Question 1

What EN204 durability class does PVAc-50 meet, and what does this mean for substrate selection?

Accepted Answer

PVAc-50 meets EN204 Class D3, qualifying it for interior applications subject to short-term high humidity or brief water exposure — suitable for furniture, kitchen cabinets, and joinery. It does not meet D4, so continuous immersion or unprotected exterior exposure is not recommended without additional surface treatment.

Question 2

What pressing parameters are recommended for PVAc-50?

Accepted Answer

Apply to one or both substrates at 150–250 g/m². Press at 0.3–0.8 N/mm² for 20–40 minutes at 15–25°C. Cold press at room temperature is sufficient; heat pressing accelerates set time but is not required. Full mechanical strength is achieved after 24 hours.

Question 3

Is PVAc-50 compatible with waterborne and solvent-borne finishing topcoats?

Accepted Answer

Dried PVAc-50 film is compatible with most waterborne lacquers and stains after full 24-hour cure. Remove squeeze-out before the adhesive dries to prevent sanding difficulties. For solvent-borne topcoats, ensure complete cure first, as residual solvents can re-emulsify partially dried PVAc film and cause adhesion failure.
