Applications:
Applications:
• AC200 Liquids 1 part by weight AC200 Powders 2 parts by weight. It is also possible to mix the material into a thick paste to produce a fast set which will help to fill joints, air bubbles, or to join castings.
Thixotrope Thixotrope is added to the mix to thicken the material to a ‘Gel-Coat’ consistency. This is useful when brushing or spraying materials onto moulds with vertical faces as it prevents the material from slumping. Thixotrope is added to the mix after the powders, and is mixed in using the High Shear Mixing Blade. Add drop by drop until the desired consistency is achieved. Typical inclusion rates by weight are 2g – 6g per kilo of mix.
• Adding Pigments If a colour is required, Jesmonite paste pigments can also be added to a maximum of 2% by weight,.
• Casting For simple casts pour a small amount of the mix into the mould. With a brush, coat all accessible surfaces with material to help reduce air bubbles. If access is difficult then rotate the mould so that the mix flows over the surface. Gentle tapping will also help ensure that air rises to the back of the cast.
• Jesmonite AC200 contains a high quality pure acrylic resin that can be polished with a clean cotton cloth. Excellent results can be achieved with a wide range of waxes and polishing machinery, and Jesmonite AC200 is also compatible with a wide range of water-based sealers and varnishes.
Properties
Properties
Jesmonite AC200 is supplied as two components, a water-based acrylic liquid, and a mineral powder. The material is formulated for making masters and prototypes for moulding and sets to a hard but easily carved surface finish.
Hardened Jesmonite can be machined or shaped using a variety of machine tools including CNC machines, routers. As well as hand tools such as rasps, chisels.
Jesmonite can be finished with sandpaper.
Jesmonite can be moulded using a rubber moulding compounds.
Jesmonite can also be used in to mould with.
AC200 works as an adhesive for polystyrene, PU tooling board, and Styrofoam boar.
Durable
Flame resistant
Resistant to impact.
When mixed, it accepts coloured pigments and metal powders. Its surface can be finished to resemble plaster, stone, metal, and wood.
Sustainability:
Sustainability:
Jesmonite contains acrylic polymers, no Volatile organic compounds (VOCs), Water-based not solvent-based, making it currently kinder to the environment. Jesmonite is not biodegradable.
Material Handling:
Material Handling:
Jesmonite is considered a low hazard material.
The finished composite emits no toxic fumes. The mixing process requires no harmful solvents. However, the mixing should be performed with rubber gloves, eye protection, and dust mask, and should take place in a well-ventilated area. Cleanup is performed with water.
