Overview
What is AIRFORM FILL?
AIRFORM FILL is a flexible repair compound developed for conveyor belt repairs and is used for fast, permanent repair of damage on the belt. It contains no volatile organic compounds (VOC) and has a hardness of up to 60 Shore A. Belts that wear, tear or are punctured on the carrying strand over time are repaired with AIRFORM FILL.
AIRFORM FILL becomes touch dry about two minutes after application and can be sanded after about 30 minutes. These short waiting times shorten repair downtime: the application time of a repair product is directly linked to production downtime.
Its flexible, durable structure allows repairs without damaging the structure of the belt. The product is designed to withstand high temperatures and harsh chemical environments, and it simplifies belt repair and maintenance work in cement plants.
