Request Information
Chemglaze® M331/M201 elastomeric coating is a two-component polyurethane coating designed to produce a tough, flexible film for use in protecting the leading edges of fixed and rotary wing aircraft. This coating accommodates thermal expansion and contraction, and functions exceptionally well to protect the underlying substrates from abrasion, erosion and minor impact damage. Chemglaze® M331/M201 coating can also be used as an effective protective coating in the highly abrasive environments of the railroad and mining industries.

Features

Features and Benefits

 N/A
  • Durable: Provides outstanding resistance to abrasion, erosion and impact; conforms to ASTM D-16 Type IV classification.
  • Easy to apply: Can be applied by pressure pot or HVLP spray equipment; builds thick films easily with one application of multiple coats.
  • Versatile: Can be used to coat a wide variety of substrates such as metals, concrete, plastics and foams.
  • Primer and topcoat compatible: Provides excellent adhesive properties when used in conjunction with Aeroglaze® epoxy or wash primers, and Aeroglaze and Chemglaze® aliphatic moisture-cure or two-component polyurethane coatings.

Uses

Uses

Directions for Use

Surface Preparation

 N/A Thoroughly clean surfaces to remove all dust, oil and grease. For most substrates, apply primer to ensure proper adhesion and performance of the coating.

Mixing

 N/A Mix ratio of coating is 3 parts Chemglaze® M331 (Part A) component to 1 part Chemglaze® M201 (Part B) component by volume. Thoroughly stir Chemglaze® M331 component, making certain to incorporate any material that may have settled at bottom of container. Once Chemglaze® M331 component is well mixed, continue stirring while adding Chemglaze® M201 component. Thoroughly mix the two components until uniform in consistency. Note: Both Chemglaze® M331 and M201 components are sensitive to atmospheric moisture, especially M201 component. Only open Chemglaze® M201 component when ready to use.

Applications

 N/A Apply coating at ambient substrate and surface temperature of at least 10 ºC (50 ºF), with substrate temperatures at 3 ºC (5 ºF) above the dew point.
Chemglaze® M331/M201 coating is best applied by airless spray equipment with no thinning required. Thinning is not recommended for high build applications.
For application with HVLP spray equipment, dilute coating with Chemglaze® 9951 thinner. Depending on application, the mixed coating can be diluted up to 30% by volume with Chemglaze® 9951 thinner.
Chemglaze® M331/M201 coating is recommended for medium to high build applications, ranging from a minimum of 356 micron (14 mil) to 762 micron (30 mil) applied in multiple coats.
A second coat of Chemglaze® M331/M201 coating or a topcoat of another Chemglaze® coating may be applied after the first application has cured a minimum of 4 hours at 15.6 ºC (60 ºF). Chemglaze® M331/M201 coating can be coated after one day if parts are kept clean. For maximum intercoat adhesion, recoat within 24 hours. Chemglaze® M331/M201 coating cannot be applied directly to metals. Metals require the use of a wash primer and/or an epoxy primer to promote adhesion of Chemglaze® M331/M201 coating to the substrate. In many cases, Chemglaze® M331/M201 coating will adhere directly to properly prepared composites, plastics, foams and other non-metallic substrates. However, a test patch may be required to determine if a primer is required.

Curing

 N/A Cure begins immediately once Chemglaze® M331 and M201 components are mixed. Chemglaze® M331/M201 coating cures by reacting with moisture in the air. Cure rate is dependent on the temperature, relative humidity and amount of air circulation needed to remove the solvent.
The applied coating must be cured above 10 ºC (50 ºF) and 60% relative humidity. If the percent relative humidity drops between 30-40%, moisture should be supplied by steam or water to the curing environment. Under the acceptable curing conditions, the coating will set to touch in 15-30 minutes, surface dry in 1-2 hours, and dry hard in 4-6 hours. Lower temperatures and humidities will retard cure.

Cleanup

 N/A Use Chemglaze® 9951 thinner to clean equipment. Clean spray equipment immediately after use since the coating will cure inside guns, filter screens and hoses. Once Chemglaze® M331/M201 coating cures, it will be more difficult to remove. Circulate solvent through the hoses for at least 15 minutes to help flush and clean the hoses.

Precautions for Use and Storage

Precautions for Use and Storage

 N/A Shelf life of each component is six months from date of shipment when stored in a dry environment at 16-24 ºC (60-70 ºF) in original, unopened containers. If the storage temperature drops below 10 ºC (50 ºF), Chemglaze® M201 component may crystallize.

Allow material to return to recommended storage temperature for two days to remove crystallization before using. Do not mix or use material until crystallization is removed.

Before using this or any Socomore product, refer to the Material Safety Data Sheet (MSDS) and label for safe use and handling instructions.
