PU Adhesive for Aluminum Windows & Door Corner Bonding
Two Component Polyurethane Adhesive for Aluminum Window and Door Corner Angle Frame Assembly with High Strength with Elasticity
 
∎Product Description
 
● PU2838 is a two-part adhesive based on Polyurethane technology. Fast-hardening, solvent-free, non-shrink polyurethane strong adhesive which, once hardened, transforms into a very strong-grip adhesive with excellent resistance to water, temperatures, weathering and ageing conditions. Excellent adhesion on metals. Due to the optimum filling properties, it is suitable for use in beading/cord applications.
∎Key Features
● Excellent adhesion on numerous substrates 
● Easy-to-use 
● Solvent free – Odourless 
● Weathering resistance according to DIN 204 D4 
● Resistant to ageing 
● Resistant to chemicals 
● Filling capacity: very good 
 
∎Typical Applications
● Bonding of corner connections in metal door, windows and facades as well as conservatories.
● Powerful bonding in metal construction; aluminium, stainless steel, galvanised steel.
● Powerful bonding of wood and derived wood products; chipboard, plywood, staircase renovation.
●Bonding of stone, natural stone, brick and ceramics
●Bonding of synthetic materials; PVC, fibre-reinforced plastics etc.
●Bonding of insulating materials including expanded polystyrene and polyurethane sheet
 
∎ 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.
