3166 vs 3482X vs 3307X is first a system-boundary decision, then a surface-test decision. CHLUMIFE® 3482X is a water-only, high-solids slip/anti-sticking route. CHLUMIFE® 3307X is a UV/solvent scratch-and-abrasion route with explicit recoat priority. CHLUMIFE® 3166 spans UV, solvent and water systems, but its pinhole, whitening and foam-stabilization warnings prevent it from being a risk-free default.
Slip, blocking, scratch and abrasion are different endpoints. Approve the product that passes the required finished-film tests and downstream print, laminate or recoat operations—not the product with the longest benefit list.
3166/3482X/3307X decision map
| System and dominant failure | First route | Mandatory gate |
|---|---|---|
| Waterborne film needs lower friction or anti-sticking | 3482X | Staged water dilution, freeze/pinhole and alcohol restrictions |
| UV or solvent film needs scratch/abrasion improvement and must recoat | 3307X | Specified 12.5% solvent predilution and recoat test |
| Broad surface balance is needed across system types | 3166 conditional screen | Pinhole, whitening, foam and downstream-adhesion checks |
| Failure is caused by incomplete cure, contamination or excessive film build | Correct process first | No additive approval until the blank is stable |
| Produto | Published system/data | Supplier guidance | Key risk |
|---|---|---|---|
| 3482X | Water only; 80±2% solids; nonionic; 3482X contains thickener | 0.05–1% total; dilute gradually with water | No alcohol; protect from freezing; diluted material should not be stored; pinhole risk |
| 3307X | UV/solvent only; 100% active; scratch/abrasion, leveling and recoat priority | 0.1–1% total; dilute to 12.5% with specified solvent blend | Not waterborne; confirm exact dilution instruction and recoat performance |
| 3166 | UV/solvent/water; 100% active; 0.05–1% total | Any-stage addition; optional suitable-solvent dilution | May cause pinholes, whitening or foam stabilization |
Start by naming the endpoint
Coefficient of friction describes resistance to sliding. Blocking is adhesion between contacting coated surfaces under pressure, time and temperature. Scratch is localized damage from a pointed contact; abrasion is cumulative wear. A product can improve one and worsen another.
Define the substrate, coating or ink chemistry, cure, film thickness, conditioning and downstream step before selecting a metric. Do not compare a waterborne package film with a rigid solvent-coated panel under unrelated methods.
Use 3482X inside its waterborne boundary
3482X is an ultra-high-molecular-weight polysiloxane pre-emulsion with 80±2% solids. The page supports waterborne coatings and inks, lower coefficient of friction, anti-sticking, slip feel and abrasion resistance. It is not approved on the page for UV or solvent systems.
Dilute with small water additions in multiple batches before incorporation. Do not mix with alcohol solvents, protect from freezing and do not store the diluted solution for extended periods. Include a blank and inspect pinholes at every level.
Use 3307X for UV/solvent durability with recoat
3307X is 100% active and designed to improve scratch and abrasion resistance after film formation while supporting leveling, smoothness and gloss. The page explicitly prioritizes recoatability. That makes it the more direct route when a cured UV or solvent film marks too easily and a later coat must still adhere.
The public instruction says to dilute it to 12.5% with a xylene/ethylene-glycol-monophenyl-ether blend listed as 7/2. Confirm the current TDS and exact ratio before preparation. Keep solvent contribution equal across the blank and candidates.
Use 3166 as a conditional broad-balance screen
3166 supports dry feel, surface-tension reduction, wettability, smoothness, scratch resistance, anti-blocking, leveling and gloss across all three system types. The same page warns of pinholes, whitening and foam stabilization and recommends considering a defoamer during formulation testing.
Those warnings matter most in waterborne or air-sensitive formulations. Do not add a second defoamer automatically; first test 3166 alone, identify whether air is present, then validate any combination and addition order.
Run separate slip, block, scratch and abrasion tests
ASTM D1894 measures static and kinetic coefficients of friction of plastic film or sheeting and notes that results are empirical and process-sensitive. ASTM D4060 evaluates abrasion resistance of organic coatings on plane rigid surfaces with a Taber abraser.
Neither method is a universal substitute for the customer’s substrate or converting line. Define wheel/load/cycles for abrasion, stylus/load for scratch, pressure/temperature/dwell for blocking, and contact pair/speed/conditioning for friction. Report initial and aged results.
Protect cure and downstream adhesion
- Confirm the blank reaches target cure before ranking additives.
- Apply equal dry-film thickness and condition every specimen identically.
- Measure gloss/haze, friction, blocking, scratch and abrasion separately.
- Run overprint, laminate, heat-seal or recoat tests at minimum and extended intervals.
- Age the liquid formulation and finished film, then repeat critical tests.
Include the low and high ends of the production cure window. Under-cure can make every candidate appear softer or more blocking, while over-cure may change friction, embrittlement and recoat response. Preserve failed panels so the damage mode—not only a single number—can be compared.
Request a system-and-test match
Send system type, resin, substrate, solids, cure, film thickness, current additives, failure mode, target COF, block conditions, scratch/abrasion method, gloss, recoat or conversion requirements and storage window. Ask Longchang Chemical to select between 3166, 3482X and 3307X from the required endpoint.
