One Component Polyurethane Adhesive Sealant for Aluminum Window Building
 
∎Product Description
 
● Polyurethane Adhesive Translucent PU-1838 is a one-part, fast-hardening translucent, solvent-free moisture curing polyurethane adhesive which, once hardened, transforms into a very strong-grip adhesive with excellent resistance to water, temperatures, weathering and ageing conditions. Due to the excellent filling properties, it is suitable for use in beading/cord applications.  
● PU-1838 Designed for water-resistant bonding of wooden elements where a fast mechanical hold is necessary (10 minutes of clamp hold at room temperature) in order to permit working of hand-manufactured articles. 
Suitable for structural strong-grip bonding of wooden elements on both porous and non porous substrates. Particularly useful and practical for high mechanical resistance assembly and outdoor applications.

∎Packing Specification
● PE Cartridges 300ml,  
● 24pcs per box.
● Color :  Translucent
 
∎ Instructions 
●All surfaces to be bonded must be perfectly clean, dry and free from dust, grease, oils and debris. 
●Cleaning of non-porous substrates using a lint free cotton cloth and organic solvent. Cleaning of porous substrates using a steel wire brush to remove loose particles. 
●Apply PU-2838 on one side with the special caulking mixing gun and assemble parts immediately or within the processing time. 
In hot weather conditions the pot life time is reduced and consequently the processing time 
must be quicker. Please carry out some preliminary test before starting your bonding session. 
The high viscosity holds elements to be bonded in position, the use of clamps however sometimes is 
recommended. 
Application
●Weathering resistant bonding of corner joints on metal windows, doors, façade as well as conservatories. 
●Suitable for structural strong-grip bonding of wooden elements on both porous and non porous 
substrates. Particularly useful and practical for high mechanical resistance assembly and outdoor 
applications.
