IPN8710-2B special equipment for drinking water equipment

Overview: The special coating for drinking water equipment is based on IPN8710 Polyurethane Polyethylene Coatings and a new generation of non-toxic paint developed with epoxy water tank coating. It is modified by epoxy resin and polyurethane resin, and is added with no toxic fillers and additives. Such as composition, with good corrosion resistance, rust resistance, strong adhesion, fast drying, non-toxic, non-irritating properties after curing. The hygienic safety of the coating complies with the hygiene requirements for the soaking water of protective materials in the “Regulations for the Safety Evaluation of Drinking Water Distribution Equipment and Protective Materials for Drinking Water” of the Ministry of Health.

Scope of application: The IPN8710-2B special equipment for drinking water equipment is suitable for the equipments contacted by drinking water, the surface anticorrosion and the anticorrosion and coating of concrete surfaces such as water tanks, water tanks and other surfaces.

Precautions:

1: The material must be planned during construction. The paint is mixed according to the proportion, fully stirred and allowed to stand for 5-10 minutes before being applied, and the rest of the materials cannot be poured back to the original barrel; the paint must be applied before the paint is dry on the front surface;

2: The pipeline interface should pay attention to the removal of dirt, water traces, pay attention to avoid damage to the anti-corrosion coating backfill;

3: The winding glass fiber cloth must be flattened and the mesh is filled with paint;

4: The painted object should avoid damage during transportation and hoisting;

5: The construction site should pay attention to ventilation, rain, snow, fog days should not be outdoor construction, paint should be placed in a cool, ventilated, dry place, and isolated fire.

Technical parameters: refer to the comprehensive parameters in the IPN8710 polyurethane polyethylene interpenetrating network coating profile
