L'ho usato per sostituire una guarnizione che non veniva più prodotta di una caldaia per ferro a vapore e devo dire che funziona molto bene a temperature oltre i 100°C ed a qualche bar di pressione l'unica pecca se la vogliamo così definire sono i tempi di indurimento del prodotto che vanno oltre le 24 ore a temperatura ambiente ma a parte questo fa veramente il suo lavoro

Para el uso que yo l e he dado, es más que aceptable y suficiente. No lo he usado para nada completo del motor del coche ni nada del estilo, por lo que la resistencia térmica en ese aspecto no sé como será. La he usado para sellar partes externas del coche y para fijar alguna goma y para ello muy bien. Cumple perfectamente. En cuanto al uso, es bastante viscosa, un poco engorrosa de usar. Recomiendo tener a mano agua con jabón porque se acaba pringando todo.
