Prevulcanised Liquid Latex PVML Dipping Rubber 250ml -10 litre

Professional grade pre-vulcanised compounded casting and moulding latex for use in the creation of high quality, high performance, moulds, masks, and models as well as for use in theatrics, SFX and various Arts and Crafts applications.  The high solids content of over 60% permits the reproduction of the finest detail.  Low ammonia, skin-safe* (*Read label), with a long storage life the latex can be poured brushed or dipped. High stability, easy to use, and can be coloured using normal acrylic paints.

Vulcanisation is a chemical process in which the latex is heated with sulphur, accelerator and activator at 140160°C. The process involves the formation of cross-links between long rubber molecules so as to achieve improved elasticity, resilience, tensile strength, viscosity, hardness and weather resistance. Although (dried) latex will naturally vulcanize if left at room temperature over time the pre-vulcanisation removes any delay in the mould making process and makes the latex easier to use. . 

Thickening. Some applications can benefit from the application of the latex in slightly thicker layers and this can be achieved by using a thixotropic (thickening) agent to the latex prior to use.  Thickeners are available via the drop down menu on this listing.

Simply add the thickener to your latex at a rate of between 1% and 5%, stir it and brush on to the mould. We recommend introducing the thickener after doing one or two layers using un-thickened latex.

The thickening liquid thickens latex approximately 3 times. An alternative thickener is latex thickening powder, 50g is equivalent to approximately 0.5 to 1 litres of liquid thickener, but much thicker latex can be achieved. 

Storage. The product should always be stored away from UV light at a temperature between 10 and 38

Safety. Always use in a well ventilated area. *Skin Safe, read label carefully. Do not use this product if you have known allergies to rubber latex. If you're unsure, ask your doctor for advice. If an allergic reaction occurs, stop use and seek medical help.
