FAQ: Compliance & Supply Chain of 3M 6100 Series

Yes — 3M Scotch-Weld 6101 Off-White has been specifically tested and targeted for compliance with IEC 61249-2-21, the international standard governing halogen content (Cl and Br) in electronic materials. Explore more about Compliance & Supply Chain of 3M 6100 Series below.

• Halogen-free threshold: Cl ≤ 900 ppm, Br ≤ 900 ppm, total halogens ≤ 1,500 ppm
• This threshold is a required condition for materials entering Apple, Google, and Amazon Approved Material Lists (AML)
• 3M 6101 was specifically formulated for electronics applications where halogen content is audited

As an authorized 3M distributor in Vietnam, Prostech maintains and provides all required technical and compliance documentation for the 3M Scotch-Weld 6100 Series and ensures stable supply chain for the full series. Here is what each document covers and how to obtain it:

• Every COA from Prostech is traceable to a 3M manufacturing lot — providing the chain-of-custody audit trail required by Apple and Google procurement
• Prostech maintains -20°C cold chain storage — the COA reflects material that was handled correctly from 3M factory to your site
• Gray-market or third-party sourced material cannot provide this traceability — a COA from a non-authorized source is not accepted in AML audits

3M Scotch-Weld one-part epoxies are heat-activated materials — meaning the curing reaction is dormant until the material reaches the activation temperature. However, proper storage is critical to maintaining performance.

• Always check the lot number and manufacture date against the COA before accepting incoming material
• Do not use material where viscosity has doubled — this indicates expired pot life and the adhesive will not dispense or cure correctly
• Store syringes vertically, needle-end down, to prevent air pockets from migrating to the dispensing end
• Record thaw date and opening date for each syringe in production records

Why storage temperature matters — risk of improperly stored material:

• One-part epoxy slowly advances its cure state even at room temperature — this is the chemical mechanism that enables the material to cure with heat
• Material stored at room temperature for extended periods will show increased viscosity and reduced flow, leading to dispensing defects and inconsistent cure
• Improperly stored material may pass a visual inspection but fail adhesion testing — a quality risk that is invisible at incoming inspection without viscosity measurement

Yes. Prostech is an authorized distributor of 3M industrial adhesives in Vietnam, including the 3M Scotch-Weld one-part epoxy adhesive 6100 Series. Being an authorized distributor means:
