Aerolite UP4145 One Shot Adhesive
One-component urea powder adhesive
Description
Aerolite UP 4145 is a one-component urea powder adhesive, which only requires mixing with water to make it ready for use. It is suitable both for industrial use as well as for smaller bonding operations. It is especially suitable for joinery, cabinetwork and assembly gluing, particularly when small amounts of glue mix are needed, or when demand is such that the use of a liquid adhesive is uneconomic.
Bonds obtained with Aerolite UP 4145 are of durability class C3 according to EN12765.
The setting time of Aerolite UP 4145 is fast, but will allow adequate working life for most envisaged applications using hot and cold pressing techniques.

Use a dry, preferably non-metallic container, and add water to the powder gradually, stirring to ensure the powder is evenly mixed. Continue to stir until the solution is free from lumps. The mixed adhesive is ready for use. To ensure that a consistent glue mix with the correct properties is obtained, mixing by weight is strongly recommended. Addition of too much water will seriously reduce the rate of setting and the gluing properties, particularly at low temperatures.

Glue Spread
Apply glue mix thinly to one surface, then assemble the joint and apply full clamping pressure. If only light clamping pressure is used, the glue mixture should be applied to both surfaces to be joined.
Normally the adhesive spread is in the range of 100 – 400g/m2 .
