Send us the part and the problem. An engineer takes it from there.
Every “Talk to an Application Engineer” button on this site lands here. Tell us what you’re assembling, where it has to be made, and what’s going wrong — the reply comes from someone who designs adhesive joints, not a sales desk.
No account, no obligation, no add-to-cart. Describe your problem in the form below, or reach us directly by email, phone or message.
• CT_01 // REACH US
Three ways in. All of them reach a person.
Pick whichever suits how you already work. The form below is the most thorough — but a one-line email or message is a perfectly good place to start.
cs@assembtek.com — best for detailed specs, a drawing, or a datasheet you want us to look over.

• CT_02 // TELL US WHAT YOU’RE BUILDING
The more you tell us, the sharper the first answer.
Start by telling us who’s asking — the form adapts to what we’ll actually need from you.
Who’s asking?
You’re choosing, qualifying or scaling an adhesive for a real design.
Have this ready
- The two surfaces you’re bonding (substrates, housing, coatings)
- What the joint has to survive — heat, drop, humidity, chemicals
- Cure or throughput limits (line speed, oven, UV)
- Any current candidate, and what’s wrong with it
You need supply, a compliant equivalent, or documentation.
Have this ready
- The product you use today and who makes it
- Volumes and destination plants / countries
- The document you need — TDS, SDS, RoHS, REACH
- Why you’re re-sourcing (cost, EOL, lead time, dual-source)
You’d like to carry or co-sell the lines we integrate.
Have this ready
- Your market and the regions you cover
- Brands and product lines you already handle
- The customer segment you serve (industry, size)
- What you’re looking for from a partnership
Something else — press, careers, a general question. That’s fine too.
Have this ready
- What you’re getting in touch about
- Enough context for us to route it to the right person
- How you’d prefer we reply
• CT_03 // BEFORE YOU SEND
A few things people ask first
The essentials: the two surfaces you’re bonding, what the joint has to survive (heat, drop, humidity, chemicals), rough volumes, and where it’s being built. Don’t worry about getting it complete — we’ll ask for the rest.
Yes. We’re vendor-neutral, so the first step is understanding what you run today and why. If it’s working, we’ll say so — we only suggest a change when there’s an engineering reason for one.
Yes, on request — before you share drawings, specifications or anything sensitive. Just mention it in your message and we’ll send one over.
Both. We’re authorized distribution for lines like Henkel, Loctite and 3M as well as proven domestic brands, plus the engineering to match the right one to your process — recommending and supplying are one conversation here, not two.
Straight to an application engineer — not a ticket queue. You’ll normally hear back within 24 hours on business days. The team is in Hong Kong, GMT+8.
Still deciding what to ask?
Send the part, the process step, and where it has to be made. We’ll tell you what else we need — and whether it’s something we can help with.
