Surface Treatment
2007/8/29
| 1. | Treating metal works with different shapes with special technology and equipment for satisfying customers' requirements. |
| 2. | We are provided with a sour rain tester (ERICH SEN) imported from Germany and a saline water-fumigating tester, for making complete test to each butch of finished products. |
| 3. | Continuing research for better material for reducing its cost and upgrading products with its anti-corrosion effect possible to last long so that your products may have stronger competitive force. |
Film category (King Tec)
| 1. | The product is at first electrically or mechanically plated, and then its outer surface is treated with special resin material, forming a colored coated layer possible to resist dense saline mist and sour rain. |
| 2. | Products have smooth surfaces, and coatings have no scars, choosing colors according to customer's request. |
| 3. | Carrying out perfect plating even to needle holes in the bolt head of any shape, with less than 1% hole block percentage. |
| 4. | Possible to carry out saline-water fumigating test 500H-2000H {according to ASTMB-117 (test standard.)} |
| 5. | Sour-rain resistant test being more than 15 cycles {according to DIN50018.20 (test standard.)} |
| 6. | High abrasion, using an electric drill with 1300 RPM for drilling a screw in an ACQ wood and then |
| pulling out to get a result that the outer coated film does not peel off, with the bottom layer | |
| protected sufficiently , upgrading protective effect of the products after used. |
Anti-abrasion test
Insert an electric drill with RPM 1300 in an ACQ plate, and then pull out, getting the result that
the surface is complete, without any damage.
Other companies use the method as the same as above, and get the result that the plated
surface is exposed.

KING TEC treatment does not produce public hazards.
| 1. | Having no problem of pollution by wastewater. |
| The KING TEC treatment is a kind of coating, having no washing process to exhaust harmful substance and endanger the environment. | |
| 2. | Having no problem of pollution by waste gas. |
| The KING TEC heating treatment for hardening produces volatile substance, which has been tested and proved to be not harmful with any bad odor gas by the Environment Protecting Bureau. | |
| 3. | Having no problem of bad working environment. |
| The working environment of our factory has been inspected by the testing department of the Environment Protecting Bureau, proved to have no harmful substance, with body health or workers sufficiently protected. | |
| 4. | Having no problem of waste chemical liquid. |
| In our working process, the material liquid is all circulated, producing no waste liquid, and a little material for washing is to be treated by a recycling system for reuse. |
ASTM B-117/CNS 4158 Salt Spray Test
| Item | Dissolving | Testing |
| Salt concentration(W/W%) | 5% | 5% |
| PH value | 6.5 | 6.5~7.2 |
| Pressure of compressed air(kgf/mm2 ) | 1.0±0.01 | |
| Amount of sampled atomized solution(ml / 80cm2 /hr) | 1.0~2.0 | |
| Temperature of compressed room(oC) | 47±1.0 | |

Kesternich Test
| Symbol | Duration of cycle | Duration of individual actions(hrs.) | Temperature in testing room | Relative humidity% | Addition of SO2aper cycle(Liters) |
| SFW0.2S | 24hrs | 8 including heating16 including cooling (apparatus opened) | 40±3 oC Room temperature | below 75 | 0.2 |
| SFW0.2S | 24hrs | 8 including heating16 including cooling (apparatus opened) | 40±3 oC Room temperature | below 75 | 0.2 |
According to AS-3566, failure is considered to have occurred when corrosion of steel substrate is well established as witnessed by the presence of red rust over 15 percent of the significant area of any individual sample.
