Pattern Resin LS is a self-curing, general purpose acrylic resin used for making patterns for fabricating copings, post and core build-ups, lingual and palatal bars, implant attachments, adhesion bridges, clasps, telescoping crowns and certain pre-soldering techniques. This product is formulated to provide a perfect fit. It is ideal for dentists and laboratories who perform difficult restorations due to the fact that it sets quickly with minimal shrinkage, allows both direct and indirect pattern making, and leaves no residue after burnout. 100g powder.
