Reactive Diluents

Razeen® reactive diluents are monofunctional and difunctional glycidyl ethers that enhance flexibility, reduce viscosity, and contribute to the formation of cross-linked polymer networks in epoxy systems. Designed for solvent-free coatings and adhesives, these diluents offer improved wetting, better substrate adhesion, and customizable performance in a wide range of industrial and civil applications.

Solvent-Free Coatings
Improve flow, reduce viscosity, and adjust hardness in solvent-free epoxy systems
Flexible Adhesives
Enable elasticity and substrate wetting for structural and flexible bonding
Metal & Concrete Primers
Boost adhesion, film penetration, and surface tolerance in demanding primers
Civil & Industrial Flooring
Enhance workability and self-leveling in epoxy flooring with reduced VOC
Protective Coatings
Used in marine, tank lining, and pipeline systems to enhance chemical resistance and reduce brittleness under dynamic loads
Flow Modifiers
Serve as reactive carriers or flexibilizers in hybrid and modified epoxy systems, improving film formation and stress resistance

Razeen® reactive diluents are low-viscosity glycidyl ethers and specialty modifiers designed to adjust processing properties and film performance in epoxy systems. Available in mono-, di-, and tri-functional forms, they improve substrate wetting, reduce viscosity, and contribute to crosslinking during curing. These materials are especially suited for solvent-free coatings, adhesives, and flexible systems where reduced VOC, better flow, and elasticity are required.

Grades are manufactured under strict quality control and are compatible with a wide range of epoxy resins and hardeners, including amines, polyamides, and phenalkamines.
