Silicone Thixotropic Additive — Brush-On Conversion Agent
Allzone Trading supplies thixotropic additives used to convert pourable silicone mould rubber into a non-sagging, brushable consistency. Studios and precast shops use them to run one silicone stock for both poured and brushed moulds instead of holding two inventories. Compatible silicone families and dosage range are confirmed against supplier technical data at quotation.

Technical & procurement detail
What the additive does+
A thixotropic additive raises low-shear viscosity while leaving the material workable under brushing. In practice the silicone stops flowing off a vertical surface but still spreads and wets detail when worked with a brush. It changes rheology, not chemistry, so the underlying cure system continues to behave as its data sheet describes.
Compatibility and dosage+
Additives are matched to a silicone family — a thixotrope intended for a condensation-cure base is not automatically suitable for an addition-cure base, and vice versa. Dosage is small and its effect is non-linear: too little sags, too much traps air and makes detail coats difficult to work. Always confirm the compatible systems and the dosage window from the supplier's data for the grade supplied, and run a trial batch.
Working practice+
Add and disperse the thixotrope fully into the base before adding catalyst, mix only what can be applied within the working window, and expect a thickened mix to hold more entrained air. The first detail coat is normally brushed thin and worked hard into the surface, with thickened build coats following once air-free contact is guaranteed.
Additive or dedicated brushable grade?+
For occasional vertical work, converting a pourable stock is efficient and reduces inventory. For continuous production of glove moulds, a purpose-formulated brushable grade is usually more consistent because its rheology is engineered rather than adjusted on the bench. Many shops use both approaches deliberately.
Specification options+
Working properties are configurable options within this canonical product, not separate products. Depending on the family, that can include grade, viscosity, mix ratio, pot life and demould time, hardness, colour, particle size or fibre length, and pack format. No configuration is presented as stocked or approved until it is confirmed against the supplier's technical data for the exact material offered. Supplier grade names, factory codes and manufacturer brands are not published here.
What to include in your enquiry+
Send the silicone system you use (condensation or addition cure), the surfaces you need to coat, your typical batch size and how often you build vertical moulds.
Frequently asked questions
Can any silicone be thickened with this?+
No. Additives are matched to specific silicone families and cure systems. The compatible systems are confirmed against the supplier's data for the grade supplied before use.
How much is added?+
Dosage is small and system specific, with a working window rather than a single figure. Follow the supplier data and prove it on a trial batch before applying to a real mould.
Does it affect cure or final hardness?+
It is intended to modify rheology, but any additive can shift working properties at higher loadings. Trial the exact dosage you plan to use and check cure and surface quality on a sample.
Will it make air removal harder?+
A thickened mix holds air more readily, which is why the first detail coat is brushed thin and worked into the surface before thickened build coats are applied.
Is a dedicated brushable grade better?+
For continuous glove-mould production, usually yes, because its rheology is formulated rather than adjusted. For occasional vertical work, converting a pourable stock keeps inventory simpler.
Are technical documents provided before ordering?+
Yes. The supplier technical data sheet and safety data sheet for the exact grade offered are provided with the quotation, and the working properties in those documents govern — not any general description on this page.
What quantities are quoted?+
Quantities are reviewed per enquiry, from trial quantities through to pallet and full container programmes for production users and distributors.
