Shellac Finishes

SKU: SF-Royal-Lac Post Catalyzed & Catalyst

Royal-Lac Post Catalyzed wood finish is a shellac based finish formulated with a blend of synthetic resins. Post catalysis helps in creating a cross-linked polymer that is far superior in terms of fast curing, chemical resistance, and hardness.  Royal-Lac Post Catalyzed is specially designed for spray equipment suitable for small to large scale finishing operations. It can also be brushed and padded/wiped on. French Polishing is not recommended. Some of the benefits that it offers are:

  • Fast cure - curing is complete in 5-7 days after last application
  • Quick drying - coats are dry in about 30 minutes; re-coat is recommended every 1 hour
  • 4-5 coats can be sprayed within a span of 8 hours
  • High solids content of 40% by weight
  • Low VOC - less than 275 grams/liter
  • Ready for sanding and buffing after cure
  • Looks and feels just like shellac but with exceptional durability
  • Can withstand more than 150 MEK double rubs
  • Hardens to greater than 6H Pencil Hardness
  • Great adhesion due to shellac being a major component in the formulation

Mixing procedure:
Mix Royal-Lac Post Catalyzed finish with the supplied catalyst in a 7:1 ratio, i.e. mix 7 parts of Royal-Lac Post Catalyzed with 1 part of RL-Cure catalyst. Use metal or glass containers for mixing. Plastic containers are not recommended. Only mix as much product as you will use. The pot-life of this product is 8-10 hours.
