No price on this page. The grade is quoted against structure, fill and volume — a number without those details would be a guess.
In short: Polyurethane resin for inks and coatings where the printed film passes through a heat-seal or hot-fill step. It is supplied by Zhongshan Baiton Coating Co., Ltd. in Zhongshan, Guangdong, China, with a technical data sheet covering solids, viscosity, mix ratio, pot life and cure schedule, plus a certificate of analysis for the batch shipped.
HY-PU30C is the grade in the range specified for high-temperature resistance. It is used where the printed or coated film has to keep its adhesion, gloss and strength through heat sealing, hot fill or a drying stage that would soften a standard PU binder.
Where it is considered
- Heat-seal lacquers and coatings on flexible packaging.
- Inks on structures that pass through a hot tunnel after printing.
- Applications where a standard PU resin has shown blocking, softening or loss of adhesion at temperature.
What decides whether it fits
Heat resistance is only one property. The resin also has to disperse in the intended solvent, carry the pigment loading the ink needs, and adhere to the treated substrate. Those four requirements are usually what the trial is testing, so the enquiry should state the substrate, the solvent system, the pigment and the temperature the print will see.

Questions about HY-PU30C
Which structure is this grade used on?
Grade selection is made against the structure and the fill. Send the film combination and the process conditions and the correct grade is confirmed in writing before the sample ships.
Is a data sheet available?
Yes — solids, viscosity, mix ratio, pot life and cure schedule are issued on the technical data sheet for this code, together with the certificate of analysis for the batch supplied.
Can this grade be trialled before a full order?
Yes. The sample is sized for a trial on the production line, and the trial should be checked for bond strength after the full cure rather than immediately.
