Proper usage of TSP 99 fundamental to its reliability 600 (1)

Teknoseal supplies the TSP range of impregnation sealant. These sealants are used during the vacuum impregnation process to seal the micro porosities in various components.

The reliability of the TSP 99 sealant

The TSP 99 sealant range is very reliable because of its following attributes.

It has a working temperature range of -50 degrees Celsius to +220 degrees Celsius. It is completely stable within this range. It has very good washability, and hence there is no need of any after work or cleaning of machined castings, as in the case of complex and intricate machined castings with many tapped and drilled holes. It has very good penetration and adhesion due to which its porosity filling ability is exemplary. Due to its balanced viscosity it can seal both gross and fine porosities. Its stability in conditions of high vacuum enables sealing of extremely fine micro porosities in quick cycle times. Impregnated components are resistant to high pressure and vibrations.

Proper application of special impregnation sealant TSP99 is important to get the good result:

To get good results from impregnation with Teknoseal TSP99 impregnation sealant, it is very crucial to ensure its proper usage. Teknoseal provides technical and Material Safety data sheets and process application manuals which are useful in this regard.

For meticulous usage of this sealant, one must know the precise temperature range in which it must be stored. The effect of ultraviolet radiation and direct sunlight must be avoided. Teknoseal provides recommendations to its customers related to the storage conditions when the impregnation process is in progress and when the impregnation cycle is stopped for a few days. The material of the containers wherein the sealant is stored is also vital.

It is vital to avoid contamination of the sealant bath with oil, solvents and moisture and it is also important to agitate the sealant from time to time by degassing the same. Contamination of the sealant bath leads to imbalance of the viscosity of the sealant and also reduces its effectiveness in sealing performance and penetrability.

For impregnation to be effective, the sealant’s specifications must be within the acceptable limits. So, it is essential to carry out a few laboratory tests on a regular basis to confirm the suitability of the sealant bath for usage. Teknoseal can execute this testing at its technical center and provide detailed reports to customers as desired, to conclude if the sealant is fit for usage or not.

Impregseal your plastic moulded connectors with Teknoseal TSP 99

plastic impregnation 28_7

With the current trend of increasing use of plastics in automobile for weight reduction and increased electronics in vehicles, impregnation of electrical wire harnesses and plastic moulded connectors have gained much importance.

Wire harnesses are impregsealed against porosity. These wire harnesses are of different lengths, contain wires of different thicknesses, and are made by Tier 1 suppliers such as Delphi, ATPI, Siemens, Group Dekko, Sumitomo and Federal Mogul and many more.

The Reason we do it

As we know almost all molded or cast products consist of porosities, which contains micro voids. Impregsealing your plastics using TSP 99 completely fills these openings to moisture proof. The procedure is also called vacuum impregnating.

When it first emerged in the 1940s, porosity was sealed with sodium silicate and styrene-based resins, and it was mainly used to mend metal castings which were found to have “leakers” in leak-test operations. Shortly after the commencement, the method was used for preventing corrosion in metal castings, powdered-metal parts, and other porous metal elements.

Now the process of prevention of corrosion for other porous metal component such as plastic composites and wood, were being done with potting materials. But by the 1980s, more easily adaptable and flexible resins came to the market for sealing these products.

Wire electrical cables and individual insulated wires tend to have porosities within rubber and plastic insulation coating. When few insulated wire are adjacent to each other within wire harness, there are chances of sparking or short circuit between two adjacent electrical wires due to porosity in the insulation material. Hence it is an accepted practice to impregnate wire harness to avoid the situation.

Porosities in harnesses consist of micro porosities within the insulation coating. These porosities could be susceptible to trapping moisture that could lead to sparking and short circuit.

Low-viscosity impregnation sealant TSP 99 is effectively used to fill and everlastingly seal these minute openings in harnesses, which will prevent further corrosion and ensure long-term performance. TSP 99 requires heat up to 90°c to cure and this is a thermo-seal sealant.

The sealed up resin is a polymer that is flexible and durable. And it would never crack due to thermal expansion and has the power to endure common solvents such as glycol, oils, caustics and high uninterrupted operating temperatures up to 250°c

A procedure can seal the entire harness or just the tips or the ends. When the entire harness is sealed, it fills up the holes and gaps where wires touch the connectors or grommets.

The process involves impregnation of the wire harness vacuum impregnation machine. The wire harnesses are submerged into the sealant part and under the application of vacuum. The porosities are sealed using the Teknoseal TSP 99 sealant. After this impregnation is it is cured 90°c in hot water and impregnation sealant inside the porosities polymerizes and porosities are sealed.

The process of impregnation is very much needed in connectors. In the connectors, while the socket is made up of plastic, the internal pins are of copper and aluminium etc. In order to avoid the leakage path in the interface between the metal and plastic, impregnation is used, thereby making the components leak proof.

Wood is a versatile material having applications in industries like Pharmaceutical industry (Packaging), Marine industry (Ship Building); and waterproof applications in industries like Building and Construction for kitchen and bathrooms.

Wood is a porous material and has a lot of crevices. Germs and bacteria are formed in these crevices and porosities. When water or moisture seeps into these porosities, the germs and bacteria lead to fungal growth and eventual wood decay. Thus, wood rots if exposed to water and humidity for extended amount of time.

Impregnation of wood using TSP99 Sealant can prevent this and makes wood usable in various applications.

Water resistance for Marine applications
TSP 99 is used for Marine Plywood in Ship Building. Marine plywood is treated with chemicals to kill germs and thus to enable its usage in ships and bathrooms. As an alternative to this usage of chemical, wood impregnation process using TSP99 Sealant is done. Wood impregnation seals the crevices and porosities and entraps all existing fungi while preventing bacterial growth. Our sealant TSP99 is water resistant and is not affected by long exposures to water or moisture. It is the best way to give marine and water resistance to wood.

Improve machinability
TSP 99 is used for wooden door knobs. It is also used for improving machinability of wood and achieving smooth finish for objects and decorative pieces. It gives them body and solidity, along with enhancing the robustness and longevity of the showpiece. Impregnation provides a clean surface for wood, thus making it ready for high quality lacquering.

Avoid fungal growth for hygiene and health applications
TSP 99 is used in Pharmaceutical Industry for Wooden Palletization. Medicines which are exported over long sea travel are packed in wooden pallets, which must not have any contaminants such as fungus or bacterial matter. For safety and hygiene reasons, it is very important that the wooden pallet is free from fungi and bacteria. This purpose is served by the process of impregnation on the wooden pallet whereby all crevices and porosities are sealed using TSP 99 sealant which does not allow any fungal growth.

Applications in Home, Fencing and Ship Building
TSP 99 is also useful in Home Building and Construction. Marine plywood is generally used in modular kitchens and bathrooms. As it has a lot of moisture goes into the crevices which cause a fungal growth. We can impregnate this plywood to make it water resistant and thus prevent it from swelling. Thus it finds applications in building of ships, boats, canoes, oars, etc.

TSP 99 can be used as an effective replacement to Tanalith treatment for wooden fencing columns. As this impregnation material is not poisonous, using it in wooden fencing columns gives the required environmental resistance to wood, while preventing the probable hazards.

Thus, wood impregnation is an important and useful process in most of the applications of wood industry.
