Key Features
Aesthetic + protective seal for MS battery casings
The Black Binding Sealing Tape is used to cover the waterproof sealant within the MS case, improving the battery's aesthetic appearance.
Manufactured under an ISO 9001:2015-certified quality management system.
Black Binding Sealing Tape is used to cover the waterproof sealant within an MS (mild steel) case, improving the aesthetic appearance of the finished battery. On a sealed casing the sealant bead is applied along the joint for function rather than looks: it is uneven, it collects dust and it shows every mark left by the applicator. A binding tape run along that joint covers the bead, gives the seam a clean, deliberate black line, and provides a consistent finish across every unit that leaves the line. It is the last material applied to many battery casings, after the sealant has done its job, and it is the part of the assembly the end customer actually sees. Black Binding Sealing Tape is manufactured by Lalit Jain Industries Pvt. Ltd. (LJIPL), an ISO 9001:2015 certified adhesive tape manufacturer founded in 1987, at its units in Rai, Sonipat (Haryana) and Bawana, Delhi NCR, India.
It is used to cover the waterproof sealant within the MS case, improving the aesthetic appearance of the battery. MS stands for mild steel, the material many battery enclosures are built from.
The sealant that waterproofs a casing joint is applied for performance, not appearance. It leaves an uneven bead, and that bead is usually visible on the outside of the finished unit. Running a black binding tape along the joint covers it and turns an irregular line into a straight, uniform one.
The result is a consistent finish on every unit that comes off the line, which matters when the enclosure is the part a customer sees. Enclosures that also need protecting from scuffs during handling and transport are often covered with Prateek® surface protection film from the group range.
Two reasons, and only one of them is cosmetic. The visible one is finish: a sealant bead reads as unfinished work, however well it performs, and it varies from unit to unit depending on how it was applied.
The practical one is that an exposed bead is a surface that collects dust and shows handling marks before the product even reaches the customer. A tape laid over it gives a uniform, wipeable black line instead.
Because the tape is applied after the sealant has cured and is doing its job, it is a finishing operation rather than a sealing one.
Near the end. The casing is assembled, the waterproof sealant is applied into the joint, and the binding tape is then run along that joint to cover the sealant and tidy the seam.
That position in the sequence is what defines the product requirements: it must lie straight, cover consistently, and look like a deliberate design line rather than a repair. Send the width of the seam you need to cover with your enquiry, and the requirement will be quoted against your specification.
The casing finish is the final step of a pack build; the EV battery tapes hub covers every layer that goes in before it.
The tape is run along the sealed joint of a mild steel casing to cover the waterproof sealant. What was an uneven bead becomes a straight black line, and the finished unit looks deliberate rather than unfinished.
Sealant application varies slightly from operator to operator and unit to unit. A tape does not. Covering the bead with binding tape gives the same seam appearance on every enclosure leaving the line, which is what makes the finish repeatable.
The enclosure is the part the end customer sees. Improving the aesthetic appearance of the battery is the stated purpose of this tape, and covering the sealant is the specific way it does it, at the end of the assembly sequence.
It is used to cover the waterproof sealant within the MS case, improving the aesthetic appearance of the battery. The sealant is applied for waterproofing and leaves an uneven bead along the joint; the binding tape covers that bead and turns it into a clean, straight seam line.
MS stands for mild steel. An MS case is a mild steel enclosure, the construction used for many battery casings. The joints of such a casing are sealed with a waterproof sealant, and this tape is applied over that sealant as a finishing step.
No. The waterproof sealant within the MS case does that. The tape is applied over the sealant, and its stated purpose is to cover it and improve the aesthetic appearance of the battery. It is a finishing operation performed after the sealing is complete.
Black reads as a deliberate design line along a seam and hides the irregularity of the sealant bead underneath. It also keeps the seam looking uniform across every unit, which an exposed bead cannot, since application varies slightly from one unit to the next.
Near the end. The casing is assembled, the waterproof sealant is applied into the joint and does its job, and the binding tape is then run along the joint to cover it. Send the seam width you need to cover when you enquire so the correct width is quoted.
