry after hydrophilic-solvent pre-dilution | CHLUMIAG® 3170 | Longchang gives it similar reactive easy-clean logic while allowing aqueous use after hydrophilic-solvent pre-dilution | Aqueous use is conditional and should not be treated as identical to a water-based-only emulsion route |
When AG-D9000 is the better first move
AG-D9000 should move to the front when the buyer wants the most direct solvent-based easy-clean route and the project is being judged by final-surface maintenance signals such as marker wiping, 阻滞阻力， 和 surface cleanability. Longchang’s current product page is unusually explicit here. It supports AG-D9000 as a 带羟基的聚二甲基硅氧烷 为了 溶剂型体系 and states that it can improve 表面防涂鸦和可清洁性, 水接触角, 阻滞阻力, wiping resistance from marker pen, 疏水性， 和 疏油性.
The same page also adds a practical process note that matters commercially: in a two-pack low-temperature-baking system, Longchang suggests using an 高羟值丙烯酸树脂 和 延长烘焙时间 to improve anti-graffiti performance. It also says the product should be diluted to 10% to 20% with xylene before addition and that varnish compatibility should be evaluated first.
- Best first-screen use: direct solvent-based marker-wipe and cleanability screening
- Dosage guidance: 0.5% to 3% of total formulation
- 主要优势： the page directly names the final-use signals buyers care about, including marker-pen wiping resistance
- Main caution: build the low-temperature-bake and varnish-compatibility notes into the first trial instead of leaving them for later
In short, AG-D9000 is the cleaner first move when the project is already solvent-side and the buyer wants a direct answer around marker wiping and easy cleaning, not just a broader anti-graffiti label.
When CHLUMIAG® 3000 is the better first move
3000 deserves earlier review when the buyer wants a 反应式易清洁路线 rather than the more direct solvent-side marker-wipe route. Longchang’s current anti-graffiti branch positions 3000 around a route where reactive groups bond into the resin system and support more durable hydrophobic, oleophobic, dust-reducing, washable， 和 不粘 behavior. The product page also places it in 紫外线系统 和 溶剂体系 while explicitly excluding 水基系统.
That makes 3000 the stronger first route when:
- the line is already committed to UV cure or solvent-based chemistry
- the team wants a reactive easy-clean and anti-graffiti benchmark instead of a more direct solvent-side special case
- the project does not need aqueous crossover in the first round
- the buyer wants one route that fits broader industrial or protective easy-clean design without forcing a water-based compromise
3000 is therefore not the same kind of choice as AG-D9000. It is more useful when the team wants a durable reactive route across UV or solvent easy-clean systems, not only a solvent-based marker-wipe route.
When CHLUMIAG® 3170 is the better first move
3170 becomes more useful when the buyer wants much of the same reactive easy-clean logic as 3000, but needs more room for future formulation movement. Longchang’s current product page supports 3170 for 紫外线系统 和 溶剂体系 and also says it can enter 用亲水溶剂预稀释后的水性体系. The recommended dosage is also lower, at 0.05% 至 1%.
That makes 3170 the better first route when:
- the project is solvent or UV today but may need to bridge toward aqueous testing
- the buyer still wants a reactive anti-graffiti and easy-clean route
- lower starting dosage flexibility matters in the first screen
- the team wants one route that can compare across more than one system family before locking the final resin path
The caution is important. 3170 is not a water-based-only route. Its aqueous entry depends on 亲水溶剂预稀释, so buyers should not treat it as interchangeable with a dedicated water-based emulsion route such as 5000.
买家在索取样品前应该如何选择
1. Start with whether the project is solving a direct solvent-side maintenance problem or a reactive surface-design problem
If the real target is marker wiping, cleanability, and blocking resistance in a solvent-based coating, AG-D9000 deserves much earlier attention. If the target is a broader 反应式易清洁路线 for UV or solvent systems, 3000 or 3170 usually make more sense.
2. Keep future formulation direction visible
3000 is cleaner when the project does not need aqueous crossover. 3170 becomes more defensible when the formulation team may need to move toward an aqueous path later without abandoning the reactive easy-clean branch entirely.
3. Do not ignore process notes
AG-D9000 brings direct commercial value, but it also brings practical process rules around xylene pre-dilution, low-temperature baking, and varnish compatibility. Those notes often decide whether the route is truly convenient in production.
4. Separate marker wiping from broad anti-graffiti branding
All three products live near the easy-clean branch, but AG-D9000 wins because the page directly names marker-pen wiping resistance. 3000 and 3170 win because they give a reactive easy-clean route with different system flexibility. That is a real selection split, not a wording nuance.
5. Keep the first round tight
对许多买家来说，最干净的第一轮是…… AG-D9000-led direct solvent route， 一 3000-led reactive UV or solvent route，以及一个 3170-led reactive crossover route. That usually teaches more than comparing too many nearby easy-clean additives at once.

常见问题
Which additive should I screen first if marker-pen wiping resistance is the main requirement?
Usually AG-D9000, because Longchang directly supports it around marker-pen wiping resistance, blocking resistance, hydrophobicity, oleophobicity, and cleanability in solvent-based systems.
When should 3000 move ahead of AG-D9000?
3000 should move ahead when the project is less about a direct solvent-side marker-wipe screen and more about a reactive easy-clean route for UV or solvent systems, especially when water-based fit is not needed.
When is 3170 a better first route than 3000?
3170 becomes the better first route when the buyer wants reactive easy-clean logic similar to 3000 but also wants the option to enter an aqueous system later through hydrophilic-solvent pre-dilution.
Are these three products interchangeable?
No. AG-D9000 is the more direct solvent-based marker-wipe and cleanability route, while 3000 and 3170 are better understood as reactive easy-clean routes with different system flexibility.
Need a faster easy-clean shortlist?
If your coating project is stuck between marker wiping, reactive anti-graffiti durability， 和 future aqueous crossover, stop treating every easy-clean additive as the same first move. Start by deciding whether the project needs a direct solvent-based route，一个 reactive UV or solvent route或者 reactive route that can later bridge toward aqueous use. That usually shows much faster whether AG-D9000, CHLUMIAG® 3000, or CHLUMIAG® 3170 deserves the first sample round.
