Acrylic polyurethane topcoat

描述

Product introduction:

A two-component room-temperature curing topcoat based on special hydroxyl acrylic resin, aliphatic curing agent, pigments, fillers, solvents, additives, etc.

Physical parameters :

Performance characteristics:
1. High weather resistance: Acrylic polyurethane topcoat has high weather resistance. It can withstand long-term UV irradiation outdoors without powdering the paint film. It has outstanding weather resistance and is resistant to artificial aging for 100 Ohm. This paint can be used with other products for 8-10 years and is also a commonly used product for outdoor anti-corrosion coating.
2. Chemical resistance: The paint has excellent chemical resistance, acid and alkali resistance, acid rain resistance, salt spray resistance, salt water resistance, etc. It has excellent water resistance, oil resistance, and three-proof properties. The paint film can resist atmospheric corrosion. Effectively protect the substrate.
3. Strong mechanical properties: The acrylic polyurethane topcoat has strong mechanical properties, and its impact resistance, flexibility, and wear resistance have reached industry standards. It has excellent adhesion, the paint film does not fall off, has long-lasting protection, and has good mechanical and physical properties; 4
. Beautiful and decorative: The paint has various colors, adjustable tonal gloss, tough paint film, good fullness, high gloss, full paint film, and beautiful coating. It has good decorative protection and long-term use in outdoor environments. The paint film retains color and gloss, and does not fade.
Application fields:
Steel structures for large bridges, port machinery, engineering machinery, containers, ships, gas refining tanks, storage tanks, high-pressure spherical tanks, hydropower stations, substations, transmission towers, chimneys, aviation signs, etc. requiring long-term protection and decorative topcoats.
2. Surface treatment requirements: When painting metal surfaces, sand blasting and shot blasting are required to remove rust to the national standard Sa2.5, keep the surface dry and free of oil, dust and other foreign matter, and paint within 4 hours. 3. Mixing
ratio : Weight ratio 4 (base material): 1 (curing agent).
Construction process:
Open the barrel and stir: Open the barrel and add the matching curing agent for stirring, and use special diluent to adjust the viscosity.
4. Painting method: airless spraying, air spraying, or brushing.
5. Theoretical coating rate: 0.20~0.25 kg/square meter under the condition of dry film thickness of 60~80 microns.
6. Thinner dosage: Special diluent can be added appropriately according to the construction conditions, and the dosage is 5~15%.
7. After the last topcoat is applied, it must be naturally cured for 7 days before it can be put into use. If the ambient temperature is lower than 10℃,
it should be extended appropriately.
Supporting system:
Acrylic polyurethane topcoat can be matched with a variety of coatings and used in various industrial environments:
Front primer: epoxy zinc-rich primer, epoxy primer, epoxy cloud iron intermediate paint, acrylic polyurethane primer Paint etc.
1. Steel structure anti-corrosion: epoxy zinc-rich primer + epoxy mica iron intermediate paint + acrylic polyurethane topcoat; epoxy primer + acrylic polyurethane topcoat
2. Bridge anti-corrosion: epoxy zinc-rich primer + epoxy mica iron Intermediate paint + acrylic polyurethane topcoat; inorganic zinc-rich primer + epoxy sealer + epoxy mica iron intermediate paint + acrylic polyurethane topcoat 3.
Engineering machinery coating: epoxy primer + acrylic polyurethane topcoat
4. Building exterior Wall decoration: epoxy sealing primer + epoxy mid-coat + acrylic polyurethane topcoat
Packaging specifications:
21: 4KG/set
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.
Note:
The curing agent and diluent of acrylic polyurethane topcoat are specially used for special paints and cannot be mixed with other varieties. 2. The
mixed paint must be used up within 4-6 hours to avoid solidification, gelation and unusability of the paint. Open the bucket If the bucket cannot be used completely after being covered, the lid should be sealed in time to prevent solvent evaporation from affecting use.
3. It is not suitable for construction in windy, rainy and snowy weather to avoid paint diseases.
4. Construction workers must take safety precautions, such as wearing masks, gloves, etc.
5. The paint should be stored in a cool and ventilated place. The storage period is 12 months.
Health and safety
please Pay attention to warning labels on packaging containers. 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.
