PRECAUTIONS FOR QUEEN'S VEIL MOULDING

  1. Near the double curvatures, edges or corners, it is very important to work slowly & gently with the brush.
  2. Brush must be used should be short, Soft and White Hair for best results
  3. Templates of “Queen’s Veil” precut are very important for corners and contours extremely necessary for some curvatures and contours. Continuity of designs at joint is very important.
  4. Work slowly and gently with the brush in double curvatures, edges or corners
  5. Short, soft and white hair brushes must be used.
  6. While doing stippling with brushes start from the centre of mould in outward direction.
  7. As preferred by the moulder, clear gel coats can be used instead of clear first resin coat

Properties : Laminating properties are similar to that of fiberglass and Polyester Surfacing Mats in terms of Wet-out, Pliability, Drape, Glass to resin ratio and Porosity. The colours are compatible with polyester resins and will not smudge when laminating.

TECHNICAL SPECIFICATIONS FOR USING "QUEEN'S VEIL" FRP MOULDINGS USING QUEEN'S VEIL

  1. Polish the mould to the required extent to get the degree of finish required on the moulded product. E.g. glossy or matt.
  2. Apply Wax & PVA or any Release Agents.
  3. Apply a liberal coat of Roof light OR Clear GP Resin OR Gel coat (about 180-220 gms. per sq. mtr. )
  4. Allow the resin to gel to give a tacky surface.
  5. Place the Queen’s veil over the surface gently.
  6. Stipple gently by vertical brush movement ensuring thorough wet out.

Note:

  1. Strictly ensure that there is no horizontal movement of the brush as the fibre wash will displace the design on queen’s veil.
  2. Also use fine bristled white haired brushes, not coarse bristled brushes as they may also tend to displace the fibres and hence the Design Texture.
  3. Wet out thoroughly any dry patches by further application of Roof light OR Clear GP Resin (about 90-110 gms. Per sq. mtr. )
  4. Allow to cure to touch tackiness.
  5. Apply a coat of Pigmented Resin.
  6. Lay CSM of the required density as per requirements.
  7. Wet out the CSM thoroughly with Pigmented Resin.
  8. Additional layers of CSM/Woven Rovings may be laid as per design requirements with Pigmented Resin.
  9. Allow to cure.
  10. Extract from the mould.
  11. Polish or buff only if required.

For Making Rooflite Sheets/Wrinkle Glass/Translucent FRP/GRP Mouldings and Corrugated Sheets using QUEEN'S VEIL :

The procedure is same as the normal method.

PLYWOOD LAMINATION USING QUEEN'S VEIL :

  • Clean the plywood thoroughly.
  • Prepare a polyester putty which is to be applied over the plywood.
  • Spread the prepared putty evenly over the plywood with a squeeze or a spatula and allow curing until tackiness.
  • Gently apply the " QUEEN’S VEIL " by hand and press it down into the putty uniformly making sure that there are no air pockets.
  • Using a spray up grade of polyester resin suitable for lamination, Spray a thinner grade of polyester resin uniformly over the " QUEEN’S VEIL " liberally so as to ensure that complete wetting takes place allow to CURE.
  • Sand it as recommended by the resin supplier.
  • Additional layers as per design requirements maybe laid, sanding each layer as required . Allow to cure thoroughly.
  • Polish or buff as required.

Note:

  • Polyester putty may be prepared by using polyester resin + filler (eg calcium carbonate).
  • Such putty must be pigmented for receiving the “QUEEN’S VEIL".
  • Pigment it by adding white pigment to milky colour and then add the required colour pigment depending on the shade of the "QUEEN’S VEIL" being used.

For Logos & Labels using Queen's veil:

Logos & Labels are increasingly applied to finished mouldings for Brand - Imaging or for Identification. When applying these, proceed as follow:

  • Clean the surface of the finished moulding thoroughly.
  • Apply a coat of Pigmented Resin.
  • Allow to cure to touch tackiness.
  • Apply a coat of Roof light OR Clear GP Resin OR Gelcoat.
  • Lay the Label/Logo gently and ensure there are no wrinkles.
  • Apply a further coat of Roof light OR Clear GP Resin & allow to cure.

SPECIFICATIONS FOR PIGMENTING BACKUP LAYER

Correct pigmenting of the CSM layer Resin is necessary to bring about proper quality of the colour and the texture of the finished product.

Please Note:

  • Only Ultra -Violet light stable pigments should be used in the back-up CSM layers for out door applications.
  • This is a crucial precaution as normal unstable pigments may fade on prolonged exposure to sunlight and damage the colour effect of both the "QUEEN’S VEIL" and also the finished laminate over a period of time.
  • Hence for high levels of light exposure, please use Polyester Resins with UV barriers.
