EXTERIOR POLYCARBONATE WATER BASED
URETHANE TOP COAT

MPI Listing Numbers:
Exterior: MPI-193, MPI-194
Interior: MPI-128, MPI-181

The FIRST waterborne exterior grade clear coat to be approved by Master Painters Institute (MPI), Target EmTech 9300 is a non-yellowing water based polycarbonate urethane coating engineered to provide exceptional adhesion to wood and engineered wood-type substrates.  Formulated as a final topcoat for high-end applications such as exterior architectural woodwork, structural fixtures and applications that requires a flexible coating in high UV exposure environments.  Formulated with state-of-the-art biocides, UV control agents and polycarbonate resins, EmTech 9300 offers excellent chemical resistance, weather-ability and UV stability when exposed to direct sunlight.  When used in conjunction with Target EmTech 8800 Universal Sealer a polyester-type fill and build can be achieved.

The clarity and depth-of-image of the EmTech 9300 is exceptional.  When reduced with distilled water EM9300 can be used as a penetrating sealer. EM9300 can also be tinted with water based universal oxide colorants for use as a exterior grade stain system.

EmTech 9300 Polycarbonate Urethane is available in Gloss (90°), Semi-Gloss (65°), Satin (35°) and Flat (10°) sheens.

Target Coatings EM9330 Satin Polycarbonate Urethane Exterior Wood Finish
500-Hour QUV Test Results

The following information represents QUV Machine UV/Water Condensation Testing of the Target EM9300 Polycarbonate Urethane Wood Finish in a satin format over a 500-hour machine exposure period. 

Panel Preparation

Three coats of the EM9330 under test were applied using a 6 –mil gap application bar on 3" ´ 6" pine wood panels.  The side of the panels to be varnished was sanded using a 180–grit sand paper.  Panels were then placed in oven at slightly above 100° C for 30 – 45 minutes to remove any water present.  Each coat was allowed to dry for 24 hours before the application of the next coat.  A 320–grit sand paper was used to sand between coats.  After the application of the third coat, panels were allowed to dry for 7 days.  At the conclusion of the drying period, panels were placed in the accelerated weathering QUV machine for 500 hours.

Results

Gloss reading comparison was used to evaluate the performance of the satin sample.

The satin varnish showed acceptable sheen adjustment after 500 hours of UV/condensation exposure.
