in the world of moulding. A range of ancillary products is also supplied further extending the materials versatility.

It is essential to use both accurate scales and a Jesmonite High-shear Mixing Blade to ensure that the
compound performs within its specification. Failure to follow these instructions can lead to strength loss, slow
cure, and reduced durability. Workshop conditions should be warm, dry, and out of direct sunlight. Environments
where solvent-based compounds are in regular use should be avoided. Mixing containers should be clean and
dry, and of a suitable size.


The standard mix ratio for AC300 is as follows:
AC300 Liquids 1 part by weight
Jesmonite Base 2.5 parts by weight
