Acrylic powder, also known as acrylic resin in the printed circuit board production process, in order to monitor the PTH hole plating thickness, line etching undercut rate, metallographic sectioning microscopy. Metallographic section acrylic powder and hardener, is a U.S. imports of acrylic resin as main raw material the metallographic slice molding of special chemical products, with a steady and rapid cure at room temperature, the bubble is small, long-term storage does not change color, hardness high acid and alkali, excellent performance. 

 Unique advantages: * Curing is rapid, stable, good transparency * low viscosity, excellent flow properties and excellent permeability * slice curing * holes and depression after the slice has a good supporting role * sliced ??cured stiff enough sufficient brightness * and toughness * slice polished slices before and after curing shrinkage is very low * can be used for all known soft or hard plastic mold 
 Physical and chemical properties Appearance: acrylic powder: white powder, its particle size below 100 microns, the molecular weight of 150,000 Mw to 160,000 Mw, Hardener: Colorless to light yellow transparent liquid. Flammability: acrylic powder, when the temperature or open flame burning, hardening agent is a volatile flammable 

 Injected into the mold, wait until the full curing can use: the hardening agent and acrylic powder ratio of 1:1 (weight ratio) mixed, slowly stir (avoid the generation of artificial bubble), curing time is about 7 to 8 minutes, this product contains defoamer, when used appropriately generally will not be sparkling produce, For a more perfect slice, the choice of the Division I Technomat vacuum pressure cooker, suitable temperature (° C): 10 ° C - -45 ℃; component ratio (weight ratio) acrylic powder: curing agent = 1:1 

 The use of safety. Not excessive inhalation of vapors, must be well-ventilated indoor operation; 2, the operation is not encountered in flame and temperature; 3, at low temperature, dry place, and not touch the fire and organic solvents
