Testing

Nema has been tested at the Azuma Design testing facilities for its reactions to and the absorption of petroleum, hydrochloric acid, turpentine, water, thinners and methylated spirits. The results showed no or very marginal effects and no moisture absorption for all substances except thinners. 

Substance Test Number Test Duration Result
Water AZT0191.08 96 hours No substantial effects or changes
Petrol AZT0188.08 96 hours No substantial effects or changes
Hydrochloric acid AZT0192.08 96 hours No substantial effects or changes
Turpentine AZT0190.08 96 hours No substantial effects or changes
Methylated Spirits AZT0189.08 96 hours No substantial effects or changes
Thinners AZT0193.08 96 hours Sample split and lost rigidity

For further information on these test results or product samples please consult a NEMA representative.

Nema has also been tested by Wattyl for paint adhesion, an extract of the report indicates the strong performance of Nema to painting.

"We have evaluated the adhesion of various waterbased and alkyd enamel based products over the samples of Nema board. The coatings evaluated covered the following ranges:

• Solagard applied directly to Nema board
• Solagard over i.d Primer Sealer Undercoat
• BriteGlo waterbased acrylic applied directly to Nema board
• BriteGlo over i.d Primer Sealer Undercoat
• i.d Gloss Enamel directly to Nema board
• i.d Gloss Enamel over i.d Multi Purpose Undercoat (oil based)

All systems had good adhesion to the board, although the use of i.d Primer Sealer Undercoat did improve the adhesion of the Solagard and BriteGlo waterbased acrylics.

The board also showed good resistance to a wide range of organic solvents".
