lomitwrench LO/MIT Technical Specifications

The LO/MIT products are silver-colored, non thickness dependent, low emissivity radiant barrier paints. They may be used in almost any application where infrared (heat) reflectivity or diffuse light reflectivity is required, ranging from attic heat barriers (Interior Radiation Control Coating Systems-IRCCS) to heat shields in automotive applications, lighting fixture reflectors, reflective radiant barrier roof coatings, aeronautics, appliances, process piping, power generation and many other applications. Their high temperature tolerance, low emissivity, excellent adhesion, UV resistance, flexibility and weather-durability make them unique in the field of high technology industrial coatings. They are the ONLY 1 part, premixed heat reflecting coatings in the market.

OPTICAL CHARACTERISTICS

Laboratory application of LO/MIT-I on glass substrates have lowered emissivities from 0.860 to 0.210 and increased diffuse reflectivities from 7.3% to 85%.

Laboratory application of LO/MIT-II on glass substrates has lowered emissivity from 0.860 to 0.170 and increased diffuse reflectivity from 7.3% to 86%.

Laboratory application of LO/MIT-II MAX on glass substrates has lowered emissivity from 0.860 to 0.145 and increased diffuse reflectivity from 7.3% to 87%.

SURFACE PREPARATION

Normally, adhesion is the only factor that will be affected by surface preparation. Optical properties will remain constant except on surfaces that are very porous such as brick and cement. To improve optical properties and extend coverage on porous surfaces, appropriate primers may be used to increase surface smoothness. On metallic substrates such as cold rolled or galvanized steel that may be subject to possible corrosion or oxidation, appropriate primers should be used. In all cases, the surface should be dry and free of oil and surface dust.

Surfaces that are already painted or primed should be tested for compatibility with LO/MIT-I by applying a small test patch for possible reaction to the solvents used. LO/MIT-II & LO/MIT-II MAX will normally not react since they are water borne systems.

Plastics may require surface treatment to increase adhesion and should be tested for compatibility with LO/MIT-I. LO/MIT-II & LO/MIT-II MAX have not been found to react adversely with most plastic substrates.

Most building materials such as wood, plasterboard, paper faced insulation batts, fibrous ceiling tiles and painted metal roof decking require no surface preparation except that they be clean and dust free. Masonry surfaces should be allowed to cure for a minimum of one month prior to the application of LO/MIT-I, II or II MAX.


INSTALLATION

lomitLO/MIT radiant heat barrier paints are low viscosity coatings and may be installed using standard air or airless spray equipment. Spray nozzles should be appropriate for coatings that approximate the viscosity of water. Spray pressures should be kept as low as possible to lessen over-spray but also yield a uniform surface coat. Remote pressure pots should be equipped with air driven agitators. In all cases, the coating should be mixed during application to keep the pigments in suspension. Electrostatic application requires that the coatings be tested for the equipment being used. Additional solvents may be required for good electrostatic application.

LO/MIT may also be applied using low nap rollers or fine bristle brushes. Coverage rates will drop approximately 25% when applied in this manner. Brushes and rollers should be solvent resistant when using LO/MIT-I. Rollers are preferred since brushes will generally leave streak marks in the surface.


CURING

LO/MIT-I will skin dry within one minute after application. Full cure will generally occur within 15 minutes to 1 hour depending on ambient temperature and humidity.

LO/MIT-II will skin dry within 5 minutes after application. Full cure may take from several hours to several weeks, depending on ambient temperature and humidity conditions present, so avoid contact and abrasion during this time.

LO/MIT-II MAX will skin dry within 10 to 15 minutes after application. Full cure may take from several weeks to six months or more depending on ambient temperature and humidity conditions present, so avoid contact and abrasion during this time.

Curing can be accelerated by application of heat up to 400°F (204°C) for 15 minutes. Do not exceed temperatures of 400°F with LO/MIT-II. Do not exceed temperatures of 1000°F with LO/MIT-I or LO/MIT-II MAX. Experimentation will determine the best curing procedures for your particular environment.
