MIROBILD AC 3770 Pigmented Topcoat

Code: 3770

A high solids, fast drying, pigmented, two-pack acid catalysed coating. Aromatic free and low formaldehyde. It provides superior physical properties and chemical resistance when compared to single pack lacquer coatings.

Features

Features

  • Fast drying rate and long pot life make it ideal for automatic line operations
  • Results in a tough resilient film that protects quality furniture and fittings.
  • High build, provides maximum build with the minimum number of coats applied
  • Low yellowing, ideally suited for application over blond timbers and liming stains
  • Low formaldehyde, provides a safer working environment for persons applying the coatings, and compared to conventional acid catalysed coatings, superior in-service air quality around the coated article.

Application

Application

Mixing Ratio (by volume) : 10 Parts MIROBILD AC 3606 Part A + 1 Part MIROBILD AC 3800 Universal Catalyst or MIROBILD AC 3810 Quick Dry Catalyst by volume. Mix A & B and then add thinner. Allow mixed product to stand for 15 minutes prior to thinning, this will ensure that maximum film hardness and clarity is obtained. Failure to allow time for reaction to take place may result in a hazy film.
Pot Life : 1-2 days at 25°C Pot life varies significantly with ambient temperature, humdity and the quantity mixed. Pot life is longer at lower temperatures and shorter at higher temperatures.
Thinning : Thin up to 30% with MIROSOL 1220, 1222 (Fast), 1294 (Medium), 1242 (Slow). In hot or draughty conditions up to 10% MIROSOL 1218 Ultra Slow Thinner may be added. Do not exceed 10% addition as it will retard the drying and could lead to problems with sanding, printing and blocking. Use faster thinners to achieve the required viscosity and then use (only if required) a small amount of MIROSOL 1218 to improve flow and levelling. In damp, cool or high humidity conditions, up to 10% MIROSOL 1297 Retarder may be added to help prevent blushing (a milkiness or haze in the film). Heating the application environment e.g. warming with infra-red lamps and avoid spraying early in the morning and late evening when temperatures are at their coldest, will also help to reduce the risk.

Suction Gun - Use 1.5 to 2mm (59-79 thou) orifice with 350-400kpa (50-55 psi)
Pressure Pot - Use 1.5 to 2mm (59-79 thou) orifice with pressure pot air-cap. Gun pressure 350-400kpa (50-55 psi) and a pot pressure of 45kpa (6 psi) max.
Airless Spray - Use 0.23 to 0.33mm (9-13 thou) orifice, 15cm fan (dependent on job) with regulated pump pressure of 350-400kpa (50-55 psi).
Air Mix Guns - Settings similar to airless spray with the air-assisted regulator pressure at 70-90kpa (10-15psi).
Curtain Coating - Viscosity 40-50 seconds.
