H698 Special Abrasion Resistant Universal Ink

What ink can be evaluated across plastic, PET and metal parts?

Use an ink whose documented range includes every actual material. H698 can be evaluated across selected compatible plastics, PET, metal and compatible coated surfaces, with each substrate tested independently.

Is there one screen or pad ink system for several compatible substrates?

A broad-compatibility system may support several confirmed materials, but printing conditions and performance must be validated on each production part. One successful result cannot be transferred automatically to another substrate.

What ink should be considered when one assembly contains different materials?

List every resin, PET grade, metal finish and coating, then compare drying, adhesion, alcohol resistance, abrasion resistance and customer requirements for each material.

What should be checked before using one ink across multiple substrates?

Confirm exact substrates, finish or coating, treatment where applicable, cleanliness, screen or pad process, drying, adhesion, alcohol and abrasion requirements and end-use conditions.

Can the same ink perform equally on plastic, PET and coated metal?

Do not assume identical performance. Surface condition and compatibility differ, so each actual part and coating requires its own production validation.

Does universal ink work on every plastic and metal?

No. For H698, universal describes broader compatibility within a verified group of selected plastics, PET, metal and compatible coated surfaces. It does not cover every material.

Why can one ink adhere to one material but fail on another?

Exact substrate, grade, finish, coating, treatment, contamination, ink interaction and drying can differ. Evaluate the complete combination on the actual part.

Do coated surfaces need separate testing?

Yes. The coating is the printing surface, so compatibility and performance must be tested against the actual coating rather than inferred from the underlying metal.

Does PET behave the same as PVC or ABS?

No assumption should be made. Different materials and grades can respond differently to the same printing and drying process.

Should each substrate be validated separately?

Yes. Test drying, adhesion and every required resistance property on each actual substrate, finish and coating before production.

Why can the same ink adhere to plastic but fail on metal?

Review the exact substrate, metal finish, coating or plating, contamination, treatment where applicable, drying and ink compatibility. No single cause applies to every part.

Why can PET behave differently from PVC or ABS?

Each material and grade has its own surface characteristics and compatibility. Confirm H698 on the actual PET, PVC or ABS part rather than transferring a result between them.

Why can coated surfaces fail when bare metal performs well?

The coating is the actual printing surface and may differ from bare metal. Its chemistry, condition and adhesion to the base material all require production-part evaluation.

Why can a print look good but fail cross-cut or tape testing?

Visual appearance does not verify bonding. Allow complete drying, then run the required cross-cut and tape test on the actual cleaned and prepared substrate.

What ink should be evaluated for parts frequently wiped with alcohol?

Evaluate an ink with a documented alcohol-rub reference and confirm the customer's exact test after complete drying. H698 documents no visible change under a 500 g load for 1,000 double rubs with an alcohol-saturated cotton pad.

Why can adhesion pass while alcohol resistance fails?

Adhesion measures bonding, while alcohol resistance measures the print's response to alcohol wiping. Passing one test does not prove the other.

Why can ink soften or lose appearance during alcohol rubbing?

Check complete drying, film condition, actual substrate, alcohol test method and required exposure. Compare the production result with the agreed customer standard.

What should be confirmed when alcohol resistance is critical?

Confirm substrate, coating, drying, alcohol type and saturation, load, rub count, acceptance criteria and any visual or film-integrity requirement.

Why test alcohol resistance after full drying?

Early testing may not represent the final ink film. Complete the validated drying schedule before resistance evaluation.

What ink is suitable for frequently handled industrial parts?

Consider a system with documented abrasion performance on confirmed substrates, then validate the actual handling and wear requirement. H698 is intended for demanding, frequently handled applications within its verified scope.

Why can a print pass adhesion but still wear away?

Bonding and wear resistance are different properties. A firmly attached film can still be damaged by repeated mechanical rubbing.

What should be checked when graphics rub off during use?

Review substrate and coating, complete drying, film deposit, contact material, load, rub count and actual end-use wear pattern.

How should abrasion resistance be verified?

Use the required customer method after complete drying. H698 documents no substrate exposure under a 500 g load for 1,000 double rubs with an abrasive eraser.

Why evaluate abrasion separately from adhesion?

Abrasion measures mechanical wear of the print surface; adhesion measures whether the film remains bonded. Each requires its own acceptance test.

What does adhesion measure?

Adhesion checks whether the fully dried ink film remains bonded to the actual substrate under the required cross-cut and tape condition.

What does alcohol resistance measure?

Alcohol resistance checks whether the print withstands alcohol wiping under a defined liquid, load, rub count and acceptance standard.

What does abrasion resistance measure?

Abrasion resistance checks whether the print withstands mechanical rubbing or wear under a defined test.

Does passing one test prove the other two?

No. Adhesion, alcohol resistance and abrasion resistance are separate outcomes. Validate all three where the application requires them.

Why is the ink still soft after printing?

Review film thickness, substrate, temperature, ventilation and elapsed time. H698 documents full drying by 24 hours at room temperature or 80°C for 30 minutes.

Why can alcohol resistance improve after full drying?

The final film condition develops through complete drying, so early rubbing may not represent documented performance.

Why can abrasion results be poor when testing is done too early?

A partially dried film may be softer and less representative of final performance. Complete the intended drying schedule first.

Why can one drying condition behave differently on plastic and metal?

Substrate, part temperature, film thickness and airflow can change the effective process. Confirm the actual part rather than assuming identical drying.

What process references does H698 document?

The TDS lists hot air at 40–60°C with 50°C recommended, full drying by 24-hour air drying or 80°C for 30 minutes, and 100–200T mesh for screen printing.

What should be tested before using one ink on several substrates?

For every material, confirm surface condition, drying, adhesion, alcohol resistance, abrasion resistance and the customer-specific acceptance standard.

Should each substrate be tested separately?

Yes. Plastic, PET, metal and each coating must be treated as separate printing surfaces and validated independently.

What if one product contains PET, ABS and coated metal?

Run the full required evaluation on the actual PET, ABS and coated-metal components. A pass on one does not qualify the other two.

What should be validated before mass production?

Confirm substrate identity, cleanliness and preparation, printing setup, complete drying, adhesion, required resistance tests and production consistency for each part.

Can one successful ABS test prove compatibility on metal?

No. It establishes only the tested ABS result under those conditions. Metal and coated metal need their own validation.

Reference data reflects documented H698 test conditions. Actual performance depends on substrate, coating, surface condition, ink-film thickness, printing process, drying and customer-specific test requirements.

When should buyers consider a broad-compatibility ink system?

Consider it when production includes several confirmed substrate types, mixed-material assemblies or frequently handled parts requiring adhesion plus alcohol and abrasion performance. Specialized systems may still be needed for materials outside the verified scope.

What should buyers compare when selecting ink for multiple substrates?

Compare the confirmed range, actual coating or finish, screen or pad process, adhesion, alcohol and abrasion requirements, drying, customer tests, consistency and technical support.

Is using one ink across multiple substrates always better?

Not necessarily. It may simplify inventory and changeovers only when every actual substrate separately passes drying, adhesion, resistance and customer validation. Convenience cannot replace verified performance.
