Lash adhesive extension glue

Selecting the correct drying speed is critical for retention. Beginners should look for a 3-5 second drying time to allow for placement adjustments, while advanced lash artists require a 0.5-1 second 'instant' bond to maintain high-speed application. Using a glue that dries too fast for your speed will result in 'dry attachment' and poor retention.

Most professional glues are based on Cyanoacrylate (Ethyl, Methyl, or Alkoxy). You must ensure the product is Formaldehyde-free and Latex-free to minimize allergic reactions. Always request an MSDS (Material Safety Data Sheet) and verify compliance with REACH (EU) or FDA (US) cosmetic regulations to ensure the safety of the delicate eye area.

Lash glue is highly sensitive to the environment. Most adhesives perform best at 20-25°C (68-77°F) with a humidity range of 45-60%. If your salon is too dry, the glue won't cure; if too humid, it will 'shock polymerize,' leading to brittle bonds. Look for 'Weather-Proof' or 'Wide-Range' formulas if you cannot strictly control your room climate.

For bulk orders, prioritize specialized nozzle designs that prevent clogging and triple-layer aluminum foil bags containing silica gel. An unopened bottle typically has a shelf life of 6-8 months, while an opened bottle must be replaced every 4-6 weeks to maintain optimal viscosity and bonding strength.

Lash glue is classified as 'Sensitive Goods' or 'Dangerous Goods' (Class 9) due to its chemical nature. You must ensure the supplier provides a Certificate for Safe Transport of Chemical Goods. Additionally, adhesives are temperature-sensitive; avoid long-duration sea shipping in summer months without climate control, as extreme heat can cause the glue to polymerize (solidify) inside the bottle during transit.

Look for 'Audited Suppliers' on Made-in-China.com who have undergone on-site inspections by third-party agencies like SGS or Intertek. Check their production capacity and R&D capabilities to ensure they can provide consistent batches, as 'white-label' glues from non-specialized factories often suffer from inconsistent chemical stability.

Never place a bulk order without a sample test. Negotiate for a 'Sample Kit' that includes different drying speeds. For bulk pricing, aim for a 15-25% discount on orders over 500 units. Discuss Private Label (OEM) options early, as custom bottle molding and label printing can add 10-15 days to the standard lead time.

Use Secure Payment services provided by Made-in-China.com to ensure your funds are protected until the goods are shipped. Clearly define the Incoterms (e.g., DAP or CIF) in the contract and include a clause for compensation or replacement if the glue arrives separated or polymerized due to improper packaging by the manufacturer.
