The invention relates to a high-rigidity reinforcement-bulging-resistant PU (Poly Urethane) 
crystal transparent primer 
coating. The PU 
crystal transparent primer 
coating is prepared from the components in percentage by weight: 25-30 percent of acid-
alcohol resin, 40-50 percent of modified 
acrylic resin, 3-5 percent of 
zinc stearate, 10-15 percent of glass 
powder, 0.2-0.4 percent of additive and 7-10 percent of 
solvent. Due to adoption of the special modified 
acrylic resin, the high-rigidity reinforcement-bulging-resistant PU 
crystal transparent primer 
coating has the advantages of small molecular weight, strong rigidity, rapidness in 
drying and 
solvent dilution and the like; and as the glass 
powder with strong rigidity, good transparency and good fallibility, as well as a curing agent and a 
diluent with a proper proportion are used, and thus the PU crystal transparent primer with strong rigidity, rapidness in 
drying, good fillibility and high transparency is prepared, so that furniture products made of deep wooden eye wood such as 
meander belts, ebonies and the like, which have the problems of reinforcement bulging, collapse, poor transparency and the like, can be solved, the quality and the market value of the deep wooden eye furniture products are greatly improved, and the requirements of consumers and the market are satisfied.
