Technovit Provil (Impression Putty) – Silicones
• Highest reproduction accuracy (< 0.1 µm)
Thanks to the special material properties of Technovit Provil, it is possible to reproduce surfaces with an accuracy of deviations of less than 0.1 µm. As a result, the most precise structures of etched structural surfaces can be displayed, for example in metallography. Technovit Provil creates exact 3D replicas of the molded surfaces. The impression can be cast with suitable plastics (Technovit 3040) without loss of quality in order to obtain a second positive.

• Optimum resilience with complicated geometric objects with undercuts
Thanks to its optimum resilience, Technovit Provil makes it possible to mold difficult areas and to measure them after the impression has been taken. The advantages are z. B. used to measure the degree of wear of cavities in tools and machine parts without having to use cost-intensive methods.

• Error-free work thanks to the simplest application
Incorrect dosing is ruled out by self-mixing cartridge systems. For the kneadable products, the associated spoons and products are color-coded so that there is no confusion.

• Can be used in just a few seconds thanks to the simplest of mixing
. No prior knowledge of the application is required. Technovit Provil is often an advantage over other methods in hard-to-reach places or when working overhead. Technovit Provil can be easily detached from the specimen without leaving any residue.

• Inexpensive process
Technovit Provil requires no investment in equipment or special application training. The favorable price of the consumables and the low time required for the application makes the decision for Technovit Provil easy!

• No hazardous goods
Technovit Provil guarantees risk-free use in all areas that already harbor a high risk potential (e.g. corrosion assessment in tank systems, gas lines, etc.). The transport of Technovit Provil silicones also does not pose any risk, since the products are approved for all types of transport.

• No temperature development during hardening
Technovit Provil hardens without increasing the temperature, which means that the surface quality of the objects is not negatively affected – important for a wide variety of scientific applications and impressions, especially in the restorative area.

• Diverse evaluation and application
options Technovit Provil silicones do not show any reactions with other agents. Impressions of almost any type of surface, regardless of the material of the object possible. The evaluations can be carried out using a light microscope or using the SEM (with a low acceleration voltage of max. 5 KV). Roughness measurements can also be taken on Technovit Provil impressions.

Technovit Provil Putty and Technovit Provil Putty soft (Impression Putty)
The silicones Technovit Provil putty and Technovit Provil putty soft consist of a base and a catalyst component and can be kneaded by hand.
Application
The components are presented with the respective dosing spoons 1:1. Mixing is done by hand until a homogeneous mass is obtained. For molding, the mass is modeled or pressed onto the desired surface. The silicone is completely hardened after 4.5 – 5 minutes at room temperature and can be removed or the object can be demoulded.

Areas of application
The two products essentially differ in their final hardness (see technical data). Technovit Provil Putty and Technovit Provil Putty soft are used for taking impressions where:
• there is a simple surface
• the object has a correspondingly high surface hardness (metallic or mineral surfaces)
• a high final hardness of the impression is required.
• the object has a correspondingly high surface hardness (metallic or mineral surfaces)
• a high final hardness of the impression is required.
A typical application is molding for measurement in mold and tool construction. A combination with the flowable Technovit Provil light is also possible, in that Technovit Provil Putty is used as a “stamp” or for rough impressions and Technovit Provil light CD2 is applied for fine flow and reproduction of the existing microstructures.
Technovit Provil Light
Technovit Provil Light is a low viscosity, self-mixing silicone. The material is supplied in double cartridges.
Application:
The application system guarantees safe and error-free use. The cartridges are inserted into the dispensing gun. A mixing cannula is then placed on the outlet opening of the cartridge with a half turn. By pressing the lever of the dispensing gun, the silicone is pressed evenly out of both chambers of the double cartridge through the mixing cannula. This automatically mixes the silicone homogeneously and applies it directly to the object. The mixing cannulas also serve as a closure until the next application. Mixing cannula attachments can also be used to fill the smallest pores or cracks.
Application areas
Technovit Provil light is a very free-flowing silicone and is therefore ideally suited for molding difficult geometric shapes . After about 4.5 minutes, Technovit Provil light has hardened and can be removed from the object.
Technovit Provil BLACK
The uniquely high tensile strength and elasticity make it possible to precisely mold geometric shapes with Technovit Provil BLACK and demould them without defects.
Technovit Provil BLACK does not show any reactions with other agents and can be used for almost any type of surface impression, regardless of the material of the object. The impressions made can be evaluated microscopically or using laser and roughness measuring devices.
