Lead-free Enamel Painting?
+++++++
We have problem in painting of springs. Due to EC regulation
enamel paints are to be lead free
is there a paint which is lead free as such
if so who is manufacturing and details of it?

In Europe it is almost impossible to buy paint that does contain
lead. All paint is lead free.
I do not know the situation in India but speak to your paint
supplier. You may not have a problem.

Mr. Geoff Smith,
Thanks a lot for the response.
May I know what is the limit of lead that is acceptable in Europe as
it is difficult to make a paint as Lead free?

My earlier reply was a little simplistic. You are quite right; zero
lead content is difficult.
There is no single piece of legislation covering lead in paint but
the best summary I can manage is ...
Lead is still used in some industrial paints for special purposes
such as red oxide primers for marine and structural steel but is
being phased out.
Some pigments may contain lead (as chromate or molybdate etc) but
above 0.5% cannot be sold to the public. There are exemptions for
artists paint and for use on historic buildings.
Lead is occasionally used as a catalyst for some resin systems but
the concentration would be around 0.0005%
Lead driers may be present in some alkyd paints at 0.05-0.1%
Paint containing greater than 0.15% must be labelled "Contains
Lead"
Paint containing more than 0.5% must also be labelled with a skull
and crossbones.
It would appear that less than 0.15% is considered zero.
When I have had need for very low lead, I have had to test each batch

Hi,
I bought a bed for my baby four months ago. The salesperson said they
used lead-free paintings on their products and I bought the
furniture. But, the paintings is still smelling and I am worrying
about my baby's health. Is it normal or should I change the
bed?
Thanks for your time.

It is unlikely that there is lead in the paint, but if a strong
solvent smell persists for months, the paint is apparently not
properly cured. While it is very difficult to say for sure whether
these solvent smells pose any hazard, neither a baby bed nor and
other furniture should have a persistent smell. I think you should be
entitled to return it as defective whether it poses a hazard or not.
