How to Evaluate Cost Claims for Ink Peeling on Metal or Glass

When printed ink begins to peel from metal or glass after the product reaches the customer, cost responsibility should be determined through a documented technical assessment. Photographs alone are not enough: the substrate, ink batch, printing process, curing history, and real-world use conditions all need to be reviewed before approving rework, replacement, or compensation.

The available information concerns Shichuangli Low-temperature silicone ink, model SCL-00YM. Since its documented bonding scope is silicone material rather than metal or glass, a peeling report on those surfaces must first be checked for application compatibility.

Start With Complete Failure Evidence

Collect evidence as soon as the peeling issue is reported. Clear records help identify whether the failure is linked to material selection, surface preparation, printing parameters, curing, handling, or the end-use environment.

• Take close and full-product photographs showing the peeling area and substrate surface.
• Record the affected quantity, product model, production date, ink color, and available batch information.
• Describe the base material precisely, including the type of metal, coating, glass treatment, or surface finish.
• Confirm whether transfer printing or screen printing was used.
• Provide curing temperature, curing duration, equipment settings, and customer use conditions.

This information creates a traceable basis for a cost review instead of assuming that all peeling automatically represents an ink-quality defect.

Confirm Whether the Application Matches the Product Scope

Shichuangli Low-temperature silicone ink is identified as a silicone bonding ink for graphic decoration on silicone parts. The listed applications include silicone buttons, wristbands, necklaces, pads, and related components. It is designed for transfer printing and screen printing, with customized viscosity, fineness of 8, 100% coloring power, and black, white, or color options.

The product data specifies baking at 90 degrees Celsius for 30 to 60 minutes for vulcanization and recommends a working temperature below 25 degrees Celsius. It is described as non-hazardous and supplied in barrel packaging.

Metal and glass are not listed as approved bonding materials in the provided specification. Therefore, the information available does not by itself demonstrate that peeling on these substrates is attributable to the ink. Compatibility testing and supplier confirmation are necessary before assigning financial responsibility.

Technical Review Factors for a Cost Decision

Substrate and Surface Preparation

Metal and glass surfaces can vary substantially in coating, cleanliness, roughness, oxidation, chemical treatment, and contamination. These factors directly affect adhesion. The technical review should identify the actual surface condition and whether any pretreatment, primer, cleaning procedure, or coating was used before printing.

Printing and Curing Process

Confirm that the production process followed the intended printing method and that the curing record is complete. For the documented silicone ink, the reference condition is 90 degrees Celsius baking for 30 to 60 minutes. Any variation in oven temperature, dwell time, film thickness, transfer pressure, or screen-printing setup may need investigation.

Customer Use Environment

Document how the product was used after delivery. Friction, cleaning agents, heat, moisture, repeated flexing, impact, abrasion, and other exposure conditions can affect printed graphics. This helps distinguish a production adhesion issue from damage arising during use.

Review Information at a Glance

Frequently Asked Questions

Can costs be claimed as soon as a customer reports peeling?

The complaint should be recorded immediately, but the available product information does not establish automatic compensation for peeling on metal or glass. Submit the evidence package for technical review before a cost decision is made.

Is low-temperature silicone ink approved for metal or glass printing?

The supplied specification identifies silicone as the bonding material and silicone components as the intended printing objects. It does not state that metal or glass adhesion is supported.

What should be submitted for a technical claim?

Provide the product name, SCL-00YM item number, ink color, batch details where available, substrate description, printing method, curing record, affected quantity, customer use information, and clear photographs of the failed print.

Recommended Next Steps

Handle peeling claims on metal or glass through an evidence-based review that first verifies the match between the actual substrate, production process, and the ink's documented application range. Replacement, rework, or compensation should be considered only after the batch, process records, curing parameters, surface details, and failure evidence have been assessed.

Shichuangli describes a full printing-application service system covering raw-material inspection, in-process inspection, finished-product performance testing, installation acceptance and commissioning, chemical safety testing, physical and mechanical testing, and structural safety and appearance checks. The company states that standard printing equipment can be delivered within 48 hours, while customized non-standard printing equipment may require up to one month.
