ZA FAST-SIL Zhermack - Silicone RTV2 type of putty addition for quick moulds

Modelled Silicone for rapid realization of flexible moulds

ZA FAST-SIL Zhermack RTV2 two-component silicone with addition vulcanization, having a type consistency putty / moltable paste. Unlike liquid RTV2 silicones, the material can be mixed and manually applied to the model.

The main advantage of ZA FAST-SIL is working speed. At 23 ° C, the product has a working time of approximately 3 minutes And a curing time of approximately 12 minutes, being designed for the rapid realization of molds and reproductions.

After vulcanization, silicone has a hardness of 38 Shore A And keep the precision necessary to reproduce the model details.

Recommended applications

According to the technical documentation Zhermack, ZA FAST-SIL is mainly intended for use rapid realization of molds.

Quick flexible moulds for the reproduction of objects;
rapid reproductions of the surface models and details;
direct application mouldwhen the modelling consistency is more practical than a liquid silicone;
local applications or difficult geometrywhere the material can be positioned and pressed manually;
casting of metals with low melting temperatureUnder the conditions indicated by the manufacturer.

Low melting temperature alloys

Due to the thermal resistance of the vulcanized silicone, Zhermack mentions the possibility of pouring directly into the molds made from ZA FAST- SIL of some Metals with low melting temperaturelike pewter and other low melting-point fusion alloys.

This application should be limited to materials and temperatures compatible with the declared heat field for vulcanised silicone.

Important: Technical values are provided by the manufacturer as indicative values and should not be used for the elaboration of specifications without verification of the applicable technical documentation.

Temperature influence on working time

The values of 3 minutes for working time and 12 minutes for curing time are determined at standard temperature of 23°C.

At temperatures above 23 ° C, working time and curing time shall be reduced. At temperatures below 23 ° C, both times increase considerably.

Best TOOLS Recommendations

FAST- SIL ZA is recommended when speed and manual application controlled are more important than the fluidity of a liquid RTV2 silicone.

Working time of approximately 3 minutes requires the process to be organized before mixing. Prepare the model, weigh the components and set up the application area before you begin the kneading.

For large parts or processes that require a long time of application, short working time must be taken into account before the product is chosen.

Complementary products useful for the use of FAST-SIL ZA:

precision scale - for correct dosing of components in ratio 1: 1;
Proper protective gloves - for handling the material according to information in the safety data sheet;
materials for the construction of the mould - depending on the geometry of the model and the process used;
compatible demoulding agents - only when the application requires a release agent and its compatibility has been verified.

FAST- SIL ZA

Conclusion

ZA FAST-SIL Zhermack is a putty-type RTV2 silicone addition designed for rapid realization of the moulds. Mixing ratio 1: 1, working time of approximately 3 minutes and hardening in about 12 minutes at 23 ° C allows for quick obtaining a flexible mould without the need to pour a liquid silicone. Modelable consistency makes it particularly useful when the material is to be positioned and manually controlled on the model.

Preparation and use

Weigh equal amounts of BASE AND CATALYSTrespecting the ratio 1:1. The correct proportion must be respected for obtaining the declared final characteristics of the product.

The two components mix vigorously by kneading until a complete homogeneous colour. After mixing, the material is ready for application.

Because the working time is only about 3 minutes at 23 ° CThe model and all necessary materials must be prepared before the mixing begins.

Prepare only the amount of material you can mix and apply within the available working range.

Important limitations and recommendations

Respect the exact mixing ratio 1:1.
BASE and CATALYST should be used together only if they have same batch number.
The surfaces that come into contact with the material must be clean, dry and fat-free.
The manufacturer recommends carrying out a small quantity test before extending the use to a larger application.
Vaseline oil can inhibit vulcanisation. Perform a preliminary test if it is present in the trial.
Prepare the model before mixing the components, because the working time is very short.
If necessary, compressed air may be used to facilitate the separation of the mould model.
Do not use tools to force the mould pattern separation.
Read the safety data sheet before handling the product.

Storage and term of validity

ZA FAST-SIL has a stated shelf life of manufacturer 18 monthsif stored correctly at temperatures between 5 ° C and 27 ° C. The date of use of each batch shall be indicated on the product label.

After use, the containers should be properly closed. Do not reverse the caps of BASE and CATALYST containersto avoid contamination of components.

Preparation and application

Weigh equal amounts of the two pastes and use a different spatula for each component.
Knead until the colour and consistency are uniform.
Press onto the clean, dry model, starting in one area and working progressively.
Do not change the 100:100 ratio and avoid contamination with substances containing sulphur. Check the batch working time before preparing a mix.

Consult the safety data sheet and batch label before use.

Frequently asked questions

What is ZA FAST-SIL?

ZA FAST-SIL is a addition, two-component and modelling RTV2 siliconeintended for mould-making applications. The system consists of BASE and CATALYST, which weigh in equal quantities and mix in the ratio 1:1.

CATALYST component is white and BASE component is light purple. After mixing, the material has a homogeneous colour light violet.

The putty-type consistency allows the material to be modelled and pressed directly onto the surface to be reproduced without the flow behavior specific to a liquid RTV silicone.

When is an RTV2 putty silicone useful?

ZA FAST-SIL is a practical alternative when it is not necessary to pour a liquid silicone or when the geometry of the work favors the direct application of a modelling material.

Its consistency can be beneficial for local interventions, small objects and areas where the operator wants to manually control the positioning of Silicone. It can also be used for the construction or completion of volumes in the process of a mould.

For the choice between a liquid silicone and a putty silicone, the geometry of the model, the level of detail required and the method by which the mould will be built must be considered.

What is the difference between ZA FAST-SIL and a liquid RTV2 silicone?

FAST- SIL ZA has putty consistency and can be broken, modeled and applied manually. A liquid RTV2 silicone is instead poured over or around the model. The choice depends on the geometry of the piece and the method of making the mould.

What's the mixing ratio?

BASE and CATALYST mixed in the ratio 1:1using equal amounts.

How long do I have to apply?

At 23 ° C, the working time / Pot Life declared by the manufacturer is approximately 3 minutes.

How long before ZA FAST-SIL hardens?

At 23 ° C, the curing time is approximately 12 minutescalculated from the beginning of mixing the two components.

How hard is he after vulcanization?

After 24 hours at 23 ° C, the declared hardness is 38 Shore A.

Can it be applied to vertical surfaces?

The putty-type consistency allows manual positioning and modelling of the material without the flow behaviour of a liquid silicone. Actual applicability should be evaluated according to model geometry.

Can metals be poured into molds made from ZA FAST-SIL?

Zhermack explicitly mentions the use of moulds for Metals with low melting temperaturelike pewter and other low melting-point fusion alloys. The declared temperature range for vulcanised silicone must be respected.

Vaseline oil can affect vulcanization?

Yeah. The manufacturer states that grease oil can inhibit the product and recommends a preliminary test.

The following video shows the use of Mark Plus, a silicone with similar putty consistency as the general application method. The video has a demonstrative character and does not present ZA FAST- SIL product.

What is the mixing ratio?

Base : catalyst ratio (by weight): 100 : 100.

What is the material's hardness?

Hardness after 24 hours: 38 ± 3 Shore A.
