GWR Nano Insulation

GWR Nano Insulation

Work process


For the application of the GWR Nano Insulation thermal insulation

The GWR Nano Insulation liquid insulating coat contains microscopic (0.03 - 0.008 mm) hollow ceramic balls uniformly distributed in a liquid mixture, which is the mixture of synthetic rubber, acrylic polymers and inorganic pigments. The material retains its unique properties both under hot and cold conditions of use.

The thermal insulation of the surfaces should be performed between + 5 ° C and + 250 ° C surface temperature limits.
The transport and storage of the material is not permitted at temperatures lower than +5 ° C.

1. Preparation of the insulating coat

No special preparations are required for the use of the GWR Nano Insulation thermal insulating substance; mix it thoroughly prior to use, and dilute it with distilled water, if necessary.

1.1         Remove the lid of the bucket.
1.2         Break the film, and push the thickened film into the fluid gently in the middle and on the sides using a flat wooden blade until the liquid covers thefilm.

1.3         Moving the mixing blade vertically, submerse the thickened portions of the material into the liquid, then mix the contents of the bucket with a stirring rod slowly to stir the thickened portions with the liquid.

1.4         Continue stirring it until the thickened film fully dissolves and a smooth "cream-like" substance is obtained which contains no lumps.
1.5         The mixed material is poured into a clean bucket through a sieve. The sieve’s mesh size should be between 0.5 and 1.0 mm. The remaining lumps should be removed to avoid that they block the disperser.
1.6         The layer thickness of the GWR Nano Insulation thermal insulating material applied in a single cycle can be 0.6 mm (five tool cycles), the application of next coat is allowed after at least 8 hours at 20 ° C. The layers should be applied one after the other squarely.

The GWR Nano Insulation insulating material is no paint, but an insulating coat. Do not use high speed for mixing the fluid, because you may destroy the ceramic and the silicon balls.

The revolution of the drill used for the mixing must not exceed the 300 rev / min value.


2. Surface preparation

The material spreads on any kind of surfaces well: metals, wood, plastic, glass, concrete, brick, etc.
It is important that the surface to be insulated should be dry and free from grease.
2.1         The surface to be insulated should be cleaned from dirt, dust, remains of old paint, rust, etc. (using a metal brush, broom) and degreased (any degreaser can be used).
2.2         First the metal surfaces should be cleaned with a metal brush to remove any rust and loose material and dust, then it is degreased, then one should wait until the degreased surface dries.
2.3         In advance, any concrete or brick surface should be brushed to dedust it. Then wet the surface with water, and apply theGWR Nano Insulation thermal insulating layer.
2.4         When the water has dried, apply another layer of GWR Nano Insulation primer over the surface, let it dry for one hour, and after priming, apply the material as described in Section 1.6. After each primer or insulating layer, apply the insulating layer one after the other squarely.
2.5         From the wood surfaces, first the dust and then – if possible - the resin should be removed.
2.6         The plastic surface should be rubbed with a piece of leather (to remove the finish), then it should be dedusted and degreased.

3. Tools, equipment

3.1         The GWR Nano Insulation thermal insulating material should be applied over the surfaces to be insulated using an airless atomizer or a long-haired, soft, natural brush.
3.2         For large surfaces (50 sqm or larger surfaces, 300 mm or bigger tube diameter) Ultra Max Graco695, Graco795, Graco 1015 or analogous model airless atomizer should be used. Maximum pressure: 230 bar (23 MPa), working pressure: 80 to 140 bar.

4. Preparation of the atomizer for work

4.1      Before you start applying the material, perform the preparatory tasks detailed in the factory specifications.

5. The preparation of the material for use

5.1 Before you start applying the material on any surface, apply a primer layer with a brush (go through the surface twice with the brush) and allow it to dry (for at least one hour at room temperature).
5.2       Making the primer:
1)  As a first step, mix a test amount of primer (500-700 ml) in a one-litre bottle from the GWR Nano Insulation thermal insulating material prepared as described in section 1.3. Add distilled water. The amount of the added water depends on the preparation of the surface for insulation and of the ambient temperature. The lower the temperature, the less water is needed. The starting amount of water is 20 ml and not more. The surface should be even without cracks (loss of water at high temperature) or leakage (excess water at a low temperature; the boiling point of the GWR Nano Insulation thermal insulating material is +67 - +70 °C, polymerization at +95 °C)
2)  Measure the amount of water required for the given volume, and mix it thoroughly.
Please note: determine the amount of water for each primer in a bucket or container individually.
5.3         During priming, stir the mixture continuously to prevent the light material components from rising to the top of the liquid. The thickness of the layer applied with a brush in one cycle is 0.08 to 0.1 mm.
With the Graco 695 equipment: 0.006 – 0.008 mm.
5.4         Preparation of the insulating material
Mix 1 litre of material with about 0.2 to 0.3 decilitre of distilled water thoroughly.
5.5         The thickness of the GWR Nano Insulation thermal insulating material’s layer applied in a single tool cycle is 0.15 – 0.2 mm. One technology layer is 0.45 – 0.5 mm. (2 primer layers + 2 layers of material, Annex №1 to TUU)

The thickness of the applied material – with all the layers - can be up to 0.6 mm. Before applying the next layer, wait until the previous layer has dried. (See Section 1.6)


6. Hot surfaces

6.1         If the surface temperature is between 70 ° C and +95 ° C, use thinner primer (section 5.2).
6.2         If the surface temperature is between 80 oCand +120 oC, use even thinner primer (section 5.2).
6.3         On hot surfaces, the number of the primer layers is 3x - 5x using more thin primer. At high temperatures, the primer aims to reduce the surface temperature to the boiling point of the GWR Nano Insulation . The drying time of a layer on hot surfaces is significantly shorter (duration: 30 minutes to one hour).

 Do not dilute the material with water for priming of cold surfaces!


7. Checking the thickness of the applied coat

7.1         The thickness of the coat should be checked after the complete drying of the surface, using:
  • a Caliper SC 125-0,1
  • a Micrometer 0-25 GOSZT 650788 (for inspection during technological production)
  • a TP – 34 thickness gauge
7.2         The amount of the used material depends on several factors; a separate document contains the specification:
 (Annex №1/2 to TUU 26.2-31797789-001-2002 23rd November, 2005)

8. Work safety regulations

8.1         While working with the material, the regulations of SZNiP 111-4-80, SzanPii 6027A-91, GOSZT 20010, GOSZT 1    2,04,013, GOSZT27575, and GOSZT27574 must be observed.
