Product Applications
  • Apply Rakol® GXL 4 thinly and evenly to one side or, if a high degree of water resistance is required, to both sides.
  • Lay the parts together within the open time and maintain the pressing pressure until the required initial strength is achieved.
  • The pressure should be high enough to achieve joint closure in the entire joint area (depending on the substrates used).
  • Woods containing resin require longer pressing times.
  • In accor- dance with the Quality Guidelines of i.f.t. Rosenheim, Laminated Profiles for Wooden Windows, the wood moisture content must be ( 13 ± 2) %.
  • The room tem- perature and the wood temperature must be at least 15 ℃.
  • Clean machines and utensils with water before the ad- hesive dries.

Compatibility Information

Due to the different composition of wood constituents, unpredictable discoloration may occur in individual cases with different types of wood. In addition, iron in combination with the tannic acid of the wood can cause color changes, especially in oak. We recom- mend carrying out your own tests. To avoid the risk of corrosion, we recommend using storage tanks, pipes and spreading equipment made of stainless steel or plastic (rigid PVC, polyethylene, polyester resin).
