Butanone - C1501 (also known as Methyl Ethyl Ketone (MEK)
MEK is highly inflammable and can be irritating to the eyes and respiratory system. Repeated exposure may cause skin dryness or cracking and the vapours can cause drowsiness and dizziness. MEK is effective in 'welding' ABS to itself, plywood and polystyrene. Normal application is by brush, but if you want to deposit a measured quantity, with minimum 'creep' to adjacent work, try using a lining pen. With some practise you will soon be able to, for example, glue windows, without getting solvent on the face of the material.
Plastic Weld - C1502
This covers a much wider range of plastics than Butanone. However, we still recommend that you regard Butanone as your first solvent and it should always be used on our chairs and sleepers.
As with the use of all solvents, care should be taken with Plastic Weld. It is Methylene Chloride - widely used in the plastics and Perspex industries. However the vapour is harmful and it is a Category 3 carcinogen. Treat it with respect.
It is important to understand there is no such thing as a safe solvent. All have drawbacks. Some are irritants, others are classed as carcinogens. Many are highly inflammable. All should be handled with care. In particular, always provide adequate ventilation and never smoke whilst using them.
We will happily supply a copy of the relevant Safety Data Sheet for our solvents as this will give you an understanding what to do in case of an emergency.
Please, take care when using solvents. Keep the area well ventilated, keep it away from sources of ignition, do not smoke, and do not breathe the vapour.
