Impregseal Your Plastic Moulded Connectors With Teknoseal Tsp 99

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.

One Sealant, Many Solutions - Tsp 99 Sealant by Teknoseal

Image
Porosity is a universal problem of all the manufacturers and industries face in the manufacturing of castings, powdered metal components, plastic components, and many more. Finest of leaks can render the components to be ineffective and inefficient . Impregnation sealant TSP99 is the solution to seal the micro-porosity leakages in metal castings, sintered parts, plastic electrical connectors, wood etc. Metal casting is an inevitable technique to meet the requirement of particular components for a number of applications ranging from fine machines to heavy ones. However, with the growing trend of light weighing products, the incidence of porosity has also risen. As porosity wrecks havoc on the supply chain with reduced efficiency and increased downtime, impregnation techniques with sealants have been widely accepted by manufacturers and foundries and recommended by design engineers globally. Exhaustive trials in various demanding applications prove the effectiveness of impregn...

What size of porosity can be sealed?

Image
Porosities Can Be Micro Or Macro In Size, Which Causes Gas Or Fluid To Pass Through. The Impregnation Sealant Is Only For Such Porosities And Not For Major Casting Defects, Casting Cracks, And Large-Diameter Blow Holes. A Porosity Is Like A Cobweb Structure And Not A Through-Hole. So, It Is Tough To Difficult The Porosity Size That Can Be Sealed. A Normal Thumb Rule Is That A Porosity Of Size 300 Microns Can Be Sealed. However, A Porosity Of More Than 300 Microns Can Also Be Sealed Depending On The Metal Structure And The Porosity Nature. The Porosity Size That Can Be Sealed Depends On The Method Of Retaining The Sealant In The Porosity. In Case Of Large Porosities, Some Procedures Exist To Retain The Sealant. If An Impregnation Chamber Is Completely Filled With Sealant And Heated, The Sealant Will Polymerize Into A Hard Plastic Of Two Meters’ Diameter. However, We Do Not Need To Seal Porosities About Two Meters In Diameter As They Never Exist. Following Are Some Unus...

Safeguard Your Assets | Applications of Teknoseal

A few of the typical applications of Vacuum Impregnation using Special Impregnation Sealant TSP 99 are listed below. Although there are several applications of the process, only a few of the more common applications are given. For further details please contact us and our application engineers shall be too glad to answer your queries. SAFEGUARD YOUR ASSETS Even minor leakage of gases, air or liquid can cause entire batches of production to be rejected. Impregnation as a de rigueur procedure, therefore, has received easy and complete acceptance among the people who are primarily responsible for the quality of products. Industries all over the world have experienced huge machining losses because leakages have been discovered after a casting has been machined. In such cases there is no choice but to scrap the casting. And if a casting is scrapped after it has undergone an expensive machine process, there is no way which that cast can be recovered. The solution is mandatory, pre-empt...
