LRBG Chemicals USA UF 313 is a melamine-fortified, internally catalyzed urea formaldehyde powder adhesive designed for the tapeless splicing of veneers with straight-through and cross-feed conventional as well as high-speed splicing machines. LRBG Chemicals USA UF 313 is formulated for applications requiring durability, light color and opacity, and moderate-to-high speed operation. It is characterized by a large operating window, allowing application of the adhesive one day and bonding up to two days later.

Application Procedure

Although UF313 contains an internal lubrication package, release properties can be further enhanced where needed through the addition of up to 2% of RA -10 release agent. Glue line color can be fine tuned through the addition of W - 10 Whitener or BR-10 dye (brown).

Mixing Procedure:

  • Best results are obtained with a mix containing 50 parts of water and 100 parts of UF 313 adhesive. To get a lump-free mix, add the powder adhesive to the mixing pot, follow with the water and immediately start the mixer.
  • The water temperature should be 15 - 25°C. Mix the blend for at least 5 minutes. Add the adjustments (release agent - typically 2 parts, whitener - typically 1 part, or dye - typically a few drops) if needed and remix for 2 minutes.
  • If the mix is not to be used right away, store it in a closed vessel or cover the vessel with foil or plastic wrap to prevent water loss by evaporation. Up to 8 parts of additional water may be used to thin out the mix if needed.
