UZIN KR 430 Premium Pro – 2-Component PU Adhesive

Two-component reaction resin

UZIN KR 430 is a 2-component polyurethane adhesive ideal for the installation of all types of floor coverings that demand reliable bonding in extreme conditions. Suitable for floor covering installations subject to heavy use and rolling loads, UZIN KR 430 cures to an extremely high final strength and hardness with excellent resistance to plasticizers, surface moisture and temperature exposure.

  • Topical moisture resistance • Excellent for use in high moisture areas (bathrooms, building entrance vestibules)

Technical data

*At 70 °F (21 °C) and 65 % relative humidity. Lower temperatures will increase pot life and working time, while higher temperatures will reduce them. Coverage is approximate and may vary depending on substrate porosity and angle that trowel is held. Flash time, is the waiting time required before installing flooring. Working time, is the window of time for the adhesive to accept flooring. Note: Flash time and working time may vary based on temperature, humidity, substrate porosity, trowel size and jobsite conditions.
