Minimum film-forming temperature, glass-transition temperature and a finished mortar’s service conditions are not interchangeable. A single polymer temperature number cannot approve the whole construction system.
Identify what the supplier actually measured
The WACKER VINNAPAS 5044 N (GER) sheet lists a minimum film-forming temperature with a specified method. It does not turn that value into a universal lower application limit or upper service limit for every mortar. Ask for the offered grade’s actual method and property definition.
MFFT concerns formation of a film under the stated test. Tg describes a polymer transition under its measurement conditions. The required performance of a formulated and cured mortar depends on a different system and test context. If a document uses only “temperature resistance,” ask what outcome and conditions it means.
| Reported item | Decision it cannot settle alone |
|---|---|
| MFFT | Whether the complete mortar can be applied under all site conditions |
| Tg | The finished construction system’s full performance range |
| Service test | The cause of every polymer-level difference |
Use application evidence for the application decision
Define the intended application and exposure conditions with the technical team, then assess the complete formulation against the relevant acceptance criteria. Do not infer years of durability or a universal temperature range from one raw-polymer descriptor.
Send ENVO the grade currently used, formulation type, relevant temperatures and required measured properties. Request available supporting information for the offered grade. Keep a published characteristic, a trial result and an agreed commercial claim as separately labelled evidence.
