What that means in practice

The one copolymer in the B paste series, at K67, and the only grade here listing automotive underbody coatings. UBC is a demanding, adhesion-critical application — which is exactly why a copolymer rather than a homopolymer is specified for it.

If K-values are not something you work with daily, our PVC grades and pricing guide explains what they measure and how prime, off-spec, regrind and regranulate differ.

What to check before buying VESTOLIT B 7090 Ultra

• Copolymer is bought for solubility and adhesion rather than mechanical strength — confirm the comonomer and content, because that is what determines whether it dissolves in your system.
• The K-value is low by design here, not by compromise. Do not read K48 to K50 as a lesser resin; it is what makes solvent-based ink and coating work possible.
• For coating and ink work, ask about colour and clarity on the actual batch. These end up in visible surfaces.
• Confirm it is genuinely a copolymer and not a homopolymer being offered loosely as one — they are not interchangeable and the price should not be either.
