Properties

Great savings on Time and Labour

Qunly BW9300 series coatings offer high adhesion to all sorts of surfaces,can be applied directly onto to even the rusty or chalking coating surfaces.There is no need of sand blasting and may be applied onto wet surfaces.The coatings are primer and top coat all in one products,dry quickly in room temperature and firm a sufficient thick coating.Hence,the products offer great advantage of labour and time savings,also offer extra convenience to all sorts of fieldworks.The products can be used in atemperature range of 5℃ to 50℃.

Superb protections

Qunly BW9300 series coating give superb long lasting protections to the working surfaces in even very hash conditions.Such as strong direct sunlight and other hash weather condidtions.The products are also highly resistant to chemicals,impact and wears.The products can with stand of 5000 hours of wet and high temperature test and 10000 hours of salty watervapour test.The standard type of the products offer more than 10 years of working life and the heavy duty tyes give at least 20 years of superb protections.

Environment friendly

All Qunly BW9300 series coatings contain no acieds,lead ,chromium and other harmful heavy menials.There are very little industrial wastes during the production,hence,favorable to the envireonment.The products are also no-toxic,can be used on running drinking water equipment.

Approval for ins plus.effective protective alility

Tested by various State Authorities,BW9300 series coatings passed rigorous tests by the Statde Coating Qality Monitoring and Testing Centre.The Ministry or Industrial Machinery,the Wuhan Material Protection Reserach Institute,The Coating Testingn Centre for Navy Equipment and the Navy Vessel Material Test Centre and numerous other professional bodies.The tests were based on the following standard The working surface preparation:St2.0.The natural salt vapour test:10000 hours.The wet and heated test:5000 hours.Ther weigh loss by wear:0.01g/1000r.1000g.The BW9300coating test results with lower requirement on surface preparation (St2.0)proved even better than those achieved by the other competitors both domestic,joint venture or foreign when tested on a surface prepared to sand blast on Sa2.5 standard.The guide commonly used in the trade for convert the rate in the laboratory against natural vapor test is equivalent to a steel structure been left one year in the nature ocean weather environment.Based on this rate the 10,000 hours of exposure to a bal neutral salt vapour test is equivalent to 50 years of anti-corrosion protection life.
