Every Transfer Is a Negotiation Between Ink and Fabric. The Powder Is the Mediator.
Direct-to-Film printing has quietly become the backbone of custom apparel manufacturing — the technology that puts logos on uniforms, designs on t-shirts, and branding on promotional merchandise at volumes that screen printing cannot economically match. The process is deceptively simple: print a design onto PET film, apply adhesive powder, cure with heat, and press onto fabric. But the difference between a transfer that survives 50 wash cycles and one that peels after three hangs on a single variable: the adhesive powder.
The Bond Catalyst is 1 kilogram of hot-melt polyamide powder engineered specifically for the DTF workflow. Its particle size distribution — tightly controlled between 80 and 200 microns — ensures uniform melting and consistent film formation across the entire printed surface. Too coarse, and the powder creates a gritty texture that compromises the transfer's hand feel. Too fine, and it clumps during application, leaving bald spots where ink bonds to nothing. The Bond Catalyst lands in the Goldilocks zone that professional print shops have spent years dialing in through trial and error.
Ink makes the image. Powder makes it permanent.
Key Features

Application Scenarios
The Bond Catalyst is purpose-built for the DTF (Direct-to-Film) printing workflow. Custom apparel shops — produce t-shirts, hoodies, and workwear with transfers that withstand industrial laundering. Promotional merchandise printers — run high-volume batches of branded giveaways with consistent adhesion across fabric types. Sports uniform manufacturers — DTF transfers on performance polyester that survive sweat, stretch, and repeated washing. Small-batch creators — the resealable packaging means the powder stays fresh between jobs; no waste from opened bags that absorb ambient moisture. Sublimation hybrid workflows — use as a bonding layer when combining DTF printing with sublimation base layers for complex multi-process designs.
Frequently Asked Questions
Q: What is the ideal powder application method?
A: For best results, apply powder immediately after printing while the ink is still wet. Use a powder shaker or automated powdering unit to distribute evenly, then shake off excess. The powder only adheres to the wet ink — excess falls away cleanly. Cure in a conveyor dryer or heat press at 150–165°C for 12–15 seconds.
Q: Can this powder be used with PET film from any brand?
A: Yes. The Bond Catalyst is compatible with all standard DTF PET transfer films, including cold-peel and hot-peel varieties. Film quality does affect the overall transfer result, but the powder itself bonds reliably across film brands.
Q: How should the powder be stored between uses?
A: The vacuum-sealed packaging protects against moisture absorption during storage. After opening, use the resealable zip closure and store in a cool, dry environment (below 25°C / 77°F). Avoid humidity — moisture causes clumping that degrades application quality.
Q: Does this powder work on dark fabrics?
A: Yes, when used as part of a complete DTF workflow that includes white ink underbase printing. The powder bonds to the white ink layer, which in turn sits on the dark fabric. The transfer's opacity comes from the white underbase, not the powder itself.
Q: What differentiates polyamide powder from TPU powder for DTF?
A: Polyamide (PA) offers superior wash fastness and lower melting points compared to TPU, making it the preferred choice for apparel that undergoes frequent laundering. TPU provides a slightly softer hand feel but sacrifices some durability. Professional print shops overwhelmingly standardize on PA for production work.
