WEICON Easy-Mix PU-90 / PU-240

fast - strong - reliable

High-strength, fast-hardening 2-component structural adhesives based on polyurethane with excellent adhesion on a broad range of materials. The high-viscosity formulation enables application even on vertical surfaces. The 2-component system also provides for fast and controlled curing. This makes the adhesive bonding process virtually independent of layer thickness, humidity and ambient temperature.

The following materials can be bonded among themselves or to each other with a high tensile, shearing and impact strength:

Fibre composite materials (e.g. EP-GRP, UP-GRP, CFC, SMC and fibreglass)
Plastics (e.g. PVC, ABS, PMMA, PC and phenol)
Polyurethane, epoxies and polyester
Steel, aluminium and stainless steel
Wood, ceramic, etc.

WEICON Easy-Mix PU-90/PU-240 adhesives are characterised by the following properties:

Fast initial strength
Immediate adhesion even on vertical surfaces, no dripping, can be modelled
High tensile, shear and impact strengths
Permanently elastic/impact resistant, low shrinkage
For indoor and outdoor use
Resistant to weathering and chemicals
Can be sanded and painted over after approx. 30 minutes
Neutral to materials
Temperature resistant from -55°C (-67°F) to +125°C (+257°F)

WEICON Easy-Mix PU-90/PU-240 adhesives are suitable both for universal use in dynamically loaded adhesive bonds and for applications where a high flexibility is required. They are used in the following industrial sectors:

Plastics technology
Mechanical engineering
Model and mould construction
Ship and boat building
Energy systems and electrical engineering
Metalworking
Car body and vehicle construction
Trade fair and exhibition construction

Processing:

The conditions for proper adhesive bonding are clean and dry surfaces (e.g. after cleaning and degreasing with WEICON Surface Cleaner). Best results are achieved if the adhesive surfaces are mechanically roughened. Some low-energy adhesives, especially PTFE and polyolefins, etc. can only be bonded after special pretreatment of the surfaces, e.g. with fluoridation, low-pressure plasma, corona, flame impingement, etc. The adhesive is applied on one side.
