Question 1

How do phase change material microcapsules regulate indoor temperature in building coatings?

Accepted Answer

The PCM core (typically a paraffin or fatty acid with melting point 23–26°C) absorbs heat when the room temperature rises above the phase change point, storing thermal energy as latent heat during melting. When the temperature falls, the PCM solidifies and releases the stored heat back into the room. This thermal buffering effect dampens indoor temperature swings by 3–5°C, reducing peak cooling load and HVAC energy consumption by 10–20% in well-insulated buildings.

Question 2

Can PCM microcapsules be incorporated into standard interior wall paint or render?

Accepted Answer

Yes, the 30% slurry can be blended into interior emulsion paint at 15–30% addition by weight (final PCM loading ~5–10% in dry film), or into mineral render, gypsum plaster or drywall compound at 20–40% addition. The melamine-formaldehyde shell is chemically stable and compatible with both water-based and solvent-based binders. Avoid high-shear mixing that can rupture capsules — use gentle stirring at <500 rpm. Minimum recommended application thickness is 3 mm for meaningful thermal performance.
