Question 1

How does EAC-50 achieve VOC compliance in zero-VOC architectural paint formulations?

Accepted Answer

EAC-50 has a boiling point above 250°C, placing it outside the VOC definition under EU Directive 2004/42/EC and the US EPA Method 24 regulatory threshold. This means EAC-50 functions as an effective coalescent without contributing to VOC limits, enabling zero-VOC labelling at standard use levels of 1–3%.

Question 2

What film properties can formulators expect compared to conventional Texanol coalescent?

Accepted Answer

At equivalent MFT-reduction dose, EAC-50 typically delivers equal or superior König hardness (≥100 s at 7 days, 23°C/50% RH) and 60° gloss values comparable to Texanol in acrylic latex systems. Its ester-alcohol structure provides good compatibility with pure acrylic and styrene-acrylic binders without adverse effects on viscosity or heat-age stability.

Question 3

Is EAC-50 suitable for low-temperature application conditions?

Accepted Answer

Yes. EAC-50 at 2–3% on emulsion weight provides reliable film formation down to 5°C in standard acrylic latex paints, meeting requirements for all-season exterior application. For temperatures below 5°C, a secondary fast-evaporating co-solvent such as PnB at 1–2% may be added without losing zero-VOC status provided total formulation VOC remains below the regulatory threshold.
