NextStone™ Product Test Data

NextStone™ has conducted extensive testing on its products and proprietary non-flammable

in–mold coating system. The details and results of some testing are as follows:

NextStone™ Hardness / Adhesion Test

Test Purpose: The hardness / adhesion of the coating to the substrate depends on the

process used to finish the substrate, the coating thickness and the drying of the coating.

Test Results: Minimum hardness requirements based on anticipated use were met.

Required class for adhesion was also met.

NextStone™ Xenon Test

Test Purpose: In the natural environment, rupture may occur due to the factors of

temperature, humidity, sunlight and oxidation resulting in the color, gloss, hardness,

adhesion and flexibility of the coating being changed. We use the ARC Artificially

Accelerated aging test to measure the weathering resistance of the coating.

Test Results: No evidence of surface deterioration, surface shrinkage, objectionable

color or gloss change, delimitation, lifting, cracking, pitting, blistering or other

degradation.

NextStone™ Salt Spray Test

Test Purpose: Rusting, bubbling and fading can occur due to salt spray on all

materials. This is especially true when the product is used around the seaside, at the

beach and in industrial

districts which have high strength salt spray (fog).

Test Results: No rusting, bubbling or fading occurred.

NextStone™ Hot / Cold Cycle Test

Test Purpose: The process for the hot / cold cycle test is as follows: The total cycle

time is 5-10 cycles. The sample is put at a constant temperature of –20 degrees C for

two hours and then at 50 degrees C constant temperature for 2 hours. The sample is

then visually inspected for cracks,

blistering or other visible damage.

Test Results: No cracking, blistering, etc. was observed.
