W305 ENVIRONMENTAL PROTECTION AND EFFICIENT PRIMARY TREATMENT COATING

W305 ENVIRONMENTAL PROTECTION AND EFFICIENT PRIMARY TREATMENT COATING
W305 ENVIRONMENTAL PROTECTION AND EFFICIENT PRIMARY TREATMENT COATING
Product Code : 04
Product Description
W305 environmentally efficient primary treatment coating is the introduction of foreign advanced technology,Using synthetic resin as basic material,water as the dispersion medium,choice imported raw materials,maked environmentally friendly and efficient automatic descaling,anticorrosive primary treatment coating.For severe corrosion of steel structures,can eliminate the traditional sand blasting, shot blasting, grinding rust and other tedious process,sprayed directly on the rust or rust-free steel appearance,to achieve the automatic rust, rust excellent protection performance.

Where to use
It can be widely used color steel roof, steel structures, bridges, ships, containers, machinery and equipment, storage tanks, petrochemical pipelines, construction of buried pipelines and other steel components grassroots rust, rust and corrosion protection.

Product features
  • Water-based environmentally friendly products, no solvent pollution, non-toxic, non-flammable non-explosive.
  • Without the traditional sandblasting, grinding rust and other tedious process, directly rusted construction.
  • Can be used with any water-based and oil-based middle, supporting the use of surface coating.
  • High permeability, rapidly penetrate the steel corrosion oxide layer, and forming a dense blue-black protective film.
  • Improve coating adhesion and overall protection performance.
  • Construction is simple and convenient, tolerance and strong.

Construction Conditions
Construction should choose sunny, ambient temperature should be in the range of 5-40 ℃, relative humidity below 85% preferably,not be below 5 ℃ construction.

Primary treatment
Before coating, using blades, steel brush to clean the metal substrate surface water, sand lime, welding slag, oil, loose thick rust.

Construction guide

  • The construction method: spraying, brushing, roller coating, dip coating
  • spraying air pressure is set to 0.4 ~ 0.6Mpa, gun caliber of 2.0 ~ 2.5mm, must use spray gun or brush that not been construction by oily coating.
  • W305 single-layer coating amount of 20 square meters / KG, and can be adjusted according to the corrosion status single-layer coating weight or adding coating construction after surface dry.
  •  After W305 coating hardening6 to 12 hours, steel surface rust oxide has gradually been converted into a dense layer of epidural blue-black protection, Then you can use our W301 or W302 products to rust, corrosion primer construction.

Precautions:
When using direct use of concentrate (special case clean water dilution ratio up to not more than 3%)

Before using, coating with a wooden stick must be fully stir well, don't stir with iron, it is prohibited to use rosin water, petrol, xylene, day take water for dilution solvent.

Work is completed or coffee breaks,need to clean up gun or brush with water, can also be thrown them into a plastic bucket fulled with water,Can avoid coating solidified block the spray gun or make brush dry and hard. 4.W305 belongs reactive coatings,If cannot run out onceshould pour out suitable amount of coating in other containers for spraying or brush to use,avoid to fall back coating that has not used up in the construction into the bucket,the construction process should avoid rust metal objects fall off the bucket,lead to product reaction and failure.

Storage and quality assurance
Store in a cool ventilated place, tightly sealed, shelf life of one year

Specifications: 20KG / bucket

Handling and transportation
Careful handling. In transit can not be reversed, damage, collision, avoid sunlight, rain and ice. The product is water-based, non-toxic, odorless, non-flammable, non-explosive belong to the "non-dangerous goods rules.
