Polyurethane Glue

PEGACRIL PU glue is a one-component elastomeric putty with a polyurethane base. This polyurethane glue polymerizes quickly on contact with the humidity of the air, it becomes a flexible and resistant cord that has a very good adherence to the vast majority of traditional building materials.

APPLICATION AREAS

PEGACRIL PU, polyurethane glue, is recommended for gluing various materials in industry and for making joints. Adheres without primer to most common materials: wood, anodized aluminum, polyester lacquered metal, concrete, glass, high pressure laminated (HPL) panels, fiber cement and porcelain panels, Vitroflex Wallguard, etc.

HOW TO USE THIS POLYURETHANE GLUE

But, you may be wondering how this polyurethane glue is used. Next, we give you a series of steps so that you use it in a very simple way:

PEGACRIL PU is applied with the help of a manual or pneumatic gun on clean, dry and degreased substrates, at temperatures between + 5ºC and + 40ºC. All traces of non-adherent greases, paints or coatings must be completely removed.
Let the surfaces dry after cleaning and degrease them. It is advisable to clean the concrete with a metal brush and sand the metal surfaces if necessary. Clean after sanding.
For applications below + 5ºC, store cartridges or bags at + 20ºC before use.
The cartridge is kept for 12 months in the original container stored at a temperature between + 5ºC and + 25ºC. Once opened, it must be used within 24 hours after opening.
After being applied, the two surfaces to be joined must be squeezed and the excess product removed with the help of a damp spatula.
During polymerization, avoid contact with MS polymers, hybrid polyurethanes or non-polymerized silicones, and also with alcohols or ammonia.

The performance of the PEGACRIL PU cartridge is considered:

Diameter (mm)	2	3	4	5	6	7	8	9	10
Cord length (m)	98	43	24	15	11	8	6	4	3

In very porous materials it is recommended to use a larger quantity.

This polyurethane glue has good compatibility with:
- Water-based paint.
- Solvent-based paint; trials must be performed.

Cleaning:

Instruments should be cleaned with xylene or toluene when the putty is not yet polymerized.
After polymerization, the only way to remove and clean the product is abrasion.
