Liquid additive for latex that increases durability, protects against UV and extends the service life of masks and moulds. Dosage 100:2 to 100:3.
Permatex is a liquid additive formulated to be incorporated directly into latex to improve its long-term properties. It increases wear resistance, protects against UV light degradation and extends the service life of masks, prosthetic effects and any latex moulded piece that must withstand continuous use or environmental exposure.

What it is used for
Permatex is designed for any professional or semi-professional working with latex who needs their pieces to last longer without degrading, without losing flexibility and without the colour deteriorating from light exposure. It is especially useful when pieces will be displayed in shop windows, collections, or are used repeatedly on film sets or events.
- Latex masks for professional use or as props
- Castings and moulds in prosthetic latex for special effects
- Latex pieces exposed to artificial or solar light on a continuous basis
- Collectible or display items made from latex
- Productions where masks are reused across multiple sessions
- Any latex piece requiring greater service life and wear resistance
How to use it
- Shake the base latex well before preparing the mixture.
- Weigh or measure the latex you are going to use.
- Add Permatex at a ratio of 2 parts per 100 of latex (100:2). Do not exceed 3 parts per 100 (100:3).
- Mix with slow, continuous movements to avoid incorporating air bubbles.
- Apply the latex with Permatex as you normally would: in layers, with a brush or by dipping, depending on your technique.
- Allow each layer to cure completely before applying the next.
- Once the piece is finished, you can paint it with paint specifically formulated for latex for a professional finish.
Usage tips
Respect the maximum dosage
Exceeding the 100:3 ratio does not improve results and can alter the mechanical properties of the latex, reducing its strength or affecting the cure. The 100:2 dosage is the most common and sufficient for most applications. Reserve the 100:3 ratio for pieces that will be exposed to more aggressive light or wear conditions.
Correct storage
Latex and its additives are sensitive to cold. Never store Permatex or mixed latex below 0 °C: freezing irreversibly destroys the emulsion. Store the product in a cool, dry place away from direct heat sources or sunlight. If the container has been exposed to low temperatures, check the texture before use.
Integration into your latex workflow
If you use anatomical armatures such as the ED HEAD H2.0 or ALANNA HEAD H2.0 models to build masks layer by layer, incorporating Permatex from the first layer ensures that the entire internal structure already carries the UV reinforcement built in. This way you are not relying solely on the exterior finish to protect the piece.
Frequently asked questions
Can this type of additive be added to any latex?
Permatex is formulated for latex used in moulding and special effects. It is compatible with mask latex such as RD-407 Masking Latex and with prosthetic latex. Before using with an unknown latex, carry out a small test to verify compatibility and that it does not affect the cure.
What happens if I add more than the recommended amount?
Exceeding the maximum ratio of 100:3 can compromise the physical properties of the latex: lower tensile strength, variations in cure time or uneven finishes. Always respect the indicated range to obtain the best results.
Does this additive change the colour or transparency of the latex?
At the recommended dosages (100:2 to 100:3), Permatex does not appreciably modify the colour or appearance of the latex. If you subsequently want to paint the piece, you can use Mask Paint, which adheres perfectly to latex and maintains flexibility.
Is UV protection superficial or does it affect the entire piece?
By being mixed directly into the latex before application, the UV protection is integrated throughout the entire mass of the piece, not just on the surface. This makes it far more effective than surface treatments applied after curing.
Can it be used on pieces that have already been made?
No. Permatex is an additive that is incorporated into liquid latex before application. It cannot be applied to already cured pieces to improve them retroactively. Its function is preventive: it protects the piece from the moment of manufacture.
How much longer does latex treated with this additive last compared to untreated latex?
The improvement in durability depends on conditions of use and storage, but for pieces exposed to continuous light the difference is significant: latex without UV protection tends to yellow, crack and lose elasticity more rapidly. With Permatex, this process is slowed down considerably.
Is there any risk when handling this product?
As with any chemical additive, it is recommended to work in a well-ventilated space and avoid prolonged contact with skin and eyes. Consult the product's SAFETY DATA SHEET for detailed information. Always store above 0 °C to prevent emulsion degradation.
Is it necessary to use this additive if the piece is only going to be used indoors?
Even indoors, artificial lighting (especially studio spotlights, high-intensity LED lighting or indirect sunlight through windows) can degrade latex over time. If the piece is for permanent display or repeated use on film sets, incorporating Permatex is good practice that will extend its service life.
