Process Optimization With Moisture Controlled Calcium Carbonates

Typical solutions to manage moisture in reactive adhesives & sealants are the pre-drying of raw materials, use of heat & vacuum during mixing, and the addition of chemical drying agents, such as VTMO
Polyurethane, silicones and silane modified polymers are used to formulate systems that cure using ambient humidity and are known as moisture reactive adhesives & sealants. These tend to be high-end systems, especially with regard to their rheological and mechanical profile.
Water is critical to the performance of these systems, and the proper control of moisture during production and storage is often a challenge.
A mineral filler, such as Calcium Carbonate, is often the major component of these moisture reactive formulations, with addition levels reaching up to 60%. The large quantity of filler used can bring a significant amount of water into the system, which needs to be removed by either mechanical or chemical means.

Outstanding Performance Mineral for Reactive Adhesives & Sealants


Advantages of low moisture fillers from Omya
Lower mixing temperatures results in energy savings
Elimination of filler pre-drying means less production steps
VTMO reduction due to low moisture of filler
Independence from climate even in high humidity regions
Increased capacity due to shorter cooling times
