AG-D9000 vs 3000 vs 3170<\/strong> is an evidence and system comparison, not a universal easy-clean ranking. AG-D9000 publishes hydroxyl data and a solvent-side 2K\/bake route. 3000 is documented for UV and solvent systems. 3170 spans those systems and allows aqueous use only after hydrophilic-solvent predilution. Prove cleanability, cure and adhesion separately.<\/p>\n

Use AG-D9000 only with stoichiometric evidence<\/h2>\n

AG-D9000\u2019s OH value is the strongest functional evidence among the three, but it does not supply a complete formulation calculation. For a 2K route, obtain exact batch OH, resin OH, isocyanate equivalent, solids and target NCO\/OH. The page recommends high-OH acrylic resin and longer bake time for low-temperature two-pack work. Record pot life and cure.<\/p>\n

Keep 3000 out of waterborne systems<\/h2>\n

The 3000 page explicitly says it is not suitable for water-based systems. Its 0.5\u20135% range is much wider and higher than 3170\u2019s, so an equal-dose comparison is inappropriate. Test UV or solvent compatibility, cure, surface migration and recoat. Do not call it reactive without functional-group or equivalent-weight data.<\/p>\n

Treat 3170 aqueous use as conditional<\/h2>\n

3170 permits aqueous use only after predilution with a hydrophilic solvent. Record solvent identity, ratio, order, mixing and VOC effect. The public page gives no active-content value, so do not normalize it against 100%-active grades without current TDS data. Conditional entry is not proof of long-term waterborne stability.<\/p>\n

Define easy-clean performance<\/h2>\n

Specify marker, graffiti medium, dwell, cleaning agent, cloth, load, strokes and acceptance. Measure gloss, color, stain, swelling and adhesion before and after cleaning. Hydrophobicity or a higher contact angle can support a hypothesis but does not independently prove stain release or repeated-clean durability.<\/p>\n

Measure appearance consistently<\/h2>\n

ASTM D523<\/a> covers specular gloss. Fix geometry, film build and cure age. A gloss increase or loss is not itself easy-clean performance; record it as a surface-change guardrail.<\/p>\n

Check adhesion and abrasion<\/h2>\n

ASTM D3359<\/a> provides tape adhesion methods. Document failure location and method limits. ASTM D4060<\/a> covers Taber abrasion; report wheel, load, cycles, conditioning and film thickness. Cleaning and abrasion are different stresses.<\/p>\n

Approve cure and recoat<\/h2>\n

Measure cure at minimum, target and extended bake or UV conditions. For 2K systems, include early and late pot-life panels. Apply the intended next coat or adhesive at realistic intervals. A highly surface-active film can clean well yet fail at the next interface.<\/p>\n

Separate contact angle from service performance<\/h2>\n

AG-D9000\u2019s page mentions improved water contact angle, but contact angle depends on liquid, dwell, temperature, film condition and measurement method. Record advancing or static method as applicable and use the value only as supporting surface evidence. It cannot replace marker removal, repeated cleaning, stain, abrasion or recoating results.<\/p>\n

Run the easy-clean protocol after initial cure and again after heat, humidity or chemical aging. Surface migration may improve early results and then change during service. Photograph each panel under controlled lighting and record gloss and color change, not only whether the marker appears to disappear.<\/p>\n

Regole decisionali<\/h2>\n

Compare each grade only inside its eligible vehicle and approved process. Because dose ranges and active-content evidence differ, a single equal as-supplied level would confound product efficiency with concentration and compatibility. Start from the supplier-supported low dose, optimize viable candidates independently and retain the unchanged coating as the reference throughout aging and repeated cleaning cycles under controlled conditions.<\/p>\n
