Jesmonite AC100 is an Acrylic Composite material supplied in two parts, a powder and a liquid. It is suitable for both decorative castings and glass reinforced laminates, and can be pigmented using the Jesmonite range of water-based pigments. It is also possible to add a range of decorative and functional fillers in order to achieve a wider range of effects and to meet a broader spectrum of specifications. jesmonite AC100 can be used both internally and externally, although external use requires the application of a suitable sealer or external paint system for long-term exposure.
Jesmonite AC300 is a low cost alternative to AC100. It is designed for applications where ultimate performance of AC100 is not required. It is supplied as two components; a water-based acrylic liquid, and a mineral powder. AC300 contains less Acrylic resin than AC100 and as such is an economic alternative where external durability is not required. Jesmonite AC300 is designed for internal use only, however it is suitable for short-term external projects such as exhibitions and props. If used externally a sealer or suitable paint system is recommended to protect surface appearance.
Jesmonite® AC730 Flex Liquids are supplied as an alternative to standard AC730 Liquids to create laminates with increased flexibility. The Flex liquids are also ideal when Jesmonite AC730 is used as a coating for Polystyrene for external sculpture - the increased flexibility reduces the likelihood of cracks forming in the coating due to moisture build up and thermal movement. The use of Flex liquids also means that Jesmonite paste pigments can be used to create colourful casts for external use
This type of glass reinforcement is tailor made for use with Jesmonite. It is based on the latest multiaxial glass reinforcement technology, which makes Jesmonite fibre-glass laminates light and strong. It is constructed like a lace, with continuous glass strands in four axis (multiaxial) stitched together using the fireproof material Nomex®. There are very few free filaments, making the glass safe and comfortable to use. It can be accurately cut using scissors or roller cutters, and will conform to even the most complex shapes. This makes it especially suitable to mould making and Jesmonite panel construction.
Jesmonite Pigments are aqueous dispersions compatible with Jesmonite Composites. When dispersed in Jesmonite materials they offer excellent chemical stability, heat stability, and UV resistance 2% will produce a strong, saturated colour. For lighter colours simply reduce the addition rate until the desired colour is achieved. Pigments can also be intermixed to produce any colour.
Jesmonite sealer can be used for :A coating for internal products, apply one coat of sealer by brush or spray to the product to give a clear satin finish. Also used to prevent finger marking and provide a near matt finish.
Thixotrope is added to the mix to thicken the material to a ‘Gel-Coat’ consistency and so that the viscosity of Jesmonite can be adjusted to the users preference. This is useful when brushing or spraying materials onto moulds with vertical faces as it prevents the material from slumping.
This is a universal release wax that will offer excellent release from a wide range of rigid mould compounds including plaster, Jesmonite, GRP, metal, wood, and glass. It can also be used on production equipment such as scales and casting tables to assist in cleaning. Please note that some porous surfaces such as plaster and timber may need to be sealed before release wax is applied, and trials should be carried out to ensure that the product is suitable.
