Depending on the foundation of the adhesive or sealant, numerous types of raw materials are used to produce adhesives and sealants.
Water-dispersion adhesives, wood, acrylic sealants, dispersions and starches, and dextrin are commonly utilized in aqueous systems.
In two-component polyurethane and epoxy systems, polyols, catalysts, and hardeners are utilized; they have an impact on the mixture’s pot life, rate of curing, and final qualities.
Antioxidants that shield hydrocarbon resins from oxidation are a crucial component in the manufacturing of hot melt adhesives.
Silanes are also widely used as crosslinking agents, water scavengers, and adhesion promoters.
The MS prepolymer, which is used for a variety of adhesives and sealants in construction, is the most promising binder that combines the qualities of silicone and polyurethane binders.
Building sealants benefit from UV absorbers and HALS-, which improve their weather resistance.
Adhesives and sealants with biocides have longer shelf lives and don’t develop mold while being used.
In silicone sealants for construction, vinyl liquid and silicone oil are frequently employed.
All kinds of adhesives and sealants use rheological additives, dispersants, defoamers, and fillers to speed up production.
