The HDG process is a metallurgical reaction that bonds zinc to steel. Parts are dipped in a bath of molten zinc at around 450°C. This creates a thick, durable, multi-layer coating of iron-zinc alloys that provides superior corrosion protection, particularly in harsh environments.
Adhesive coatings under this standard are typically rated for service temperatures between -60°C and +150°C (higher for specialized "hot" engine applications). din 26727 pdf hot

The standard specifically details the functional properties of . This microencapsulation process is key: the adhesive is applied to the threads in tiny, inactive capsules. Only during the screwing process do these capsules rupture, releasing the adhesive, which then cures to lock the threads securely in place. Adhesive coatings under this standard are typically rated
