8710 drinking water interior paint
IPN8710 interpenetrating network anti-corrosion coating
描述
Product introduction:
IPN8710 interpenetrating network heavy-duty anti-corrosion coating is a two-component coating. Group A base material: resin, initiator; Group B base material: active monomer, catalyst. When Group A and Group B are mixed in equal amounts, the three networks interpenetrate at the molecular level to form an interpenetrating polymer network (IPN) structure, producing a synergistic effect. The network formed by this coating has: strong adhesion, good flexibility, Resistant to acid, alkali, salt and other corrosive media. It further improves the toughness, strength, adhesion, anti-permeability and chemical inertness of the coating, giving the coating film better performance. It improves the performance of the polymer by forming IPN. It is a new type of polymer blend. technology.

Product features:
good anti-corrosion performance and strong adhesion.
The network interpenetrates at the molecular level to form an interpenetrating polymer network (IPN) structure.
It is a graft-type interpenetrating network polymer that initiates polymerization at room temperature. The two networks can learn from each other’s strengths and weaknesses, creating a synergistic effect.
A new anti-corrosion coating with high strength, high toughness, abrasion resistance, hydrolysis resistance and excellent insulation properties.
Resistant to acid, alkali, salt, sea water, boiling water corrosion and chemical atmospheric corrosion.
vApplication
fields:
Mainly used for the inner walls of drinking water pipelines, reservoirs, and safety oil tanks (non-toxic and harmless and some edible fields).
Construction process:
Construction conditions
: The substrate temperature should not be lower than 5°C, and at least 3°C higher than the air dew point temperature (temperature and relative humidity should be measured near the substrate), and the relative humidity should not be greater than 65%. Good ventilation is usually required to ensure the paint dries properly.
Construction method
: Spraying: airless spraying or air spraying. High pressure airless spraying is recommended. When using air spraying, attention should be paid to adjusting the paint viscosity and air pressure. The diluent should not exceed 10%, otherwise it will affect the coating performance.
Brush coating: It is recommended for pre-coating and small area painting, but the specified dry film thickness must be achieved.
Packaging and Storage
The storage environment should be dry, cool, well ventilated, avoid high temperatures, and keep away from fire sources. Packaging containers must be kept tightly closed. The effective storage period is 12 months.
Precautions:
If the bucket cannot be used completely after opening the lid, the bucket lid should be sealed in time to prevent solvent evaporation from affecting use.
Health and Safety
Please pay attention to the warning labels on the packaging container. Use in a well-ventilated environment. Do not inhale paint mist and avoid skin contact. If paint is spilled on skin, wash away immediately with suitable detergent, soap and water. If it splashes into your eyes, rinse them thoroughly with water and seek medical treatment immediately.
