Features & Benefits

CASE Ingredients Features

Low Viscosity

Properties

Due to the low viscosity and the full crystallization resistance Razeen® P LR 2257 is a most suitable epoxy resin in formulating solvent free systems yielding,

• Very good processing properties
• Good mechanical performances
• Good surface penetration
• Medium chemical resistance / good acid and solvent resistance

Solventless & High Solids Coating

Industrial Additives End Use

Cement

Application

Razeen® P LR 2257 can be cured with polyamines, polyamidoamines or their adducts for solvent-free coatings, self-leveling and mortar floors, concrete injections, structural adhesives, trowelling compounds and impregnation systems. In combination with unmodified epoxy resins, like Razeen® P LR 1150 and Razeen® P LR 1100 the viscosity of the end formulation can be reduced.
