Обзор продукта
LOCTITE 409 is a one-component gel-viscosity cyanoacrylate instant adhesive formulated for applications where larger bond gaps (~0.15 mm) exist and flow-control is important. Its gel consistency prevents run-off on vertical or irregular surfaces, making it suitable for bonding metals, rubbers and many plastics—including difficult-to-bond polyolefins (with primer). This versatile adhesive delivers rapid fixturing in seconds, enabling fast assembly of components requiring reliable bonding.
Основные характеристики и преимущества
-
Gel-viscosity formula prevents adhesive migration on vertical or irregular surfaces.
-
Bond gap capability up to ~0.15 mm (0.006″), accommodating slightly mis-fitted parts.
-
Rapid fixture time (approximately 20–60 seconds) for efficient production or repair.
-
Strong adhesion to metals, rubbers and many plastics (with primer for low-energy plastics).
-
Clear cured appearance, excellent for visible assemblies requiring aesthetics and strength.

Инструкции по применению
Подготовка поверхности: Clean both bonding surfaces thoroughly—remove grease, oil, dust and old adhesives. Use a suitable degreaser (e.g., LOCTITE® SF 7070) if necessary.
Применение: Apply a small amount of LOCTITE 409 to one surface, keeping layer thin for best quality.
Assembly: Bring parts together immediately, achieve correct alignment, and hold until fixtured (approx. 20–60 seconds).
Затвердевание: Although handling strength is achieved quickly, allow full 24 hours cure for maximum strength.
Разборка / ремонт: For parts requiring disassembly, refer to manufacturer’s guidelines—locally applied heat or mechanical removal may be needed.
Совет: For low-surface-energy plastics (PP, PE, PTFE), use primer LOCTITE® SF 770 to enhance bonding.
Часто задаваемые вопросы
Q1: Why does LOCTITE 409 recommend a primer for some plastics?
A1: Because low-surface-energy plastics (such as PP or PE) do not allow cyanoacrylate adhesives to wet and cure properly without a primer like LOCTITE SF 770.
Q2: Can it be used on vertical surfaces without dripping?
A2: Yes—it’s a gel formulation that resists flow and sag on vertical or uneven surfaces.
Q3: What is the typical fixturing time?
A3: Approximately 20-60 seconds under typical conditions.
Q4: What bond gap can it handle?
A4: Up to approximately 0.15 mm (0.006″).
