Moisture is UV varnish’s worst enemy

Did you know?

– A tin is never filled up to the top and contains between 10 to 15% of air
– The air around us contains between 0.1 to 5% of water vapor
– A sudden change in temperature causes the water vapor to condense when the dew point is reached

  • This phenomenon can occur in storage containers

– Even at trace levels water can cause wetting problems when applying varnish
– Water is miscible with most varnish solvents

  • Traces of moisture cannot be detected when the tin is opened

What does Altus Coating do to prevent moisture risks?

– All solvents are checked on arrival
– All solvents are dried before being used
– All tins are air-tight
– The finished products are stored under controlled conditions:
Dedicated and closed storage rooms
Pallet storage
Ventilated storage rooms

What are the conditions to be avoided for storage?

– Temperature changes
– Conditions which encourage moisture accumulation
– Never store outside
– Store in a closed, ventilated room
– Do not store on the floor (cold floor phenomenon))
– Wipe tins before use: dust, traces of moisture, etc.
– Once it is open, finish rapidly since it will no longer be air-tight
