How to Choose the Right Primer for Your Printing Project

When it comes to printing on challenging materials like glass, metals, or plastics, the right primer or adhesion promoter can make all the difference. Choosing the correct product ensures strong ink adhesion, vibrant print quality, and long-lasting performance. At Boston Industrial Solutions, Inc., we know there’s no one-size-fits-all solution for adhesion, which is why we offer a wide range of specialized UV primers and adhesion promoters tailored to specific substrates and applications. Our primers are formulated with low VOCs and are non-toxic making them safer for operators and facilities.

Why Adhesion Promoters Matter

Primers and adhesion promoters aren’t just add-ons: they’re essential pre-treatment chemicals that modify a substrate’s surface so that ink will bond permanently. In digital and industrial printing, this means improving mechanical and chemical adhesion so that the prints resist scratching, peeling, and wear.

Without the right adhesion promoter, even the most advanced UV LED inks may fail to stick to low-energy surfaces like polypropylene or metals like stainless steel.

Choosing a Primer

Different materials require different chemistries. The primer needs to be formulated specifically for your substrate whether that’s a low-surface-energy plastic like polypropylene, a smooth surface like glass, or a metal one like aluminum and stainless steel.

Here’s how some of our primers line up with common substrates:

Conclusion

Choosing the right primer or adhesion promoter is a combination of understanding your substrate and the performance you need. By matching these factors with the correct products, whether it’s a plastic-specific primer, a heavy-duty metal adhesion promoter, or a high-tech jettable solution, you set your project up for long-lasting, high-quality results by choosing our specially designed primers.
