"Viksint PC-68": specifications, manual, reviews

"Viksint PC-68" is a composition of a viscous fluid which consists of SCTN (low molecular weight rubber and catalyst). The product belongs to category electrical insulating compounds and sealants.

Description

"Viksint PC-68" made in Russia, and is designed to protect against corrosion, cold, heat radio and electronic devices that operate at high humidity and temperatures from -60 to 200 degrees. The sealant is very flexible, soft, pliable. Well-insulates product from permalloys and ferrites. The material protects the equipment and items made of brass, tin, aluminum from corrosion and does not cause it. The compound is transparent, it can be easy to do the repair schemes and units.

The Main objective of all sealants in fixation of the structural components of electronic devices. The compounds not only record but act as a sealant. Modern silicone materials combine these two functions, they are divided into acrylic, urethane and others, depending on the basics.

Silicon in its properties - the most reliable sealants. They are used in electronic devices. When choosing a compound it is important to consider their characteristics, including adhesion, temperature, elasticity, thermal expansion coefficient, strength and neutrality.

Neutral sealants do not emit corrosive substances that do not cause corrosion. Their peculiarity lies in the fact that the compounds perform their functions under a variety of conditions, including radiation, the environment, pressure and humidity.

Instructions

Compound "Viksint PC-68" - pouring silicone sealant. To use the material on purpose, to mix the catalyst №68 and the rubber SCTN (you can replace the pasta) in a metal container until smooth. The time of mixing the mass is from three to ten minutes depending on the intensity and number of components. Ensure there was no air bubbles and foam. When the compound is ready, apply it on the prepared surface with a spatula.

Maximum tightness occurs within four days from the moment of mixing of the catalyst paste. If you are using the sublayer P-11, the surface is degreased with acetone, ethyl alcohol, gasoline, and dry naturally in the sun. Then apply a dry brush sublayer evenly, to dry it for forty minutes and on top put "Viksint PC-68".

Features

"Viksint PC-68" - two-component product that consists of a base and catalyst. If it is mixed with a catalyst №68, it will be hard during the day. The compound is a rubber-based SCTN and transparent liquid. Consistency (hardener) may be totally colorless or have a light yellow color.

The technical characteristics of the material include:

• Sufficient viscosity (90-150 seconds);
• The strength of the bond of the sealant with metal (0.3 kg/cm);
• Elongation at break (110%);
• Strength (MPa 0,23);
• Electrical resistivity (1*1013 Ohms);
• Surface resistivity (1*1013 Ohms);
• Loss (0,0025);
• Permeability (3,0);
• Dielectric strength (15 kV/mm).

Its properties for the sealant keeps the air temperature from 0 to 30 degrees.

The advantages of the compound include transparency (it is easy to repair the units and circuits, doing fault detection), high dielectric performance, large temperature range of use of the sealant and the viscosity, elasticity and softness (good quality product), has excellent adhesion. After mixing, the compound becomes hard or rubbery. The underlayer helps to improve the adhesion (grip). Using "Viksenta" insulate not only the equipment but also the threaded connection tubing internal heating system of residential houses or businesses.

Price

Specifications "Viksint PC-68" fully comply with the regulations that apply to sealants. Compounds are delivered most often in the configuration of five to seven kg. the Average cost is 380 rubles per kilogram. Sealer is sold in more extensive package.

Reviews

Reliable or not silicone sealant "Viksint PC-68"? In the instructions from the manufacturer indicate what technical characteristics of a compound. Judging by the user feedback, thanks to the consistency and transparency of the sealer is easy to use and apply it. It does not stain hands or objects, and if this happens, the material is easy to remove to dry. The compound can withstand low and high temperatures, chemically resistant, insulates well.

It can be called universal, as it is used not only for sealing electrical and radio devices, but also for bonding glass, fabrication of transparent forms, isolation schemes. Sealant is recommended for use for devices that operate in conditions of vibration and humidity. Some users believe that the material is expensive for its category.
