Our position

We supply Sekisui tapes and materials through qualified channels. We do not claim to be an authorized distributor for every Sekisui product line in every region. Availability is confirmed at quotation.

Sekisui materials are often specified for electronics and specialty applications. We review the requested grade against the substrate, process and documentation requirement before quoting.

Material documentation is provided for the supplied batch where available. For tenders and regulated projects, confirm the exact grade and the documents required before approval.

Material families

Family	Typical use
Double-sided tapes	Electronics, display and general assembly
Foam tapes	Panel, trim and gap-filling bonds
Masking tapes	Processing and protection
Specialty tapes	Electronics and harsh environments

How we source

We compare the requested Sekisui grade with the application and available supply. If the exact grade is not available, we propose a qualified alternative and explain the difference.

Conversion is carried out in our Shenzhen plant when a slit roll, laminate or die-cut part is required. The quotation identifies the supplied material and the converting step.

What to verify

The quotation states the brand, grade and construction.
The batch label and delivery documents match the quoted material.
The documents supplied apply to the exact grade, not only the product family.
Any substitution is identified before production.
For regulated projects, approval is tied to the supplied grade and batch.

FAQ

Are you an authorized Sekisui distributor?

We supply Sekisui materials through qualified channels, but we do not claim blanket authorization for every line or region. Confirm the product and destination with us before relying on it in a tender.

Can you die-cut Sekisui material?

In many cases yes. We review the carrier, adhesive and liner, then confirm the cutting route and the achievable tolerance.

Can you compare Sekisui with tesa or 3M?

Yes. We can propose options from multiple sources with the available data so you can compare performance, documentation and cost.

Where these grades sit

What a Sekisui grade is usually specified for

Sekisui material tends to arrive on an enquiry as a part number already written into a drawing. This is what we then have to settle before it becomes an order.

Typical request	The question that decides the answer	What we confirm at quotation
A double-sided grade for display or bezel bonding	Whether the bond is over a foam step, a thin film or direct to the housing	The grade, its thickness range and the peel behaviour on your substrate
A foam tape for gap filling and trim	How much movement and compression the joint has to absorb over temperature	The core, the adhesive system and the compression set behaviour we can evidence
A masking grade for a process step	How long it stays on and what it must not leave behind	Removal window, residue behaviour and the edge quality after the cut
A specialty grade for harsh conditions	Which of heat, chemical or UV exposure is the real constraint	Whether the requested grade is the right one or a different family fits better
A die-cut part in a Sekisui material	Whether the carrier, adhesive and liner take the cut route without flowing	The achievable tolerance, the tooling type and the presentation to the line

Before a grade number goes onto your drawing

Check the number against the construction rather than the family name, since a family spans several adhesive systems
Confirm the destination market, because availability and channel scope are not the same everywhere
Ask which documents exist for that exact grade before the drawing is frozen, not after
Test on your own substrate with your own cleaning and dwell, then record the failure mode
Agree now what happens if the grade is restricted or superseded, so a substitution is an approval rather than a surprise
Say whether you are buying material, conversion or both; the two have different lead-time shapes

FAQ

Sekisui sourcing questions

Which Sekisui families do you hold?

The families that arrive on real enquiries: double-sided, foam, masking and specialty grades, with electronics and specialty applications the most common. Stock is held against demand rather than across a whole catalogue, so the grade you need is confirmed with the quotation.

Can you supply original material in converted sizes?

Yes. Slit and rewound rolls from the original brand material are a normal order, and the conversion is described separately from the material on the quotation so nothing is confused with a re-branding.

Is a Sekisui grade and its equivalent really interchangeable?

Sometimes, and only after the differences are named: adhesive chemistry, carrier or foam, total thickness, liner and how the part is removed. A cross-reference is a starting point for a test, not permission to swap.

Do you support a change if the grade is discontinued?

We identify the substitute before production with the differences that matter for your joint, and the change goes back to you as an approval event. What we do not do is ship something else and describe it on the invoice.
