Request data sheet

Fluorescent, high viscosity, UV acrylic light-curing adhesive with excellent sterilization resistance.
Loctite AA 3943 is a clear to hazy, fluorescent, high-viscosity UV acrylic light-curable adhesive with excellent sterilization resistance. Can bond a variety of glass, plastic and metal parts that require environmental resistance. Suitable for assembly of disposable medical devices in accordance with Henkel's ISO 10993 protocol.
Compliant with Henkel's ISO 10993 protocol for disposable medical devices
Excellent adhesion to glass, plastic and metal
Designed for bonding stainless steel needle components, syringes and needles
Ideal for applications where large gap needles or catheters are to be used with adhesive prior to assembly, where the core needle hole is as minimally clogged as possible
Exceptional pin pull strength is achieved on most ferrule base materials, especially in high specification sizes

What you get with the material

We are not just shipping you a drum

A grade on its own rarely solves the problem. These are the four things we do around it.

Selection support

Tell us the substrates, the process window and the failure you are trying to avoid. We narrow the field before you order anything.

Process design

Prototyping and pilot runs

Bonded samples and pilot batches of 200–500 pcs on our own dispensing and curing equipment, so process questions are answered before mass production.

Prototyping & pilot

Cross-border supply, DDP

Destination clearance, local labelling and destination-language SDS are set up by us. Class-restricted goods are routed at quotation time, not discovered at the border.

Cross-border supply

Documentation chain

Which document, issued by whom, covering what, and notification when it changes. We pass manufacturer documentation through unchanged.

Material substitution

Common questions

Before you send the enquiry

Yes. Tell us the grade and how you intend to use it, and we will send the manufacturer’s current technical data sheet. We pass manufacturer documentation through unchanged rather than reissuing it under our own name.

No — and you should be careful with anyone in our position who says they do. What we supply is the document chain: which document exists, who issued it, what it covers, and notification when it changes. Compliance statements come from the manufacturer, not from us.

That is one of the most common reasons engineers contact us. Equivalence is a ladder, not a yes/no answer — some claims are backed by a matching data sheet, others only by chemistry family. We will tell you which rung a given substitution sits on before you commit to it.

Packaging sizes shown on this page are the standard units for this grade. Sample quantities for evaluation are handled case by case — tell us the trial you are planning and we will scope it with you.

Tell us what you are bonding

Substrates, process window, and the failure you are trying to design out. An engineer answers, not a form.

We do not issue compliance certificates. We supply the material, the manufacturer’s documentation, and the engineering judgement in between.
