Definition
Meaning
A specialized, high-strength, epoxy-based filler or adhesive compound used in metalworking and repair, which hardens to a very strong, durable state.

Linguistics
Semantic Notes
The term combines 'iron' (implying metallic strength and durability) with 'putty' (a soft, malleable material). It is a product name that has become a genericized trademark in some contexts.
Dialectal Variation

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation as 'железная замазка' which sounds odd. Use технический/эпоксидный герметик для металла or эпоксидная шпатлевка.

FAQ
Frequently Asked Questions
No. The name 'iron' refers to the iron-like strength of the cured material. It is typically an epoxy resin with metallic powders (like iron or steel) added for reinforcement.
While it will bond, it is over-specified and often poorly suited due to different flexibility and sanding properties. Specific plastic or wood fillers are better choices.
Iron putty is a subtype of epoxy, often with a thicker, putty-like consistency that doesn't run, making it ideal for vertical surfaces and gap-filling. It may contain more metallic filler.
No, it is exclusively a noun (a compound/product name). The action is 'apply iron putty' or 'repair with iron putty'.
