Astro Celrez LPM Series

Description

The Astro Celrez LPM series are liquid, melamine-formaldehyde resins.

Application

Astro Celrez LPM are thermosetting resins that can be used in paper-saturating applications for the manufacture of low-pressure melamine laminates and laminate flooring products. To achieve adequate cure response, the use of a latent acid catalyst (i.e. Aricel AS-32 or Fentak CT0234) is recommended.

Benefits

Laminates produced with Astro Celrez LPM resins exhibit good water and craze resistance, hardness, gloss, and clarity. Astro Celrez LPM provides good paper penetration properties and excellent cure response when properly catalyzed.
