ULTRAFAST TOOLING RESIN
From Plug to Mould with tooling resin Zero shrinkage

  • User Friendly, one component system
• Fast, make a mould in one day
• Zero shrinkage, on the cured laminate
• Produces tough, durable, long life moulds
• Pre accelerated resin with fillers added
• Performs like a normal laminating resin
• Rapid cure gives rapid mould making
• Perfect surface replication on the cured laminate
• Colour shift indicates when the laminate is cure
• Speed of production cuts mould making costs
• Longer life than conventional GRP moulds
• Complete dimensional stability
• Normal resin storage life without filler settlement
• Vinyl ester resins & gel coats available for enhanced performance
     
 

Norester? RM 2000/50 is a specially formulated, unsaturated polyester resin designed to produce long life, high quality moulds for the fabrication of thermosetting composite parts.
The single component, pre-accelerated, filled resin will cure at room temperature to produce a zero shrink mould without fiber print through. With the rapid cure and ease of handling of RM 2000/50, moulds can easily be produced in a single day.

By careful selection of the filling elements in RM 2000/50, the normal shrinkage which occurs with standard tooling resins is counter balanced to give a final mould cure which does not shrink retains the exact dimensions of the plug, with perfect surface reproduction.
     
  APPLICATIN RECOMMENDATIONS
Workshop Conditions
In order to achieve the necessary level of cure with Norester? RM 2000/50, the workshop must have a minimum temperature of 15oC, ideally 18-25oC. Above 25oC, we recommend the LGT version.
If the temperature is too low the optimum cure and zero shrink properties will not be achieved.

1 Preparation The surface of the plug must be free from voids and defects, with a propriety release agent applied.

2 GEL COAT Nord isophthalic tooling gel coat GC 200/201 is recommended for optimum tool life. For enhance durability GC 206/207, vinyl ester gel coat should be used.
Both are available to spray or brush and can be supplied in black, blue and green. Gel coat thickness should be between 600 and 800 microns. The gel coat must be fully cured before any reinforcing layers are added.

3 Norester® RM 2000/50 Application & Catalyst
Before use, mix the resin well, to achieve a homogeneous product.
Catalyst MEKPO must be used to catalyst Norester® RM 2000/50. Typically 1 to 1.25% should be used for optimum cure. Using more than 1.25% or less than 1% Calyst MEKPO will result in poor cure and laminate properties.

First Layer
In any laminate it is important that the first reinforcing layers are fully consolidated with all the air removed. Depending on the required performance of the finished mould the first layer can be :

1 x 200 or 300 gr/m2 chopped strand mat (emulsion bound) with the resin Norester® RM 2000/50
• A surface tissue or 1 x 200 or 300 gr/m2 chopped strand mat (powder or emulsion) with resin ISO-NPG Norester® 568
• A surface tissue or 1 x 200 or 300 gr/m2 chopped strand mat (powder or emulsion) with vinylester resin Norester® 680
When using a first layer with Norester® 568 or Norester® 680, these should be fully cured before backing up with Norester® RM 2000

     
 

4 Norester® RM 2000/50 Laminate
The Norester® RM 2000/50 is a low viscosity, easily consolidated resin which operates at a 4:1 resin glass ratio. After the first reinforcing layer has been put down 3-4 layers of 450 gm/m2 chopped strand mat can be laminated, or 1,300 – 1,800 gm/m2 of resin and glass sprayed down. The maximum amount of glass fiber which can be put down and easily handled before curing is 2,100 gm/m2

After the first laminate is cured and has cooled a further 1,800 – 2,100 gm/m2 can be laid down to build mould thickness if required.

5 Curing Norester® RM 2000/50
The Norester® RM 2000/50 is a fast curing resin system with a sharp gel point. When the laminate starts to cure a temperature rise to 50-60oC will be noticed and the colour will change from a mid brown to a lighter white/brown colour.
When cure is complete and the laminate has cooled, a second layer can be applied and so on.

6 Mould Stiffening & Reinforcing Elements
Stiffening and reinforcing ribs can be added to the back of the mould as with any composite mould. These can be laminated in as soon as the mould is fully cured and has returned to room temperature. This will not cause any deformation to the mould surface. It is not, therefore, necessary to wait 2-3 days for the mould to post cure.

Mould Life & Material Selection
The life of any mould depends on how well it was made, the materials used and the treatment it receives during it’s working life. Any recommendations can, therefore, only be indicative. However, from experience with our customers we can give indications of typical lifts (mouldings), which can be achieved with the various Norester® RM 2000 systems. These are :

Isopthalic gel coat up to & Norester® RM 2000 250 mouldings

Vinyl ester gel coat more than & Norester® RM 2000 250 mouldings

Vinyl ester gel coat, vinyl ester 1st layer up to & Norester® RM 2000 1,000 mouldings

All these recommendations are based on tests made in our laboratory and from experience with customers. Each batch of Norester® RM 2000 is carefully tested and approved before dispatch. It is the responsibility of customers to ensure that products made with Norester® RM 2000 are suitable for the application intended.
