ThreeBond Ultra Glass Coating

Three Bond is a Japanese brand since 1955. A major manufacturer of Industrial adhesives, sealants and auto-after products. Three Bond supply products to Automotive, Electronics manufacturers, Computer parts maker and Industrial companies. It has always been innovative market leader in creating durable & quality products. And with the growing industry, we aim to continuously create more products that would always satisfy our customers ever increasing demands and expectations to be more advance with the new technology.

“Ultra Glass Coating Classic” is the next-generation coating system for automobile body which delivery long-term protection of automobile paint surface by giving a glass-based hard coating. “Ultra Glass Coating Classic” is formulated with a new generation material called ‘Silane”, which reacts with moisture in the air and transforms to a glass-based coating. The glass-based hard coating that prevent deterioration of the paint surface and provide excellent weathering resistance thus protect the glossiness of the painted surface. “Ultra Glass Coating Classis resists deterioration caused by oxidation and reject the damaging effects of UV ravs, therebv protecting the paint color fading and uneven discoloration. With the smooth and slippery laver make the dirt will be washed off with rain and provides excellent antifouling effect. The hard and heat-resistant coating of the “Ultra Glass Coating Classic” effectively protects the body from high temperatures, dust, minor scratches, etc.

*With “Ultra Glass Coating Classic”, there is no need to use conventional waxes as the vehicle will stay beautiful with the superior and easy maintenance characteristics of the body coating system.

Product Features


Effectiveness of antifouling with smooth surface

Smooth Surface

  • Lubricating roll down the water droplets.
  • Effectiveness Antifouling (Acid rain, water drops & dust.)
  • Easier Maintenance (Water Wash)


Sliding water test results with automotive painted plate

Plate A 2 sec 28 sec
Plate B 2 sec 26 sec
Plate C 2 sec 27 sec
Average 2 sec 27 sec

Test Method: Keep the painted board which applied classic 30 degrees. Drip of 0.05ml water at 150mm from the bottom of the plate. Measure the time reached the bottom of the plate.
As evidenced in the test results below, when it rains, a drop of water flows quickly to the body surface.
So, you can reduce dust and dirt away with a raindrop.


Effectiveness of antifouling with smooth surface

Test Method: Check the degree of adherence of dirt with use a piece of white bumper as a test piece, dip and raise repeatedly with the water containing the dirty substance.



Effective protection of iron dust with glass-based coating

Test results of iron dust adhesion
Test Method: Spray iron dust to test piece that painted with white paint. With use of “Iron Dust Remover”, the adhesion degree was observed with determining the coloring. Iron dust reacts with “iron Dust Remover”, and empurpled.

Protection from UV rays with glass-based hard coating

Silane witch reacts with moisture in the air and transforms to a glass-based hard coating. This glass-based coating protects the painted surface from ultraviolet rays.
(Cutting rate W-k10-25% UV-B:25-75%)


This glass-based coating protects the painted surface from ultraviolet rays.

Types of UV Wavelength (nm) Characteristic
UV-A, Long wave 320~400 It reaches the surface of the earth
UV-B, Medium wave 280~320 Be absorbed by the ozone layer, some reaching Earth
UV-C, Short wave Below 280 Be absorbed by the ozone layer
