100% black silicone that is vivarium, terrarium and aquarium safe once fully cured.
Avoid direct inhalation and contact of the silicone while it is still wet. Please wear appropriate VOC ventilation mask, glasses and gloves when handling uncured silicone.
Please allow 7-14 days to fully cure before adding any plants or animals to your newly built enclosure. If you still smell “vinegar” please allow more time to cure. You can mist the silicone with water once dry to help speed up the curing process.
