Traditional urea formaldehyde resin based adhesive for veneering and laminating operations including assembly work. With a choice of fast, medium or slow hardeners, you can accurately control assembly and setting times, or alternatively use filled hardeners to counteract adhesive penetration through thin or open grain veneers.

PREFERE 4152 flows easily on application and is applied by either brush or roller and being extremely versatile can be used with either hot or cold presses, bag press's or RF equipment. Easy to clean off application equipment after use with warm water. For use with most timbers, plastic laminates, veneers and boards.

Coverage: 100 to 150 grams of adhesive per square metre. 

Available in:

  • 5kg
  • 25kg

Overview

Prefere 4152 is used for small assembly applications in the furniture industry, it is also suitable for veneering.

Mixed with one of the filled hardeners Prefere 4152 gives a high viscosity and low-cost glue mix without the separate addition of fillers or extenders. These mixes are suitable for use in a variety of assembly applications and in conjunction with low-voltage or radio-frequency heating, for lipping and edge-banding. 

Prefere 4152 possesses good flow properties which allow low even rates of spread to  be obtained. It is easy to clean off after use - precipitated adhesive is not sticky and readily washes from spreader, rollers etc.


Preparation

Ensure that the surfaces to be bonded are smooth, clean and free from dust or other deposits. Plywood veneers, lippings etc. should be of uniform thickness. To avoid wetting difficulties that may arise through case-hardening it is good practice to sand plywood before gluing even though it may appear to have been sanded at manufacture.

For best results with Dynea resins, the moisture content of the surfaces to be bonded should be within the range 7-13%, but when pressing at temperatures above 105°C moisture content should not exceed 10%. Variation between the adjacent surfaces should not be greater than 3% moisture content.


Application

Application is usually by mechanical spreader, with the actual spread depending on the mix and surfaces to be bonded.

It is generally adequate to apply the mixture to one of the surfaces only. Using a mechanical spreader, spreads of 100 – 150 grams per square metre are obtainable.

Please refer to data sheets for Bonding Pressure, Hot Pressing, Heat Penetration and RF Heating.


Cleaning

Easy to clean off application equipment after use with warm water.

Storage

Dynea resins and hardeners should be stored firmly sealed in their original containers in a cool dry place (ideally 5 C – 20 C). Shelf life under these conditions is at least 6 months for Prefere 4152 and considerably longer for the hardeners.


Caution

DYNEA resins and hardeners are generally quite harmless to handle provided that certain precautions normally taken when handling chemicals are observed.

The uncured materials must not, for instance, be allowed to come into contact with foodstuffs or food utensils, and measures should be taken to prevent the uncured materials from coming into contact with the skin, since people with particularly sensitive skin may be affected. The wearing of impervious rubber or plastic gloves will normally be necessary; likewise the use of eye protection. The skin should be thoroughly cleansed at the end of each working period by washing with soap and warm water. 

The use of solvents is to be avoided. Disposable paper – non cloth – towels should be used to dry the skin. Adequate ventilation of the working area is recommended. These precautions are described in greater detail in DYNEA manual No. AD 2 Handling Precautions for Formaldehyde-based Products, Vinyl Emulsions and Hot-melt Adhesives and in Material Safety Data sheets for the individual product. These are available on request and should be referred to for fuller information.
