Abstract
Rubber articles e.g. rubber latex gloves have an adherent anti-tack coating comprising a mixture of a) a carboxylated synthetic rubber latex having a minimum film forming temperature (MFFT) of 10.degree. C. or above, with b) a latex polymer having an MFFT below 10.degree. C. and/or c) a water-soluble organic polymeric hydroxy material. Component b) tends to confer non-slip properties while component c) tends to confer lubricating properties.
Claims7
An article of rubber having a surface provided with an adherent anti-tack coating which coating comprises a mixture of:
- a carboxylated synthetic rubber latex polymer having a film forming temperature (MFFT) of 10.degree. C. or above;
- with a partly or wholly water-soluble organic polymeric hydroxy material;
- the weight ratio of the said carboxylated synthetic rubber latex polymer to the said partly or wholly water-soluble organic polymeric hydroxy material in the anti-tack coating being from 0.25:1 to 20:1.
