TIBP is a highly soluble defoamer and anti-foaming agent. Excellent ability to both destroy foam and act as a foam inhibitor.

TIBP / TBP TDS TIBP / TBP SDS

The perfect choice when flow and pumpability are of high importance. Melamine Sulfonate works extremely well with gypsum systems, offering faster set times. Bisley distributes the Plastyn SP range in both liquid and powder form.

With excellent dispersing and wetting properties, naphthalene sulfonates have been a workhorse of the building chemistry industry. Bisley exclusively market the BISPLAS range of naphthalene sulfonates, available as both a calcium and sodium salt, with a variety of sulfate grades available. Formaldehyde free grades are also available.

BISPLAS TDS BISPLAS SDS

Bisley exclusively markets and distributes the Bisflow™ Ultra range of PCE for the gypsum industry. Bisflow™ Ultra is a high range superplasticizer with low dose efficiency, optionally available with an added defoamer for easy formulation.

Bisley carries a range of powder additives for air-entrainment and foam generation. Foaming agents can play a major role in reducing the density of the drywall (gypsum board), which allows for ease of handling, thermal insulation, sound proofing, shorter drying times and savings in raw material costs.

E-Glass chopped strand fiber is composed of a calcium aluminoborosilicate glass and is widely used as an additive to reinforce composite materials such as gypsum and fiber glass composites. Its high temperature stability makes it useful in fire resistance materials. Bisley supplies 6mm and 12 mm fine chopped E-glass fiber, other fiber sizes may be available upon request.

E-Glass TDS

Extremaspheres™ are expanded foam glass spheres ideally suited for light color and light weight renders, mortars and concrete. Extremaspheres™ are a lightweight aggregate made from recycled glass, chemically resistant, low in density, resistant to pressure and act as a thermal insulation, acoustic absorption. Highly suited for use in insulation, fireproof renders and cement board.

Extremaspheres™ TDS Extremaspheres™ SDS

Microspheres, also known as cenospheres, are thin-walled hollow ceramic spheres that can be used to modify rheology, reduce weight and shrinkage and improve thermal insulation. With high crush strength, suitable for all lightweight mortar and render applications. Bisley supplies a range of microspheres known as Biscil.

Synthetic L+ and DL tartaric acid are available as a free-flowing powder (with anti-cake) and in granular form. Tartaric acid is an extremely effective retarder (especially for alumina cement systems) at very low dosages.

Tartaric Acid TDS Tartaric Acid SDS

Sodium Trimetaphosphate (STMP) is used as a gypsum additive that optimizes setting time and enhances structural integrity. Bisley supplies a variety of grades and customizable specifications.

STMP TDS STMP SDS

Cellulose ethers extend the open time / workability of mortars and glues. With extremely low addition rates, cellulose ethers can modify the flow properties of the cement mortar water retention, making water available to the slurry over time. Bisley supplies a full range of MCs, HECs and HPMCs.

Combizell B6000 HEC TDS

Dispersible polymer powders are easily dispersed in water and form stable emulsions. RDPs can improve adhesion, flexural strength and workability of modified compounds. Bisley supplies the Neolith range of RDPs.

Plaster mixtures containing STMP can improve compressive strengths of the boards as well as mechanical stability. STMP has been shown to have an excellent effect on reducing sag deflection. STMP does not have the effect of retarding the setting, meaning it does not increase the re-conversion rate of calcined plaster into calcium sulfate dihydrate.
