Pigments and additives
Jesmonite pigments
Jesmonite pigments are aqueous dispersions
compatible with Jesmonite composites. When dispersed in Jesmonite-based materials, they offer excellent chemical and thermal stability. Call us for more details. The pigments are available in 50g, 200g, and 1000g bottles.
The shelf life of Jesmonite Pigments is 24 months from the date indicated on the packaging.
Jesmonite retarder
The setting times of all Jesmonite composite materials can be extended by adding a retarder to increase working time. There
is a retarder for AC100, AC200, and AC300 materials, and a separate retarder for AC730, AC830, and AC930 cement-based materials.
Please note that the end-user must perform tests in the workshop environment, as extreme temperatures and humidity can affect setting times. Addition rates can be found in the user guides for the various composites.
Quadriaxial fiberglass
This type of reinforcement is tailor-made for use with Jesmonite. It is based on the latest multi-axial glass reinforcement technology, which makes Jesmonite fiberglass laminates light, strong and fire-resistant. It is constructed like a lace, with continuous glass strands in four axes (multiaxial) sewn together using Nomex® fireproof material.
There are very few loose filaments, making the glass safe and comfortable to use. It
can be precisely cut with scissors or roller cutters, and
adapts to the most complex shapes.
This makes it particularly suitable for mold making and panel construction. Please note that fiberglass mats (CSM) intended for use with solvent-based resins such as polyester are not suitable for Jesmonite materials.
Chopped fiberglass
Jesmonite Chopped Glass Strands can be added to all Jesmonite composites to
provide increased strength to thin-section castings, and also to act as a filler
to aid in lamination. Jesmonite Chopped Glass Strands are available
in three types: 6mm and 12mm in standard glass, and 13mm in alkali-resistant glass which are
specifically designed for use with Jesmonite AC630 to create a premix. Chopped
strands can also be used to add impact resistance when
applying thin sections of Jesmonite to sculpted polystyrene objects.
Fiberglass PVA
PVA fibers are the new alternative to glass reinforcements for
cement systems. They are a synthetic polyvinyl alcohol fiber
whose chemical and physical characteristics make them
particularly suitable for the Jesmonite family, which uses
polymer-modified cementitious materials. They have high
strength combined with low elongation and high modulus. They
offer advanced adhesion to the polymer cement matrix as
well as inherent resistance to the degrading effects of the alkalinity of such
a matrix. We strongly recommend their addition to Jesmonite systems
to resist frost damage in the harshest outdoor environments.
