Those who want to get rid of the hydrolysis products such as styrene and propylene glycol (apparently the culprits of osmosis) might try a homemade Hotvac
. It's a tedious process as I've got only two heating
mats but we are very happy with it and it works nicely (a total drying per square meter takes between 5 to 10 hours).
What's convenient about the custom made mats: The RAYCHEM self regulating heating
cable sealed within the RPDM rubber mats heat resistant never exceeds (even partly) the max. temperature of 110°C (depends on the cable you choose, of course).
