SILISIL ·

SILISIL ZA 26 SPRAY B WT 10 THIXO 25 kg is the b-component (platinum catalyst) of the thixotropic 2K spray silicone in a 25 kg industrial container — suitable for ZA 26 Spray A, shear-thinning when sprayed, stable on vertical surfaces.

SILISIL series 2K spray silicones — platinum-curing addition silicones optimized for pneumatic spray application in spray mold making, vertical molding, vacuum forming tools, and multi-layer shell molds. ZA 26 Spray B WT 10 THIXO is tailored to specific industrial and workshop applications — the most important properties and areas of application can be found below.

Pt catalyst component — 25 kg industrial container

SILISIL ZA 26 Spray B WT 10 THIXO is the catalyst component of the platinum-curing thixotropic 2K spray silicone in a 25 kg industrial container — designed for professional continuous use. The curing reaction only starts after mixing with component A (SILISIL ZA 26 Spray A) in the specified ratio. Component B alone will not cure.

What distinguishes ZA 26 Spray B WT 10 THIXO

Precise Pt catalysis
Reproducible networking with batch-to-batch consistency for industrial series production.
Thixotropic setting
Matching the A component — the combined mixture remains thixotropic and suitable for vertical application.
25 kg industrial container
Standard format for spray production plants with high material consumption.
Polyaddition — no loss
No byproducts, no mass loss; the shape matches the original exactly after curing.
Stable storage
Pt catalyst typically has a longer shelf life than component A — see TDS.
Only usable with ZA 26 Spray A
Component B does not harden on its own — see TDS for exact mixing ratio.

What is ZA 26 Spray B WT 10 THIXO used for?

Industrial production
Large-scale molding using spray technology — continuous material supply.
Vertical wall impressions
Architecture and restoration using thixotropic spray material.
Spray multi-layer structures
Layer-by-layer construction of thick mold walls at industrial speed.
Shape preservation of large plants
The 25 kg container supports uninterrupted production.
Film / SFX Industry
Prosthetics studios and special effects workshops with spray equipment.
Architectural restoration
Large-scale restoration projects on facades, ceilings and interiors.

processing

1
Prepare original and spray area
Original clean, dry and dust-free. Spray booth with good ventilation — processing temperature 20–25 °C, relative humidity 40–60%.
2
Homogenize and insert the components
Stir both components (A + B) separately before use and place them into the 2K spray system — for the exact mixing ratio, see TDS.
3
Testing a spray gun
Test the spray pattern on a sample cardboard — adjust for a uniform, thin layer thickness without drops or splashes.
4
Spray on a first thin layer
Spray evenly from a distance of 25–35 cm — first layer as a detail layer, thin and completely opaque.
5
Build up multiple layers
Allow to dry briefly between layers (typically 3–5 layers for complete mold construction). With the thixotropic variant, vertical application is also possible.
6
Vulcanizing and demolding
Pot life and demolding time according to TDS — typical pot life 6–15 min, demolding after 30–60 min, maturation phase 24 h for maximum strength.

Frequently asked questions about ZA 26 Spray B WT 10 THIXO

Practical questions regarding application and compatibility — answered by SILITECH.

SILISIL ZA 26 SPRAY B WT 10 THIXO 25 kg: B-component (platinum catalyst) of the thixotropic 2K spray silicone in a 25 kg industrial container — compatible with ZA 26 Spray A, shear-thinning during spraying, stable on vertical surfaces. Main applications: industrial production, vertical wall molding, multi-layer spray build-ups.

Platinum-curing spray silicones are sensitive to crosslinking inhibitors—sulfur, amine, tin, and phosphorus compounds can locally halt vulcanization. Avoid latex gloves, sulfur-containing modeling clays, some adhesive tapes, and PVC plasticizers near the mold. Ideally, process at 23°C, 40–60% RH. Stir both components separately before placing them in the 2K spray system. Several thin spray coats are better than one thick coat.

No. Silicone sprays leave a water-repellent silicone film that prevents paints, adhesives, and coatings from adhering. Do not use on surfaces that will later be painted or covered with adhesive film—or clean thoroughly beforehand with SILISIL Silicone Remover.

Store the aerosol can below +50 °C, protect from direct sunlight, and keep away from ignition sources. Do not forcibly open or incinerate pressurized containers, even after use. Shelf life in the unopened original container is according to SDS; please note the printed expiration date.

Standard 1:1 mixture with a 6-minute pot life: SILISIL RTV MF-Spray 25-6 (3582). Longer pot life for multi-layer applications: MF-Spray 25-6 Delayed (4128). Thixotropic for vertical surfaces: MF-SprayThixo 25-10 (3583). Pneumatic spray application Shore A 22: VI 22 Spray WT 2 (622). Industrial 2K thixotropic spray system: ZA 26 Spray A + B (1708/1709). Zhermack original brand available as a variant of VI 22 (3910) and ZA 26 (3897).
