Product Info for UNITHANE HS-18
UNITHANE HS-18 is a newly developed, high solids (45%), pure waterbased aliphatic polyurethane resin designed as a basecoat to give excellent fill and coverage. UNITHANE HS-18 forms a very soft, flexible polymer film with low surface tack and excellent print retention and cut-thru resistance. This resin is unique in the fact that it has 100% recovery after 1000% elongation, which provides excellent elasticity and “finish memory”, when used as a basecoat on split and grain leathers.
UNITHANE HS-18 is designed as a high solids, filling basecoat. This may reduce the number of total coats needed for finishing and lead to reduced cycle times and more efficient manufacturing. UNITHANE HS-18 has excellent flexing properties to include dry, wet and cold flex (-20°C) as well as cold impact testing at -30°C.
Suggested application method is to roll coat. For starting point formula, contact your Union Specialties Inc. representative.
