What that means in practice

The LM variant of A 74 L at the same K74 with an identical published application list. VESTOLIT do not say on this page what LM changes, so treat the two as distinct products and ask — matching numbers are not evidence of interchangeability.

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 A 74 LM

• Paste resin is dispersed into plasticiser and fused, not extruded — so plastisol viscosity and how it behaves over time matter far more than the K-value alone. Ask for viscosity data, not just the grade name.
• Gelation and fusion behaviour decide whether it works on your line. Two grades at the same K-value can gel quite differently.
• For automotive, apparel or anything enclosed, ask about fogging and emissions — paste grades are specified against those and ordinary coating grades may not be.
• Check storage and age. Paste resin absorbs moisture and plastisol behaviour drifts, so a lot that has sat a long time is a different proposition from a fresh one.
