NAME:
Envirothane 170 White Primer High Solids
PRODUCT CODE:
ELPR170
DESCRIPTION:
ELPR170 is a universal urethane primer that provides an excellent foundation for any solid colour systems on MDF as either a 1K or 2K product. When using PR170 on veneer, solid wood or in a refinish situation it is necessary to use the product as a 2K system by adding CAT100-LV Hardener to improve adhesion and prevent cracking or checking of veneers and soft woods. This 70% solids high-hide primer lays down very flat and provides unsurpassed filling properties especially for MDF, where it does not swell the fibers like other water based products in the market. It offers fast dry times and is easy to sand without being easy to sand through.
USES:
This product is designed for interior wood finishing applications such as cabinetry, tables, furniture and millwork.
PRODUCT PREPARATION:
Reduction is not required when spraying with Air Assisted Airless or Airless, however, adding 3% RX010 reducer will help the product to lay down extremely flat reducing the amount of sanding required to level sand prior to top coating. Reduction is reccomended for pressure pots, HVLP turbine, conventional cup guns or brush and roll. Product should be at room temperature and mixed thoroughly prior to application. Drill mix any soft settling off the bottom of a can is reccomended.

SANDING:
Sand raw wood or veneer with 150 or 180 grit to remove any mill glaze or oxidation. Sand MDF with 240 – 320 grit sandpaper especially any machined (saw marks, edges & routed-out areas) prior to applying primer. Sand primer with 320/400 grit sandpaper or fine/super fine sponges. Two coats can be applied same day back-to-back without sanding between and still acheive good adhesion, a quick scuff is required if more than 8 hours elapsed between coats. All of our primers must be sanded same day as topcoat application as they cure quickly, if the primer is sanded and left overnight it will require a quick scuff with maroon scotchbrite or a super fine sponge for adhesion before applying topcoat.
DRYING TIMES:
