Plan the assortment around different application needs
The ZUOTONG reducer range separates general-purpose use, stronger solvency and extra-slow application requirements into three named products. ZK103, ZK301 and ZK300TM are designed to accompany compatible ZUOTONG coatings, adjusting spray viscosity and supporting workability and film flow.
For distributors and workshop purchasing teams, the useful distinction is not simply good, better and best. Each model has a different stated role. A supply proposal should identify the grade, pack format, coating pairings and technical instructions that go with the order.

Confirm weight basis and outer packing in the quotation. The source does not establish whether these are net weights; they must not be presented as gross shipping weights. Carton dimensions and pallet quantities also need confirmation.
Do not extend the 5 L offering to ZK103: only its 4 L format is verified in the extracted text.
Where the range can support trade customers
A coatings distributor with varied workshop accounts
Create a confirmed pairing list for the ZUOTONG coatings being supplied. Position ZK103, ZK301 and ZK300TM by function so sales staff do not substitute grades based solely on stock availability.
A multi-location repair group
Combine central purchasing with local application information. Standardise model identity and documentation while allowing grade selection to follow the actual coating and conditions at each location.
A supplier serving customers with seasonal hot-weather work
Plan the extra-slow offering against customer demand and approved application guidance. A seasonal purchase forecast is useful, but it does not replace the technician's grade-selection decision.
These are representative supply scenarios, not verified customer case studies or forecasts of sales growth.
Why the range is straightforward to specify
Distinct model identities. The three names separate different selection requirements instead of describing every application as universal.
A documented primer recommendation. The source recommends the high-performance grade for primer spraying, giving buyers a specific point to confirm with their primer system.
Multiple listed formats where available. ZK301 and ZK300TM have 4 L and 5 L references; ZK103 has a 4 L reference. Packing details remain model-specific.
A stated stock-life condition. The unopened room-temperature storage period is two years. Keep that condition attached to the shelf-life entry.
A clear application function. The reducers lower spray viscosity and assist workability and levelling in the intended compatible systems. No quantified finish, labour or consumption improvement is claimed here.
Understand the system being supplied
These products are thinners for compatible ZUOTONG coatings, not complete paint systems or substitutes for hardener. The coating provides its specified layer; any required hardener follows that coating's activation instructions; the selected reducer is added only as directed.
The source identifies relative solvency for ZK301 and an extra-slow role for ZK300TM. It does not disclose full solvent composition. Obtain separate current SDS documents for the selected products rather than assigning the same formula, CAS number or transport classification across the range.

How to qualify the range for repeat orders
Collect the actual coating list
Record the exact ZUOTONG products your customers use, including any hardener. Request approved reducer pairings and addition instructions for each coating.
Define the application conditions
Ask customers about working conditions and job sizes. Do not replace missing technical temperature bands with guessed winter, summer or tropical-climate thresholds.
Validate the proposed combination
Use the coating's approved mixing and spray method in a representative trial. Record the selected grade, addition rate and conditions. Assess the completed coating process before publishing a performance claim.
Separate routine instructions from contingencies
The source's ZF155 note concerns a particular hot-condition situation when ZK300TM is unavailable. Obtain the exact formulation, dosage and procedure from the supplier before including it in a customer instruction sheet.
Keep orders and labels specific
Use the model, pack format and agreed packing details on repeat orders. Retain current technical and safety documents and review proposed product substitutions before accepting them.
Stock handling and dispatch details
The supplier instructs users to close containers after dispensing to limit evaporation. Store in a ventilated, dry location and observe the stated fire precautions. The two-year statement applies to unopened product at room temperature, not to material left open, repacked or stored under unspecified conditions.
Before arranging transport, obtain the applicable SDS, outer dimensions, gross weights and shipment information for each model and format. The listed litre and kilogram figures are not a complete logistics specification.
Wholesale supply and private-label briefs
For wholesale pricing, send a model-by-model quantity schedule, pack preference and destination. Request current availability, MOQ, delivery terms and packaging confirmation with the offer.
For OEM enquiries, provide brand ownership, target market, label language, artwork needs and volume forecast. Private labelling, packaging changes and custom formulation are not confirmed in the extracted source. Ask the supplier to define the available scope before promising customisation to a customer.

Distributor and purchasing FAQ
Is the range a simple good/better/best hierarchy?
No. It separates general-purpose, higher-solvency and extra-slow requirements. The correct grade depends on the approved coating process.
Which models have a listed 5 L format?
ZK301 and ZK300TM. A 5 L ZK103 format is not established by the extracted source.
Can the listed kilogram figures be used for freight quotations?
Not without confirmation. The weight basis and complete gross packing weights are not verified.
Are all three products supplied in identical cartons?
Six-can configurations are listed with the 4 L entries, but carton dimensions and the 5 L outer-pack quantities are not provided. Confirm each ordered configuration.
What does the two-year storage statement cover?
Unopened product stored at room temperature. Follow the current documents for storage and handling, and do not extend the claim to opened or repacked material.
Is private-label production already confirmed?
No model-specific OEM commitment is established in the available information. Submit a brief for supplier review.
Can one SDS be used for every grade?
The source does not establish identical composition. Request the current document applicable to each model being purchased.
What is needed for a complete quotation?
Provide the model, size, quantity, destination and application requirements. Ask for pricing, packing, technical documents and delivery terms in the same response.
